Sooo im forever trying to get me car back up and running so Long story short. I bought a 95' S500 that didnt have reverse but did have the FWD gears. I re-freshen my motor and rebuilt my tranny. Now the car has reverse and goes into gear but does not want to shift gears. Pretty much stuck on 1 gear when driving. So my dad was saying its the torque convertor is bad. So now we have a spare w126 motor and tranny that we pulled out of a 420SEL. I was wondering will the w126 torque convertor work with my w140 tranny?
