I have a 74 MG Midget that has a midget 1500 engine in it. It also has a Laycock type J overdrive in it. I am wondering where the gearbox came from and what year? On the side of the gearbox it has a cast marking of 22G1553 (but that could be just a casting part number). Any help?
Why I am asking this is that I want to find out what type of oil is needed in the gearbox.
