No 3-speed Torqueflite has electrical lockup, only the OD trans has it.
The electrical connection on some late 904/999 is to unlock the converter only.
John what do you mean unlock only ? Heck my 88 pick-up had the 3 speed with the lock-up but they do call the relay the Part throttle unlock relay. Course how can you unlock it without it having a lock-up converter ?
