I've finally tracked down the source of the leak in the transmission of my 300E. It is comming from a large (1.5") cap with 12mm Allen on the side. It is on drivers side forward of the linkage.

My question:
Can I remove this cap and replace the gasket or o-ring without disturbing the internals?

Also, I bought this car used and, per the pan gasket I replaced, the benz parts guy thought someone had put a 400e tranny in the car. Didn't know that was possible but that's what he said.

All help greatly appreciated.
