Tranny Temp.

[ThrottleJunkie]

Does anyone know what the average automatic tranny temp should run?
I asked 4xyota and he said he had seen 240-250.
My C-4 is running at 200-205
my Duramax is 195, unless towing enclosed to Winnamucca gets to 205
When is to hot?
What damage can be caused from to much heat in tranny?
:dunno:

[MR.ROCKAPE]

I ALWAYS THOUGHT IT WAS SUPPOSED TO BE CLOSE TO ENGINE TEMP....AND THAT IT GOT DANGEROUS FOR THE TRANS IN THE 230+ DEGREES(JUST LIKE AN ENGINE....)

I WOULD LIKE TO KNOW AS WELL AS MY NEW BUGGY IS GETTING A TRANS TEMP GAUGE.....AS WELL AS A BIG COOLER WITH ITS OWN FAN.

[T_MADD]

I also wonder about this. My dodge ctd runs 170-190 empty. I start to watch the gauge closely when it gets over 200 while pulling a good load. I'm sure 200ish isn't hot but I don't know how much past that before it is.

x2 my 04 has seen 220 when i was pulling my tractor to reno in august and trupster called someone he knew about trannys and said thats not that bad. mine usually never gets above 200 though

[BryanD]

i've always went with and heard it should run similar to the engine, so 180-210. with a grill mounted cooler and a chassis mounted cooler with its own fan i can keep my F350 & 30' Class C motorhome under 220 even when pulling/towing up big hills like the Bishop & Mono Lake grades.

my F350 around town is often 120-140 without even turning the fan on. on a hot summer day in stop/go traffic it will go up to 180-190.

my buggy crawling is cool also, 150-180. but at sand mountain it will often be over 200, and have seen it hit 250 once running it hard, but let it cool quickly.

here is an interesting chart that gives some "guestimates" of tranny longevity VS temperature. keep in mind, the longevity would be running the trans consistantly at those temeratures.

i think the cooler you can run them the better.

[T_MADD]

That chart makes me feel better.

:dunno:

get on thedieselplace.com and look for MikeL tranny cooler. He makes some kits for the Dmax's that really drop the temps.


also as far as engine oil goes I dunno if its different for trannys or not, but our newer ISX cummins powered trucks run constantly at 250 degrees or more for the engine oil temp and cummins has a thermostat in them for the oil cooler.

[DSI]

200 degree's in a NON Lockup trans wheeling is not bad. 220 is the worry point really. And placement of the temp sender is also important to those readings.

my TH350 temp sensor is right at the outlet from the converter, to the cooler. the hottest place in the trans.

if you run 200-220 and change the fluid a time or two a season it's not as big of a deal.

how much converter are you running?



And tow rig temps are a little different as they have a lockup converter, and even certain tran's have thermostat's to the cooler so they stay in an operating range.

[1SAWB]

A QUICK SEARCH AND I FOUND THIS :Big Grin: ALSO FOUND OUT THAT THE FLASH POINT OF NON SYNTHETIC FLUID IS 428*F

How does heat affect transmission life?

TRANSMISSION FAILURE/TEMPERATURE CHART

Most automatic transmissions fail due to a breakdown of the transmission fluid (oil) caused by overheating. This chart provides a graphic display of heat's contribution to transmission failure.



The effect is also cumulative. Short term exposure to high heat levels (or even prolonged exposure to moderate heat) can break down the oil to the point where even very short episodes of overheating will lead to failure.

We recommend a TRANSMISSION PROTECTION KIT as the most important deterrent to transmission failure. A PROTECTION KIT with cooler should be installed once, and then a PROTECTION KIT with flusher used every time the transmission is serviced.

The PROTECTION KIT with cooler includes a high capacity inner fin transmission cooler, an inline filter, and LUBEGARD supplement. The PROTECTION KIT with flusher includes a transmission cooler flusher, an inline filter, and LUBEGARD supplement.

[B2Krawler]

my old c4 ran above 250 for years, (c4s are very hardy), sometimes hit 270ish on hot days. even when i took it apart and rebuilt it still looked good inside

that tci tranny fluid at summit, keeps my new tranny so cool, it takes a hot day just to budge the gauge



your not even close to the danger zone IMO

[ThrottleJunkie]

Tranny pegged 250 gague this weekend and started to piss fluid 2 hours off trailer:Crying:
still drove but needed to rev motor to engage:eek:

[RADDONKEY]

:dunno: What happened??

