[Fot] J-type overdrive reluctant to disengage

[Barr, Scott]

So I have my new J-type overdrive trans in the Spit and took it out down the back road near my house tonight.  The overdrive engages and sometimes disengages.  But a lot of the time it remains in overdrive despite flipping the switch off.

The trouble shooting section of the manual lists several possible causes (none of which I like because they sound like removal of the trans).  Sticking solenoid, sticking cone clutch, clogged control orifice, faulty wiring.

I wouldn't think wiring is the issue if it works right some of the time.  Any chance this relates to running it at lower revs than I would on track?

Freshly rebuilt box from Quantum Mechanics, John Esposito.
