Torque converter won't lock up
Hey guys just bought another 94 cummins bone stock 146,xxx miles. Truck runs awesome shifts great and rides smooth. But the torque converter is not locking up with the over drive on or off. I cleaned grounds and checked a few thing but not sure where to really look. Was also wondering if putting a lock out switch would fix the issue or if it wouldn't work at all. Any advise would be greatly appreciated.

We'll I'm not sure when it was last serviced I do plan on doin it. The truck did sit almost 2 years before I got it. But the tranny fluid is clean and does not have a burnt smell. So I kinda think it is some sort of solenoid. But I don't know where to look for that. Would a lock out switch work or would it do nothing

I am not being smart, but have you checked the wiring to the transmission? Make sure the wires are good and make sure the switch is actually plugged in properly. Trust me from experience here, a wire that looks good can be broken inside the casing and look good. Never assume before you have checked. If I am not mistaken the plug you are after is on the Drivers side of the transmission and really open to the crap under there.
