After doing some of the testing outlined in the above mentioned article, it appears that the solenoid is not functioning. When battery voltage is applied to the #4 terminal and the a ground is applied to the case, the expected (hoped for ) "clunk " does not occur. My question is,until I have a working solenoid, is there any concern about driving with the OD cable pushed in and the transmission continuing to freewheel? The car is actually more pleasant to drive when the engine's RPM's are allowed to drop when not accelerating. The gearing with the OD rear end is such that the RPM at 45-50 make the engine sound like it needs that other gear included in the Borg Warner OD. On the other hand, I don't want to do any harm to the transmission by keeping the mechanical part of the OD setup in use if it is not advisable. Thank you for any advice that may be offered.
