My 3-rail gearbox has been leaking for years, and I
have not been able to completely eliminate the
problem. It leaves a little puddle of gear oil on my
garage floor.
The engine, on the other had, hardly leaks at all.
I did do one non-obvious fix that reduced the leaking:
I replaced the O-ring seals where the three shifter
rails pass through holes in the front of the gearbox
cover.
