Hi Bob,

Speculatively replacing parts is great when the process is easy + quick and parts cost is low. I'd definitely try to isolate the problem before disassembling tranny mounts and even before removing the OD solenoid by any method.

1) check + clean the fuse and fuse holder contacts. I twirl a small knife blade in the fuse holder holes, that's the contact surface there.

2) check OD wire where it exits the shift lever housing into the tranny tunnel, and as it drops down the side of the tunnel and heads forward. This is on the right side of tranny tunnel. Wire likes to disintegrate there. PITA to repair if you're lying on your back; I can give you some tips if that's the problem.

3) check your bypass of the OD relay - just to make sure a connector didn't slip off or some such. If it's easier, you can check for voltage (ign. on) in the OD wire as it passes thru the shift lever housing.
