123k on my 1997 S500 Sedan.

Funny though....soon as it hit 120k my tranny took a massive dump. This was back in November '04...I decided to take it to an indipendent "shop" instead of a reputible mechanic....needless to say $4300, 2weeks waiting on a valve-body to be delivered and now 2 months later, I still do NOT have my 140 back and I'm thoroughly pissed. They have completely rebuilt my tranny and the latest is that I now need to replace my TCU (tranny control unit) which is $1200 including dealer reprogramming...

For anyone out there having trouble with their 722.6...do yourself a HUGE favor and GO TO THE DEALER!!!! Sure you'll spend more $$$, but it'll be worth it
