Title: 2006 duramax tranny getting hot???
Post by: trophyhunt on July 05, 2022, 02:18:10 PM
Iíve never had a problem towing my 29í trailer before, this weekend going up chinnok pass I had to pull over and let my tranny cool down  :bash:.  Changed the fluid and filter about 40,000 ago, fluid looks and smells fine.  Looking at some YouTube videos it might be debri in my cooler.  Anyone have any ideas??  Thinking of just replacing the cooler and bottom cooler line, is that easy???  Or am I missing something ?

How hot, Jerry?  Do you have a digital readout gauge?

Title: Re: 2006 duramax tranny getting hot???
Post by: trophyhunt on July 05, 2022, 02:32:28 PM
Not digital, just the gauge on the dash, said 275-280 ish

That's hot.  I would guess a blockage, but other's will know more.
Good luck!

A blockage makes sense to me, and new stock GM coolers are only 154.00 on rockauto. Itís an easy thing to check off the list anyway, not sure how tough the job is.

If you really hit 275-280 odds are that you are going to lose a seal or two at some point. At those kinda of temps auto trans tend to not last very much longer at all. Definitely sounds like a blockage or trans was not locked up! Not sure how the fluid smelled ok at those temps. The fluid is cooked for sure.

flush, blow out cooler.  I would put big cooler on but would think duramax has it ???  TruCool Max 40,000lb units are best I've found.

It's an Allison should have a big cooler on it...mine did anyway.

And ya...fluid is cooked. If your gauge is accurate... normally she'll start slipping at those temps...

Flush, fluid, filter and cross your fingers

It should be a stock cooler, which I would think is a good one. but I've heard flushing is a joke??  I bet it would cost more to flush than just replace, IF i can replace it myself??  I'm going to replace the fluid and filter this weekend, then when it's empty try to pull the bottom line off and see if I can look for debris.  I sure hope it's not ruined, allison is the best is all I've heard, I hope it's tough enough to handle a little heat.  I guess if I start seeing fluid on the ground I'm screwed, maybe I can sell it to Mags or another liberal, that way I can sleep at night.   :chuckle:

It won't all ever drain...lines are full. Torque conv is full...flush is the only way to expell all the old fluid....

If you mess it up I'll buy it from ya...since it's got an LBZ in it... :chuckle:

Just curious how many miles on yours.

I also have a 2006 Duramax /Allison. 
Just got back from Colorado yesterday.
About 88K miles on it now.

17.3 MPG to Colorado and back, cruise set at like 72. 
I was disappointed in that.

Sorry for the thread jack. 
I will be following

Replace that fluid asap, itís trashed
Buy a larger pan to hold another gallon of fluid and donít worry about trying to upgrade a cooler right now.  Unless you canít unplug it, if it really is plugged. 
I got a larger pan on my Cummins last year and rarely exceed 175 while towing 8k up cabbage hill in the summer.

Post by: trophyhunt on July 05, 2022, 06:14:21 PM
162,000 on the truck, coach was saying the cooler is prob fine, he recommends changing inside and outside filters, as well as fluid.  Also check lines to make sure they arenít kinked and pull return line and start engine, fluid should pump out pretty good.  I like the idea of a bigger pan! I was going slow up chinook, coach was saying that hill is a bad one, steep and low speeds can heat up tranny.
Title: Re: 2006 duramax tranny getting hot???
Post by: Mudman on July 05, 2022, 06:21:57 PM
First of all if it was at 280 degrees it is likely toasted.  Fluid is junk for sure.  Second idiot light gauges arent that accurite.  Third you SHOULD smell it if its burnt.  Smell it, does it stink or normal odors?   Your clutch linings will literally be falling apart if ya bake em at 280 so I was told by expierenced tran tech years ago.   I would look at cooler plug from dirt bugs etc.  Also is fan working properly at temp?  Example my Ram never exceeds 170.  I just did Blewitt with toy hauler loaded at speed in heat as well.  With price of fluids and such I would spend my $ at GOOD tran shop for diagnoses if needed. :twocents:

Post by: trophyhunt on July 05, 2022, 06:53:58 PM
Fluid doesnít smell bad, had another guy smell it as well, he thought it smelled normal. Iím hoping my gauges are off. My fan kicks on and cools the water temp very well.
Title: Re: 2006 duramax tranny getting hot???
Post by: HntnFsh on July 05, 2022, 08:30:55 PM
Those temps dont sound right. 100 over ambient is normal temp for an Allison. If the fluid doesnt smell burnt it probably isnt. You have to drop the pan on those. No drain plug. The internal filter is considered a lifetime filter. Saying that I dropped my pan and and changed the filter on my LBZ last year. When you change the spin on, only run Allison filter and make sure the magnet is in place. You can do a double dump on the tranny fluid if your concerned. Dump, fill, run a bit, dump, and fill again. Considered to be as close to 100% new fluid as you can get. Ive heard good and bad about bigger pans. Dont really think they are the cats meow myself, but thats just me. You get that extra gallon of fluid hot its going to take longer to get it cool.

