Hi,
After 460000km my 1981 380SE have developed som transmission problems. First, it slips between 2. and 3. gear when accelerating slowly or moderately (but not hard). Second, in reverse, it moves but feels like the brakes are on (not a problem when the car is cold). I have tried changing oil and filter but to no avail. Any clues?
Rather than investigating in an expensive repair I think maybe I will swap the transmission with another W126. There seems to be different transmission versions (mine is a 722.301): are they interchangable? Specifically, should I be able to use one from a
1988 500SEC in my car?pej
