I'm looking to swap a tranny from the junkyard for my 300sdl. I need to know what my options are for a direct replacement.
Here's what I know so far:

Model: 722.3xx

Pre -86 diesels - No
420SEL - No
300E up to 1991 - Maybe

Can someone tell me which other models are compatible. Will an '89 300SEL work?

Thank you.