Go over to the Duramax forum and ask questions or do a search. Lot of very knowledgeable people over there to help you out.

I would call the folks at Puyallup Transmission.  I'm on my second Duramax and tug alot.  They have ALWAYS  been good with my Transmission problems no matter which vechile I own and never have oversold me.  AT A minimum flush and have them pull the pan.  Chinook Pass is not that bad of a tug so get it checked out.  Happy Trails.

Post by: trophyhunt on July 11, 2022, 06:38:27 AM
Yes, well, actually no I guess. lol.  So this weekend I changed the inside and outside filters and changed the fluid.  I was gonna take a pic of the fluid but I was just too covered in it.  The fluid didn't look bad to me, didn't smell burnt.  I'm not sure why it got hot, but I don't think it got as hot as my gauge said.  Maybe it was a combo of things, steep hill at low speeds, old fluid???  Not sure, but I ran it this weekend and its smooth as always.  I'm pulling my trailer up to buck creek this weekend, I'll give her hell on the way up and see what happens.  I did pull a hose off the tranny cooler outlet, and ran the motor.  It's definitely not plugged, pushed out about 5 quarts in 20 seconds, no kinked hoses.

Must be the gauge huh? Chevys are famous for their gauges going wonky? Electrical snafus?

My 2010 Colorados rpm gauge quit working at around 50,000 miles, soon after the engine temp gauge started to read inconsistently. Rather then buy a new gauge cluster for $900-$1500( depending on who you talk to) I bought a Scan Gauge II($200 ish) and have it plugged in and mounted below the AC controls so i can keep an eye on the engines temp.

Good luck

:yeah: I've had my cluster rebuilt on my 05 as it was doing weird stuff for a while. (like oil pressure gauge running the gamut.....0 to pegged speedometer losing 50 MPH at highway speeds.) Since there is a low oil pressure alert that was not going off I didn't go bonkers. No problem with the 07 yet

Look up how to clean your cooling stack. Maybe the cooler is plugged with bugs and debris and such blocking air flow. It's an issue on anything, but I think I've heard these trucks are more prone to this becoming an issue. Stuff accumulates between the cooler and the radiator and blocks air flow. Trans fluid goes through the radiator part of the radiator as well in that truck.

Post by: jackelope on July 11, 2022, 12:04:32 PM

No.
In terms of your fuel gauge, I'm saying that you should diagnose it rather than shotgunning a fuel pump or an instrument cluster at it.  It won't necessarily have codes and even if it does have codes, the check engine light is not always going to come on.

Regarding your transmission, I'd probably due the trans flush and the filters, and then I'd check and make sure the cooling system components are free of the debris buildup that blocks air flow as it seems to be an issue with these trucks, then I'd tow the trailer and see how it goes. I'll add that I would definitely flush it with a flush machine or another way of actually getting all the fluid out of everything. IF you're just draining what you can, you're not going to help it.

Gotcha!  The fuel pump is working fine, i was told it's most likely the fuel sending unit and that it's inside the fuel tank.  Not sure what's easier, taking the bed off or lowering the tank??  Thought about just cutting a hole in the bed of the truck above where the access is to the sending unit, then just tack weld or JB weld it back.  It's very intermittent, hasn't stopped working now for at least a year, of course now that I said that.....

Yep.
With a scan tool, you can see if the sender is working or if it's the cluster. It would suck to cut a hole in the bed of your truck and replace the sender only to find out that that's not what was wrong with it.

