beretta tcc

i have a 90 beretta 3.1 with the common stuck tcc solenoid. i've had the connector unplugged for about 6 mons. but its hurting the mileage (of course) the car is a $400 work car that i don't want to put $ into. has anyone ever "switched" the tcc sol. wiring? i was thinking it wouldn't be to hard to toggle switch one of the 4 wires, just don't know which one to switch, if it's even possible. not much of a tranny guy, just wondering if it's even possible

I'm not much of a tranny guy, either, but I don't think you are going to be able to do a work-around. Have to wait and see if anyone chimes in. Next time I'm in my favorite tranny shop I'll pose the question.

More than likely the TCC solenoid is bad. Why not just change the solenoid? Not a bad job, have to drop the trans pan, loosen 1 bolt that holds the solenoid in place and route wires thru existing wire supports and out side of casing. Worst part of job is dropping the pan - change filter while your at it.

Your stuck TCC solenoid, is it keeping the TCC stuck on? If so Wiring a by-pass switch won't do any good. A stuck on TCC will cause the vehicle to stall a stops and it's sometimes hard to start. Replacing the TCC solenoid it's too hard, it's under the side cover of your trans.
