I have a 1989 300E Euro version with a 5 speed manual. The transmission needs to be replaced, or possibly rebuilt, but these are not available in the US as far as I can tell. I was wondering if a 5 speed from a 190E 2.6 would work. That seems to be the only 5 speed imported in large numbers. Also, if anyone could point me to a guide for what the part numbers mean, that would be helpful as well. The number relayed to me by my nechanic on this on is 126 260 17 01 717 433. I think I have the first few figured out, but not all of them.

Any help would be appreciated.
