Dear Friends,

I can't find the 'filler plug' to top up my SD1 Rover LT77 gearbox.

See attached link which explains it all...

The filler plug is on the opposite side of the transmission, but towards the rear of the transmission on the aluminum tail section of the gear box about 3-inches up from the bottom. Same size as the drain plug.
