Thanks Tom.. I have downloaded your articles and will be studying them..



Is it true that the OD will freewheel when downhill, and you should shift out of OD before coming down a steep grade?

I am thinking if I can go up some of these hills with the car in 2nd and overdrive, I should be able to run 35-40 and not lug the motor, but then would need to shift out of OD at the top of the hill to have gears to hold the car back on the downhill.

Does the cable engage/disengage the OD into the system? (or lock the OD out)
What does the Solenoid do? The same thing?

So to engage, I would have to move the lever/cable into the right position, and then turn on the solenoid electrically to engage the OD into service, and then turn off the OD electrically to get back to normal drive (and have gears for downhill cruising).

The lever and cable should be moved to disable when reversing?
I'm just wondering how one operates these sort of OD's and if they can be used as a gear splitter if the speed control solenoid is not used?
