You might find a T-350-C. That is the lockup converter model. It is identified by an electrical connector right by the shifter shaft. It came in my 83' wagon and after I yanked the computer I hooked it up with a toggle switch on the dash so I could engage the lockup on the highway. You could see a 500 rpm difference at highway speed.
