There is a thread on here some where that talks about the cut over from zf built to chysler built for the 8hp70s.
The plot thickens...will be interesting to see if more 2015's start having transmission issues with 8HP70's but the only two I know of with identical symptoms and leading to early replacement were both SRT's.

Also, apologies I've totally derailed a 9-speed KL thread...I'll bow out.

Re: Heads Up: New transmission update as of 02/02/15

I have a March 2014 built TH and have had no issues what's so ever with the transmission (did have one flash done, did not notice any change since I had no complaints to begin with) until last week with nearly 11,000 miles on the clock and I got the dreaded "service transmission" warning and check engine light came on. It went into limp mode but I made it to where I was having dinner. came out after dinner (very cold night, like 4 degrees) and started it up and warning was off and all shifted perfectly. check engine light stayed on. took in to my great dealer Foss Motors, Exeter, NH, Sat. morning and they took it in immediately and re-flashed tranny with what I assume the newest flash. Service manager assured me I would not have any issues since the fault code was in fact for software error. I have put nearly 700 miles on the TH now with no issues at all. I wish Sergio would just come out with a blanket lifetime warranty on these transmissions and call it a day. I love the car, it is more than I ever expected! I just worry that tranny issues may come again in the future?

I'm passing 3,000 miles with my Oct 2014 built Trailhawk. After the first 500-1000 miles everything was smooth sailing. Hopefully I don't end up having any issues down the line with the potential "shavings".

There's also talk about a c-clip failure in some transmissions. But at this point, it's all hearsay.

•The TCM and PCM must be reprogrammed with new software.
•No parts are required to perform this service procedure*.

@Milous - Have you seen TSB 21-008-15 REV. A (RRT 15-006) yet? I believe it was published 2/7/15.