[ThrottleJunkie]

:dunno: What happened??

Just started to have fun , did little wall at lower PH, death bowl, and a couple other obsticals, then went to other side of PH and when I got there 250. stayed and let it cool down then drove back to trailer and it got hot again and started leaking pretty good.:Crying:
Tranny builder says it probably the pump, so will try and get tranny back out ASAP

[RADDONKEY]

DANG IT !!

[jeeper89]

that sucks.. i was wondering why you were not behind me anymore when we went to find everyone else

[ThrottleJunkie]

Gonna pull tranny this weekend and install new pump:Crying:

[ThrottleJunkie]

So still havn't pulled tranny but put gague on tranny and gague has presure in every gear and idle. But tranny lines stay cool to cooler even when tranny is 250. Why is tranny pumping and appling clutches but zero flow through cooler?:dunno:
Any input would be apreciated.

[85runner]

Lines and cooler free from clogs?

[BryanD]

i know the engine goes on one end, and the transfercase on the other. did you check that?

[Double-a]

Last week I had my Allison up to 290 :Crying:
Everything still works fine but I am doing a tranny flush just to make sure I dont blow my tranny (when it happened I had 16k behind me while I was headed up the Sierras and my tranny did go into safe mode, after a quick reset with an OBDII reader, everything was good to go).
My brothers Ford on the other hand.
We got his tranny up to 260, it popped a line, wipped out the torque converter and stripped out every gear but first/reverse.

I would reccomend you try to find the op temp for your trans and stick with that. They all seem to be a little different.

I have a T-400 in my trail rig and the damn thing is bullet proof, I have had it past 300 and it never missed a shift (I did change the fluid in it the nest day, just to be safe).

Just like everything, there are good ones and bad ones!

i love giving people shit!:Big Grin:

[RADDONKEY]

That sucks, but at least you know why its getting hot. Unfortunaly is going to need to come apart to find the reason there is no flow to the cooler. Is you trans guy going to make it right for you?? If not I know several. :dunno:

[ThrottleJunkie]

He is, Paul jr. seems to be a really good guy :Big Grin:hopfuly he helps me pull it though, so my wife won't have to help again:eek:

I'll help you pull it, just a phone call away! :Big Grin:

[Double-a]

I am pretty handy with a set of tools and when I got out of the military I worked in a tranny shop for a while.

All I did was pull and install tranny's but if you need a hand and I have the time to be there, I can help out

[ThrottleJunkie]

Right on! thanx guys:Big Grin:

any chance you can get it fixed by sunday:gapteeth: im free to help out saturday nights:Big Grin:

Better plan on puttin clutches in that thing, once they limp they do it a lot easier the next time. Also look into that cooler for it, they really did help drop the temps in mine towing.

Funny you menton that, did it again yesterday on my way out of Fernly towards Silver Springs. Forgot to take it out of OD and it went back into safe mode.

Only does it with 10K+ behind me and only when I forget and leave it in OD.
Now that my Banks is currently working, the code was easy enough to reset, but it was quite annoying.
So you think the clutches need replaced ehh.
Fuck, thought that tranny was the one thing on the truck I would never have to screw with. The allison was the reason I bought that truck.
Owell.
Guess that is what happens when you use these rigs for their intented purposes?

The allison will live forever with stock power, but once you add any kinda chip to it and it slips it will just start getting worse. Thats why I was recomending my buddy if you wanted a built trans that will handle whatever you wanna throw at it for cheap causes he's done a crap ton of them in town for people. I think he's still a dealer for suncoast parts too. Even though banks claims to be safe on the trans you gota figure by the time it detects trans slipage and backs the power off, its basically to late and the bitch is already slipping.

Basically with stock power the Allison probably wouldn't see those temps. I don't know about the LBZ and LMM trucks and newer, but the LB7 and LLY trucks can upgrade the stock cooler for dirt cheap and drop at least 50 degrees on the Allison temp

The 1st time it happened I was caught complety off gaurd. Not sure what happened. Guess it was just like you were explaining, the trans slipt and then went into safe.
The second time it happened, it was my fault. I dont know what I was thinking, I just forgot to take it out of OD. It hasnt happened since. I pretty regularly tow loads like that so I am pretty sure the second time was my fault.
You have given me some food for thought though. I am going to start putting some money asside to get my trans gone through.

