[Healeys] slipping clutch vs. slipping OD

[warthodson at aol.com]

At a recent club meeting a member indicated that he thought that his 100
clutch was slipping. But he also said it might be his overdrive slipping. Of
course, the car was not there so we could not verify anything. Here are a few
of the questions that arose:
1. Can resurfacing the flywheel cause the
clutch/pressure plate assembly to not fully engage & result in the clutch
slipping?
2. Can an overdrive slip? Assuming the answer is "Yes" can it slip
both in overdrive & out of overdrive?
3. I understand that a new clutch disc
has been installed recently. Besides oil on the clutch disc what are some of
the other possible explanations for clutch slip?
