Tranny Quest (722.) Please Help.

[DaveL]

Ok, so I am about to pick up my 500sel with newly rebuilt tranny. Quick background - after shopping around for a month and finding prices from $4500 (dealer) to $2600 (most indy's), I found a guy who does MB auto tranny ONLY, and he quoted the entire job (R&I tranny, full internal rebuild) at $1200. During the rebuild, he suggested resealing the back of the motor ($25), and replacing the flex disc ($125), and I opted to do both.

The tech called me this morning and said that the tranny is in the car, and works properly. HOWEVER - there is an electrical problem in the kickdown system, and this causes it to shift funny (or not at all...). He says that if you disconnect the electric control and rely on just the hyudraulic control, then the car drives fine (shifting properly including downshifts). He said that the kickdown selection was not as precise as it should be (with the electric disconnected), but it could be fine to run it this way for quite awhile without problems.

Of course, I am certainly concerned that the tech didn't report that the rebuild went fine and everything was working great. He is certainly implying that the tranny is fine (rebuilt properly), and this electric problem is secondary (meaning not included in the cost or process of a normal tranny rebuild).

The tech is going to call back with a price on the electric parts needed.

Thoughts? Experiences?
