I am rebuilding my MGTD transmission-on assembling it I notice that the selector shaft that the reverse gear selector fork slides on is open to the rear of the gearbox case. It it hollow with a threaded end for a possible plug (the factory schematic shows a plug listed). But my gearbox has no plug, and I don't think the shaft has an oil passageway that goes anywhere. See picture attached. Can I leave this shaft open w/o a plug or must I make one up?
Answer Hi Ken.
The shaft does require a plug, so you will have to make one. The original plug was just a grub screw with a slot for a screwdriver. Please note that the thread is fine metric 8x1 mm, as are all the studs, nuts and bolts on this gearbox. Even the gear knob has the same pre-war French metric thread.

Thank you very much for the information. I will make a grub screw type plug as you suggested. Ken
