32rh problems

[Mpagss]

I have a 97 tj. Love the jeep rebuilt most of it since I’ve had. Anyway I have the 3 speed auto in it. It was old and worn when I bought the jeep and there after it was blown and then rebuilt. Got it back and everything was a little messed up but finally got it figured out. Fast forward a year later and yet again I’ve lost the torque converter lock up just like the first time. Not sure on what I should do with this tranny. Is there anything that could cause this loss of the lock up or can my tranny be blown again. Please help me out if you can. Thanks

The PCM grounds the negative side of the torque converter's lockup solenoid to engage it. You might try installing a temporary on-off switch to manually provide that ground when you're at cruising speed to see if it engages. If it does you either have a wiring, connector, or PCM problem. If the Overdrive still doesn't engage at least you have confirmed the issue is in the transmission.

How exactly is a temporary switch installed. What will I need to get that done? Thanks
