Hello, I am wondering what this statement is all about? I have two transmissions in the garage right now. They both came out of two different cars but they were both the same model....1988 420 sel.

These are the part numbers stamped on each:
1- 126 270 05 00 722.324 0 308 1840 (This one mated to a 2:47 open diff) (car manufactured 09/88) 249,598 kms.
2- 126 270 29 00 722.355 0 314 2293 (car manufactured 03/88)

So...now that I read this thread I am wondering which one to use?
These transmissions look identical from the outside. What has been upgraded on this 722.355 compared to the 722.324?
I was told by the dealership parts guy that the relevent part numbers where just 722.3 and it stopped at that making these transmissions exactly the same. Odd since they are out of the same year of car...so what is different?
The 722.355 is the one I have decided to use as it looks abit cleaner. The 722.355 I have actually seen working as we drove the car. The other (722.324) reportedly works although I have not seen it myself....the car was stripped due to a failed timing chain.
