Give your local dealership a call and ask one of the technicians, but be sure to have your VIN number handy, as they will ask for a certain portion of the number. I did exactly that myself for my 1989 Buick Century, and the technician ran my VIN to find out what type of transmission was installed at the factory.

Does a 1988 Chevrolet Cavalier have a lock up torque converter?

Yes, both the Iron Duke 2.5L engines and X-VIN 2.8L engines have lockup torque converters. The 2.5L engine was equiped with a TH125 transmission that had a 3 speed + lockup TCC, and the 2.8L engine was equipped with a 440T4 transmission that had a 4 speed + lockup TCC, being much stronger than the former.

What kind of transmission you need if you swap a small 8 cylinder engine in a fiero?

You will need front wheel drive transmission. If you want a manual transmission, the most popular is the 5 speed Muncie/Getrag that came stock in the Fieros. This transmission is supposedly rated to 400 horse power. If you want an automatic, that REALLY depends on the engine as many automatics are electronic and require the engine computer to control the shifting. The most popular transmissions in this group include 4T60E, 4T65, 4T85. Non-electronic transmissions capable of running small V-8s include the stock TH125 and the 4T60 (non-"E").

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 WON'T HURT THE TRANNY!! You will suffer on mileage though.
