Where is the torque converter lock out switch on a Beretta '92 3 1 engine?

This is the plug and not the switch....The switch inself is located within the transmission.


If the car has a 3spd automatic (TH125) Look on the front (closest to the radiator) driver side of the tranny for a 4 prong plug...this is the TCC plug....

Unplug it and drive the car. If the problem goes away, then you can replace the solenoid or drive it with it unplugged...it WON'T HURT THE TRANNY!! You will suffer on mileage though.
