Hi all!

I plan on changing my ATF on my automatic '83 245. I don't have the Owner's manual with me, but I remember it states that the fluid requirement is something other than ATF; it is a 3-letter abbreviation. Does my wagon use a special fluid? Or regular ATF will do?

One thing I'm concerned about is what may happen if I change my fluid. Right now, it seems to shift smoothly, and the fluid looks pinkish and "healthy." The car does seem to make a clunk-like sound followed by a jerk when I shift from "P" to "R" when cold. Other than that, all seems fine. Anyhow, should I change the fluid; I bought this car recently, so I kind of want to change the auto fluid just so I know where it stands.

BTW, I also plan on bringing up the OD problem to the mechanic. Is there anything I should know before I get talked into spending $$$ on something that could be really cheap to fix? I think my OD problem is more electrical than mechanical, is that an easy, CHEAP fix? Thanks.
