    Crazy transmissionn temps

    I got the old trans out last night. The TC looks like it has been HOT! It is very dark in color and the fluid smells horrible. This is new fluid that I just flushed out and replaced less than 100 miles ago. Fingers crossed that this used one holds up. (I know that i should have gone with a...

    Crazy transmissionn temps

    I've got the old trans out and the used one ready to go in. Hopefully I'll have it done by early afternoon. Will I need to have it programmed at the dealer or by someone with the GM software?

    Crazy transmissionn temps

    @NickTransmissions Does this sound like the likely culprit - that the TC has crapped out and will not lock up thus causing higher temps? There are no restrictions in flow and the fluid level is fine, and the trans itself shifts and behaves as it should. It's just that the temps climb and climb...

    That's a good idea. I do have a temp gun. I'll try that this afternoon

    Crazy transmissionn temps

    Thanks. I'm pretty sure this is all original factory equipment. The hose routing is a it should be. The story of the non-locking up TC is so far the best fit scenario. Trans still shifts and runs like it should but the temps just keep on climbing until I shut it down

    Are there threads on here detailing how to do that?

    I found a trans and 6.2 out of an escalade with 157k miles. Any reason why the escalade setup wouldn't work the same way?

    Crazy transmissionn temps

    I just talked to a transmission shop and got some advice/bad news. I just realized that I have never listed the mileage for this vehicle - it's at 239k. Anyway, after going through the story with the shop owner he thought it sounded like a torque convertor failing. He said that if it drives and...

    A quick search just showed me that there are in fact a ton of options available for an aftermarket cooler, many less than $100. Who here has had experience with them? Good, bad, no change?

    Crazy transmissionn temps

    I have an inexpensive one from car parts.com if I remember correctly. No idea what sort of heat exchanger is in there but I know I don't have a clog as I was able to flush most all the fluid out through the top side fitting. Is there an external cooler I can install similar to bullet proof...

    Crazy transmissionn temps

    My 2011 5.3L has experienced some CRAZY temp issues lately. On a trip to the 4 corners area i decided to check the trans temps just out of curiosity because I was bored on the long drives and 100 degree outside temps. Anyway, I saw elevated temps over 200 so I monitored for the rest of the...

    Humming only in auto mode only on deceleration

    I have a 2011 Yukon XL, stock everything, and have recently noticed a humming sound that seems to be coming fromn the front driver's side area. It only happens in auto mode, and only on deceleration. I haven't been able to spend the time diagnosing much yet but we will have a lift installed...
