Wow, thanks everybody!  Lots of good info and suggestions.  I have a few
things to try out and will report back.  I am at Road America this weekend
with Midwestern Council and will see what happens.  If I can't get it to work
I'll have to R&R it before the KasCup.

Subject: [Fot] J-type overdrive reluctant to disengage

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.
