Walked home (lucky only 2 blocks at -15 it was cold). Had GM tow it in and have check in the am at the dealer.

Bigwave,

Have your dealership check the transmission cooler lines. I've seen a few where they were kinked preventing cooler flow resulting in the transmission overheating.

If fluid was pouring out wouldnt that mean a cooler line burst/broke and the trans smply ran itself without fluid, causing it to burn up?

the guage wouldnt show the temp?

If fluid isn't flowing through the cooler lines than that fluid just keeps getting churned in the converter until it gets really hot and the seals fail. Unless that hot oil gets back to the pan the temp sensor won't pick it up.

It was never stated where the fluid was coming from. Could of been a ruptured cooler line or could have been from the breather. There's alot of places that the fluid could leak from.

Mine did this @ about 25K. Line installed from factory wrong. Lost all my fluid in seconds. luckily my line popped 100 yards from my house on my way home. I pulled into my driveway and it looked like it was gut shot. Walked down the street to find a six inch wide stripe 100 yards long. When I took it to the shop they accused me of having the front end worked on like a lift or something. They told me the line had been moved. Sorry, that was not possible. The only thing that had been done to it was oil and fuel filter and that was done by them. The trans lines were ran all wrong. I would have thought the oil change techs would have noticed this, but they didn't. I would encourage every D Max owner to compare his lines to other trucks to see if they look similar, if they do not you are driving a time bomb. This has not happened to a ton of people, but it has happened to some others on here. This is not an Allison problem this is a Chevrolet problem. I had the truck back in 3 days. My tranny was fine. If you want to talk about it PM me & I'll give you my phone #

Good luck, Scott

New Trany

Got The new trany in. The other sounds like the Torque Converter was fried and much of the trany. Seams like the extreme cold has something to do with it. Dealer has ordered the new transynd at putting in. All under warrenty. I think I got the best dealer in Wisconsin. (Bergstrom).
