Add mine to the list of still on original tranny but issues. Started right at about 50k (changed fluid in mid 40k miles). I am at 60k miles now. Mine shudders, clunks when downshifting, and will rev and slam/clunk when at a stop sometimes. The third issue I wish would get worse and then I will take to dealer for warranty. After I get it replaced I will be getting shift kit and cooler asap
My car has shudders since 20k miles. Wife drives it mostly and the car has seen a lot of highway miles. I drive it hard here and there and use to use the tap shift a lot but the way it shifts its no fun to use anymore. I plan on keeping the car a long while so I am sure eventually TEP will get some of my business

Hopefully, you can get it taken care of while still under warranty..Just don't wait too long!

I had a transmission go at about 56,000KM. The first dealer I brought it to the ******* had my warranty blocked because he said after market parts f@cked up my transmission. Brought it to another dealer and they warrantied the transmission before GM could post the previous notes. I wonder if GM sent out this mass recall what they would do with A hole dealers trying to block warranty on the **** *** transmissions.

It's good you found a dealer that took care of you. It's just a shame that the replacement tranny has the same flaws as the original.

You may want to file this issue with GM and the NHTSA as described on this thread:

For the record, mine was a rental with ~10k on it when I bought it. The first trans went due to a faulty TCM, I kept beating it even though it was malfunctioning, the flush didn't help either. This factory rebuilt worried me a little bit, but it's perfectly fine.
There are 80K+ LS4 powered vehicles on the road.
And you can take gxp-miller off that list, there is nothing wrong with his transmission. How many other names are on there that shouldn't be? You have single-handedly ruined this forum for me, just so you know. I've put up with a lot of flack about my car and you're the one to run me off. Congratulations, I'm gone like Mike.

You can go ahead and add me to the problem category.
Mine shudders really bad at WOT on the 1-2 shift. I seriously doubt it's wheel hopping so seems to be something internal.
Works fine any other time though.
2005 GP GXP with 71,000 miles. Fluid is cherry red and smells fine and I have a tranny cooler.
