<html><body>I feel the next step is to remove the solenoid cover and clean the non return valve, check that it is not damaged-seat the ball and have a look at the accumulator piston and bore. How well was the solenoid adjusted to go into and out of OD-binding of shaft or smooth operation and proper adjustment? If you reversed the car with the OD engaged, the clutch in the annulus is probably damaged and thrust ring broken which will warrant a tear down.

<div>My next step would be to fit a pressure gauge to
determine if the problem is due to residual pressure or the clutch
sticking (something I have never encountered).

have a issue with the overdrive not disengaging and becoming stuck
in OD after disengaging, it’s not an electrical issue and we
have to rock the car back and forth until we hear the clutch pop
loose and off we go until I engage it again and then try to
disengage it , I have pulled the operating valve and cleaned real
good the tiny hole in the shaft and have drilled it out one size
bigger as directed by a Healey restorer , to no avail.<br>
Any helpful hints ?<br><br>
