[Healeys] Overdrive solenoid

[PG]

I've had a problem with a "weak" solenoid where it wouldn't hold.  I
replaced it with one I had kicking around and everything was fine..  So, I
can't tell you where to buy one...sorry.

If not the solenoid, it could be the pump which can be checked with a
pressure guage.....bit of a hassle.   I would assume the solenoid first.

Up to the mark with Redline MT90 which I have used for  fe years now with no
issues.
