Hi, new to this board and looking for advise! My 92 Accord EX-R auto trans torque converter wont stay locked up during a freeway cruise (4th gear, engine warm, light throttle, 60-70 mph). Have tried numerous good used parts, including:
transmission, transmission control module, engine control module, throttle position sensor, coolant temp sensor, interlock control unit. I am certain it is not a mechanical problem but something electrical instead because when the converter unlocks the electrical signal disappears. This is the signal from the tranny computer to the lock-up solenoids ot the top of the trans. Somebody else must have had this problem before, Help!
