We have a motorhome built on an Econoline, with a V-10. 1999, 17,000 miles.
This morning, it wouldn't move. Felt like it was in 4th gear at a dead stop. We got the following codes:
P0743 Torque convertor clutch system electrical
P0750 Shift solenoid A
P0755 Shift solenoid B
P1747 Pressure control solenoid A short
I learn a lot by visiting here, and would appreciate any help. Not sure where to start on this one, although it sounds like the tran is not getting the electrical signals it needs.
Originally posted by tmadine Further investigation revealed that an animal had chewed through a wiring harness. That'll do it!
Even better, I was investigating a rattle in my '01, and found the two wiring harnesses that pass down the driver's side of the chassis were pinched FLAT between the chassis and the cab. Guess what? One of them was the tranny control harness. Would have been fun to have have it start shorting to ground, eh?
