could be electronics could be converter. if your thinking swap just build the auto and be done. a good triple disc converter and a suncoast valve body you will be very happy.

A Snap on scanner will tell you if the tcc solenoid is activated by the computer. if the solenoid & valve are ok pretty shure the lock up clutch is no good. How many miles are it?

if the clutch was going out it would shake and shutter like crazy before it wouldnt lock up at all.
