Bruce Kennedy (user here) and I picked up a 1985 300sd from Peoria, Illinois over thanksgiving break. He needed the engine, and I the transmission.

Long story short, I'm putting the transmission from this parts car into my car.

So, what needs done while its out of the car?

I planned on replacing the fluid (with some synthetic) the filter the pan gasket and clean it up. I also plan to do the flex discs, and the transmission cooler lines.

Should I do the K1 spring kit while it is out?

What about the BX pistons? They're cheap, should I do them now?

Is there seals that I should replace since it would be easier to do when out? Front seal?

Can I get all this from Phil at fastlane?

Thank you for any help.
