Hey people. I looked through the archives for this, couldn't exactly deduce the answer. I have a 1983 240D with automatic here in Hawaii. I got a line on a manual 240D (rust bucket/not running) As a donor car that is not a problem, but what I would like to know is are all 123 240D's compatible with each other. Also,since I can't test drive the donor, what is best way to survey transmission? My car is great (body excellent w/118K miles) but I can't help thinking that the manual trans is a better match for this vehicle. Thanks