Regarding the T-350. I think the best place is to put them right in the pan. With a steel pan it is the easiest. Pull the pan, drill a hole, and weld in a bung. Of course there is the cheating way, just add some 3/8th's ID line (or larger) and plug the sensor into that.

Regarding the over sized trans cooler for my Dmax, I was just planning on getting an alluminium AC condenser from a car, having it cleaned and adapting that as my new trans cooler.
I cant think of any reason why it wouldnt work, my only concern is that it might impead the air flow to my rad and intercooler. Any thoughts?
I also have a small 2 core alluminium rad from 4 cylinder Honda. It has plastic resiovors and that is a bit of a concern but it dosent have a rad cap, not sure how it was filled? must have been through a resivor. I was thinking of maybe going that route. It will be a bit more complicated to install but I think it will offer a lot better cooling as it will increase my trans fluid capacity substancially

[ThrottleJunkie]

So I had my tranny rebuilt at a shop in carson about a month ago. The first time I went out the tranny was 220 or so. This was on no rocks just dirt roads. The first time I went wheeling was at prison hill when the tranny spiked at 250 after a few obsticals. I have a custom pick up in a deep pan so it will pick up at steep angels. He had told me that the pick up may be to close to the pan working the pump to hard and making it run to hot. I dumped all the burnt fluid and shortened the pick up. The next time I went out was at hacket a couple of weeks ago. The tranny ran at about 215-220 until the first obstical when it spiked to 250. After letting it cool I could only run it about 20 minutes at a time befor having to stop and let it cool. when the tranny was at 250 I could touch the cooler and lines and they were cold but touch the pan and you would loose your finger prints. I pulled the tranny again and he said he took some check valve balls and springs out to make it run through the cooler at all time full flow. Went out this weekend to run wakitt and the tranny was 215-220 all the way to the first obstical where it then hit 250 again. I checked the cooler lines and they were hot this time. I let the tranny cool and proceeded on. The tranny stayed right at 245 for the rest of the day without puking any fluid until the ride home. When we got out of the canyon and I put it in 2 high and was driving on dirt roads the tranny hit 250 and began to puke fluid right as I got to the trailer. I left it on the trailer all night and most of today. Whe I went to unload it I pulled it off the trailer and drove it into my garage. I pulled in a little to far and when I went to put it in reverse nothing happened. I started to smell fluid hitting the exhaust and when I looked under my jeep it was puking fluid at a alarming rate. WHAT THE FAWK DO I DO NOW!!!!! If I pull it again and give it back ,I run the risk of just putting it back in with more problems again. I'm really getting sick and tired of wasting my weekends taking this damn thing in and out, not to mention all the money in fluids. Plus missing out on good wheeling. Right now I am at risk of loosing my wheeling time for Memorial weeknd!! This same tranny has been in this jeep for ten years without issues, never once evere getting over 210 on the hottest and roughest of wheeling days. I NEED ADVICE SOMETHING FEIRCE!!!!!!!!!6640

[EastCoast44]

So it ran cool in the past with the coolers you have now? Then it started running hot after a rebuild? I would definitely get a second opinion from another trans shop. Try calling Levrett in Reno and see what they say. More than likely if you talk to some other shops about it they might be familiar with the problem you're having.

[BryanD]

levi,
i dont know much about trannies but something is obviously wrong. beyond the pickup and cooler size i would guess. i dont think my tranny hit 180 all day doing Wackitt. its close to ten years old, been behind my old V6, and now my 5.3 AND bought it used to begin with (knockin' on some wood here).

i think Pep Boys sells remans for $599!:rolleyes:

maybe you need a new tranny guy. the only guy i trust is Mark Levrett, and he isnt even official in the business anymore.

[MR.ROCKAPE]

damn, tranny problems bring the suck...especially since its been out twice!!! I would send you to the guy I know from Sheldon but he only does GM trannys.......:dunno:

Though I have never used Mark Levrett I have heard he knows his stuff!!!

