I'm considering purchasing a 93 300d 2.5 turbo. My concern is that the tranny has a bad reverse. Takes a few seconds to engage and then slips badly for a second until engages and chirps the tires. Don't know much, but know that can't be good. A friend has a good 722.414 that came from a 89 201. He believes it is a suitable replacement for the tranny in the 93. Can anyone tell me if this is so?

Thanks for all your help.
