As part of my spring cleaning I decided to remove the sump plate
on the overdrive unit of my '78 MGB. Beside an acceptable amount
of "shwarf" there was also 3 pieces of what I have come to identify
as a thrust washer for the LH overdrive. At least I think that's
what it is...about 1.25" in diameter with notches cut at all four
corners (of a circle !) My question is, what exactly does this part
do and when can I expect to have to re-build ? The gearbox and
overdrive appear to suffering no ill effects in the absence of this
part, although I have noticed an occasional grind when reversing
with a cold engine/gearbox.
Thanks,
Andy McLean ('78 MGB)