[EastCoast44]

I actually work with Mark, but his dad owns Levrett on 4th st. I can see what Mark says, but he dad seems to know more that Mark does. Kind of inevitable since he's older!

[BryanD]

Levi,
are you using your old converter? i know the converter builds a lot of heat in a trans. maybe something is wrong with it.

[ThrottleJunkie]

No, new converter from hughes. Its a 1800 rpm stall. I still have my old stocker. Going to try to figure out where all the fluid came from last night, and may start to pull tranny again today. I would like to put old converter in, just don't know for sure that will help? My tranny guy said he has seen converters bad straight out of the box. At this point I'm starting to look like a nascar pit crew getting the thing in and out!

[RADDONKEY]

Levi that really sucks, What does your trans guy sugest?? Seems to me that he should take some resposibilty and make it right. :dunno: Since it worked fine before he rebuilt it. Not trying to throw him under the bus, but I'm just saying!! Somethings not right. :rolleyes:

[ThrottleJunkie]

he says he is sorry and I need to pull it again and bring it back to him. I am sort of stuck in a rut, so to speak. Not real sure how to handle the situation.Can't really afford to have it rebuilt somewhere else. That was a $275 rebuild kit plu $325 for him to rebuild it. I talked to him this morning and he said he is not going to give up, but there was no mention of fault or reimbersment. That tranny worked fine befor but I just don't know what to do. Maybe drink hard liqure and reflect on my situation:beer::bored::bringit:

ERIK HAS DONE QUIT A FEW C4'S JUST DOENT LIKE TO. I COULD CHAT WITH HIM :dunno:

[Double-a]

can you tell exactly where the leak is coming from.
If you look at the bell housing there is a weep hole, if the fluid is pouring out of there (it is located directly under the torque converter) then the trans is more than likely toast. I could be something as (simple) as a cracked torque converter or the pump may have been damaged. This is assuming the leak is from the weep hole. Hard to tell without seeing it, regardless, as your aware, there is a significant problem there.
Everyones suggestions about getting a different mechanic are sound. Sounds like this guy is a bit shaddy. However you probably have the problem that if you went to a different guy you would have to pay him, and this guy I assume is fixing (or trying to fix) his mistakes on his dime.

I would suggest taking the whole rig to your guy and having him pull the trans, fix it, and re-instal it.
I dont think it is a good idea to pull the trans, put in the old t-converter and re-instal it, I do not think this is going to fix your problem and all it will end up doing is pissing you off when you have the same problem after having done all that work...again.

[ThrottleJunkie]

It looks like the fluid blew past the cover on the driver side. Not sure what that is but has four bolts with a round shape in it.:dunno:

it's a simple gasket swap. but it still doesn't solve the heating issue. I have a few idea's that might help ya out. If you have solved the no fluid flowing to the cooler issue, then I think there's an easy step to the next issue.

[ThrottleJunkie]

I do have fluid flowing through the cooler now. :Big Grin:I found this on a search that says 250 during normal operation and 300 for towing and racing applications is normal for a C4.:dunno:

But please, all info is appreciated. Bestow your vast knowledge upon me squiral master. :bowdown: (that was not my sarcastic voice, I really need some help with this issue.)
As far as fluid blowing out the side cover, it may have had a little to much in it under closer investigation. Not sure that would make it do that?

COOLER! a BIG COOLER! my trans would hit 245 just doing a couple quick runs up horsepower with my B&M plate cooler, now, with my 5qt PWR i can run an entire 300 mile race and not break 180. that plate cooler would have had me at 500 degree's in 50 miles.


you need more cooler!

[ThrottleJunkie]

:Big Grin:

[EastCoast44]

you need more cooler!

For some reason I thought it ran cool before the rebuild? :dunno: If not then yeah, a bigger cooler would be a good idea.

[ThrottleJunkie]

Yes the gauge never got over 215 on the hottest and roughest of wheeling days before the rebuild, however I have moved the sender from the line going to the cooler to the pan now. I must say the first time when the cooler wasn't getting any flow the fluid was burnt and a brownish color, now since he has corrected that problem the fluid is not stinking and has the same red color it should. My cooler is a six pass 10 1/2" by 21" cooler with a fan mounted to it. It is mounted in the back where as not to get preheated from the radiator. I may resael that side cover and try to push it this weekend at prison hill just to see what happens before pulling it a third time.

