My Dear Benz Brethren,

What are the differences between 300D & 300SD transmissions? I'm buying a 1985 300SD parts car with a bad tranny - but it's maybe too good for a parts car. I have a 1985 300D parts car with a good tranny. I think that I've read that they're the same except for rear of the tranny (but I can't find the post - Argh! ).

Can I make my 300D tranny into a 300SD tranny? Thanks!
