Since we are on the subject, if I were to replace the 4-speed manual tranny with a rebuilt W116 4-speed automatic (more easily obtained at the Merc graveyard here), what additional modifications/additions would be needed?
W116 280SE Euro (screamin' at >80mph)

You would need all of shifter, linkage, & front half of driveshaft to install 5-speed. The trans support is different also. With the 5-speed having an overdrive 5th gear the engine will be turning a lot less rpm on highway.<HR></BLOCKQUOTE>