[Double-a]

COOLER! a BIG COOLER! you need more cooler!

You can never have to much cooler IMO

[DSI]

Stock trans with stock converter vs higher stall (heat) converter, and all new tighter (friction = heat) internals.

after my rebuild mine runs cooler. I took the time to measure all my frictions and steel's, and to make sure all my tollerances were perfect this time. dropped about 15 degree's operating temp. nothing else changed.

[ThrottleJunkie]

Just got done putting new O-ring in side cover. Now it doesn't leak but there is no damn reverse:complain:
So just to recap here. pull tranny first time to have it rebuilt because fluid was a little dark and tranny had been in crawler for ten years.
Put $2000 into new lower first, second gear servo, 1800rpm torque converter, 4130 input shaft, deep aluminum pan, and rebuild kit with kevlar bands and all new steels. Already had Art Carr manual valvue body with compresion braking.
Tranny burns all fluid first time out. Notice no fluid going through cooler. Pull tranny again and now fluid is going through cooler and fluid is not burnt but still runs 250 degrees.
next time after wheeling pull into garage and go to back up and tranny spews fluid everywhere with no reveres. change O-rings and add fluid still no revers. Going to pull tranny a third time now and even my dumb hard headed ass has had enough of this shit.:eek:
LEVRETT HERE I COME!!!!:clap:
The only C-4 known to man that is going to have $1,000,000,000.00(sure hope it backs up!)

god damn dude... if i were you, i'd probably go have a nice chat with the guy who built it the first 2 times about some sort of restitution. Have someone else who probably has a better chance of getting it right build it, and when you re-install it..... BUY A BIGGER COOLER!

Well no moonrocks for me on Memorial. My $475 lower than stock first gear poped a c clip and was coocking itself. Took 3 weeks to get that one and who knows how long to send that one back and be replaced:Crying: Was thinking of replacing that whole C-4 for some hampsters in a wheel!:complain:

[85runner]

Not good news man. I hope for a quick replacment gear for ya.:cool:

[ThrottleJunkie]

TCI says they are going to honor their warranty and should have another one in a week:Big Grin:(they say:dunno:)

[ThrottleJunkie]

Not good news man. I hope for a quick replacment gear for ya.:cool:

[BryanD]

[boxmuncher]

are we thinking of finishing WACKET!!!!!!!!!!

[ThrottleJunkie]

Well if your gonna Wacket, you might as well finish it:gapteeth:

the c4 is like the easiest tranny to rebuild, you should just do it yourself if they dont warrenty it. I have the C4 rebuild manual if you need it, also just rebuilt a spare one for my rig. sounds like the plates are too tight if its getting that hot, also i would recommend the TCI ATF fluid at summit, it keeps the tranny real cool.

you have a lot of bling parts in yours, so maybe there is some sort of interference. i know its kinda late now, but not sure if would have got the lower 1st gear, mine never even sees 1st gear because its too low, and mine is stock.

i went with a TCI streetfighter TQ, which is only 2-300 rpm over stock, next time i will go with stock

just more to think about

[ThrottleJunkie]

I was really impressed with the lower first gear. Between the stall (1800 RPM) and the lower first it has a lot more get up and go in high range. When in low range with a 4.3 transfer case I am still in first on every obstical. I only have 5:13 in the axles with 40" tires. The stall on the obsticals took a little getting used to. But even with a stock 1500RPM stall when I'm on an obstical I am rearly at or above 1500RPM, so I'm slipping the tranny most of the time no matter what. I will definatly go to the TCI tranny fluid and it looks like the heat was coming from the first gear being sloppy and rubbing the inside of the bell. It wore a pretty good groove in the bell and had signs of bluing. I told them when they send it back to over night it no matter what the cost because I am ready to wheel!!! At this point if shit doesn't start to look up I will go yank one out of pick n pull and run anything.

You know if you go to the junk yard and get some shitty looking trans thats covered in dirt and oil it will probably last forever.

[boxmuncher]

Well if your gonna :wackit:, you might as well finish it:gapteeth:


GOOD POINT