While I agree something seems amiss, 275-280 isnít gonna hurt anything for a few minutes pulling Chinook pass. Long term of course those temps will be detrimental.
Title: Re: 2006 duramax tranny getting hot???
Post by: MR5x5 on July 18, 2022, 12:08:58 PM
Generally speaking, tranny fluid would like to be at 170F.  Beyond that it's properties break down and are not recovered by lowering temperature, i.e. over temped fluid is permanently degraded.  The level of degradation increases exponentially with temperature.  The chart below is pretty typical regarding the effects of temperature on fluid.  Personally, I pull over if my tranny gets to 225F.  If it hit 275F I would be changing fluid at the next available opportunity.  A tranny fluid change is obviously way less money than a new tranny.



Title: Re: 2006 duramax tranny getting hot???
Post by: trophyhunt on July 18, 2022, 12:16:26 PM
I should look into after market gauges, I just don't trust the idiot stock ones.  I pulled it this weekend but only an hour away and no steep hills, it seem to do fine but the temp got to 250 if the gauge was correct, didn't even go over 200 on the way home.

Post by: trophyhunt on August 15, 2022, 11:03:58 AM
I have an edge ll, put it on the tranny fluid temp this weekend, also had a lazer heat gun to check the tranny itself. Gauges seems to be spot on, only pulled the trailer about 15 miles, slight short hills and my temp went up to 205.  Not sure what that means.  I have an appointment at Puyallup transmission Thursday to do a diagnosis.  Hopefully Iíll get some solid answers. Looks like I can get a brand new custom performance tranny for $3,000.  Thatís a relief, I thought a tranny would have cost me $10,000.

The thing for me is that transmission at that price sends my red flag radar in to overdrive. At a minimum I would be reading every review I could find. I also always encourage people to buy local if possible. If there is an issue at least there is someone you can look in the eye, not some joker clear across the country that says "no problem, just pull it out and send it back, we'll take a look at it".  :twocents:

Iíve worked at domestic dealership service departments pretty much my whole adult life. Almost 100% of the time the transmissions that are sold by the manufacturer(ford, Chrysler, GM) are remanufactured. Theyíre almost never new. Engines are the same.

I had the transmission in my 06 Expedition rebuilt by the trans tech in my shop and I spent almost $1000 just on parts, and that was replacing the parts that were bad along with an overhaul kit and a torque converter. I canít figure out how youíre buying an entire Allison for $3k.
Whatís the warranty on it and who pays labor if it fails? Make sure you read the fine print on that. Youíll have a warranty that covers $50 in labor per hour and youíre working with a shop thatís $150-200/hour.

Does this mean they want some remote trans fluid filter installed in your truck in order for them to honor the warranty?

I've replaced both filters, and the magnet was intact and clean, used fluid recommended and filters.  Hoping puyallup transmission come up with something other than an tranny replacement.  Not sure josh about that outer filter, I'm not going that route with that tranny, it looks good and cheap but I want to stay local.

Just talked to Ricky at Puyallup trans, what a great guy! He drove it around, had his scanner on it, looked at the fluids and listened to the info I have on it.  Bottom line, he thinks the tranny is fine, my fluid looks and smells good, torque converter had zero slip. He thinks maybe having old fluid in it that day it got hot and the fact it was a hot day pulling up the pass might had made it get warm.  He thinks Iím good to go, I might put a bigger pan on it the next fluid change, but I guess Iíll pull the trailer over to moose camp in Oct and see what happens.  Actually Iíll do a test run next weekend when we go camp at lake Silvia.  Iím gonna trust what heís saying, seems like a great guy, I guess time will tell.  I really appreciate ALL the info and ideas, now Iíll just run it till it breaks!! And hopefully get a few years out of it, certainly ainít spending 80k or more on a new truck!  He also said a new rebuilt by jasper for my truck would be about $6k, thatís better than 10k!

That's good news.
I was thinking that if there were issues with your tranny you would know it.

FYI regarding Jasper...
If there is a problem with a Jasper unit, the last time I dealt with them, they cover $50/hour of the labor and they require the unit to be removed and sent back to them for repairs. No in-house repair. It takes a while for shipping back, repair, ship it back to the shop and have them re-install it. It may have changed as it's been a while. Just something to make note of going in if you have to go that way.

if you are a preferred jasper dealer they pay more labor and also allow in house repairs, in most cases they ship a new unit out immediately. the reason we sell jasper is we rarely have the need to use their warranty.

Well, took the trailer to silvia lake state park last weekend, not any real big hills but everything went very well.  The hottest my tranny got was 206, most the time it ran around 150-160, on the way home, less hills, cruise control set at 60 ish, it ran a lot at 140!!!!  I'm pretty confident my tranny is ok, and my problem was old fluid and filters needed replacing.
