Tranny replaced, now jacks system wont work?

Question

I've had my 34" Pace Arrow Vision for 2 years. 1996, 49K. Last year I had the tranny replaced (454 Chevy engine, DL480E tranny). From the moment I picked it up from the mechanic, the jack motor ran constantly and the jack system would not work. I did not realize the new sound I was hearing was the jack motor until it hemoraged red fluid everywhere after a 30 mile trip. Mechanic met me at my location, ran it up on ramps (Very dicey and dangerous, but worked) and pulled a fuse from the jack motor, making it stop.

I am interested in having the jack system repaired this summer, as I am not handy enough to tackle it myself. My question: The jack motor still tries to come on intermittently (despite my having disconnected two wires I found going to it). Is it safe to go on a few trips before I take it to a shop? Will anything else be harmed? Im OK with not having use of the jacks. thank you for your time!

If you disconnected the correct or all the wires and properly isolated them from touching metal/ground, it could NOT come on.

Specifically, remove the fuse to the large gauge positive wire OR remove the positive wire from the jack motor and isolate it-- sticking it inside an old rubber hose will work.

If you are asking us to speculate on when it will next "auto-start" .................

I would venture a guess, your mechanic broke / disconnected a wire from one jack that tells the system that the jack is fully retracted. So the controller believes it needs to retract a jack. and runs all the time.

shouldn't be a hard fix, but it will drive ya nuts finding the wire.

You need to state BRAND of jack system. Powergear type systems from 20 years ago, the Pump motor would activate when it saw the gear Shift come out of park and the parking brake was released. But, that control is NOT anything ON the actual Transmission. Dropping a Transmission and rebuild and reinstall should not have caused a problem with the Jack system. Unless he had to mess with the Chevy Auto Lock system for the Transmission release at the Dash Steering column. Doug

I do know from experience with my Power Gear setup that allowing the motor to continuously run caused my entire dash to flip out when the motor finally burned up.

Disconnect the power and ground to the motor & as said, isolate the ends so they don’t touch anything.
