Crosley, I rechecked the circuitry, Everthing checked out. I went ahead and replaced the solinoid. I wired a direct ground to pin 4 and switched 12vdc to pin A. This eliminated the 4th. gear pressure switch. You could hear the solinoid energize when the engine wasn't running and the switch was turned on. When I went out for a test drive the only time the converter would attempt to lock up would be around 40-45mph, 1900rpm. In order to get it to lock up I would have to level out the acceleration or let up on the throttle. Then it would it would not stay locked up, it would go in and out. If I depressed on the throttle it would stay unlocked. It didn't matter if the fluid was hot or cold.
What do you think.
I appreciate your replys.
