[Healeys] Transmission / Overdrive or Clutch slippage

[David Porter]

A couple possibilities... low OD pump pressure, binding OD springs, wrong lubricant..these will cause "free wheeling"

Worn OD-clutch?

Hi all,

We are suffering what seems to be strange transmission / overdrive problem or clutch slippage.

A few months ago, we finished restoring my 1962 Tricarb BT7. Before the restoration the  overdrive was operational. 

On initial test runs, the car run fine but the overdrive did not work. On further tests and suddenly, when disengaging the clutch on any gear, the car revved but didn´t move. No smell of burning clutch, just slippage 

The transmission and clutch were removed from the car. The clutch was redone, adjusted and tested. 

Problem momentarily solved but overdrive still nonoperational. After further tests the same slippage problem appeared again. Transmission and clutch were removed, revised and installed. The seals on the overdrive were changed but my mechanic preferred to temporarily disconnect it (electricity cut off).

Problem solved…momentarily. Now when engaging second gear, the RPMs drop a little like if the overdrive activates even though is disconnected (this only happens in second gear). After driving a few miles we get the same slippage (the engine revs but car won´t move) only when engaging reverse. If the engine is turned off and then on, then reverse works.

Any thoughts?

Thanks, 

Rafael
