Randall,
What should the operating pressure be? I understand that if you attached a
gauge to the overdrive unit, you can measure the pressure.
My overdrive works fine in 3rd & 4th and quick to engage, but seems a little
slow to engage at the higher RPMs in second gear.
If the pressure is down, is it the sealing o ring where the gauge goes that
may be leaking off some pressure?
Regards,
Ibsen

It's primitive, but not quite THAT primitive!
Still, it's embarrassing (and not so good for the OD) to catch 2nd gear and
have the OD try to engage immediately. Mine leaked internally enough that
it wouldn't have pressure up by the end of 1st gear, so it would sort of
hang between 2nd direct and 2nd OD, with the OD clutch slipping.
