![]() Unfortunately, the transmission in this car must come out to get the valve body out. There is a regualator valve inside of the valve body in the tranmission. ![]() RE: Controlling torque converter lockup Metalguy (Materials) 15 Jul 03 04:22 There are no codes and the torque converter clutch circuit is functioning properly. It seems to happen on curves as well, like on entrance or exit ramps. It returns on hills under load (a steady lope). It usually happens right after shifting into high gear (1500 to 1800 RPMS) and then clears up at cruising speed. From what I have read, it should lock in at a minimum speed of about 45 mph. I noticed this when I had the test light attached. The torque converter will lock-in around 30 mph hour in the car. I have searched for leaks previously though. It may be a problem that results due to to heat and vacuum loss. There is a vacuum modulator on the transmission, but I don't think those go bad too often. ![]() If it is the regulator valve, the hydraulic pressure should change when the surging takes place. I have heard that there is a hydraulic pressure test that can be performed to confirm or disprove a faulty regulator valve in the valve body. Since this will be mounted in the engine bay, it will probably be easiest to pull your +12 from the coil, then go to the vacuum switch, then to the trans RE: Controlling torque converter lockup Smith231 (Agricultural) 9 Jul 03 19:09 I know for a fact some early 80's trucks have them, and pretty much any car that had a 700 but WASN'T EFI will have one. This is also very easy to find in the yards. Something else that is recommended is a vacuum switch. Run the ground first through a brake switch (just about any car or truck in a junkyard that had a 700 will have one), then through a lighted SPST dash switch (electronics store), then to ground. I suppose you could go constant hot, but there's no real good reason to do so, and a couple reasons not to. Then, give one pin +12ignition (hot in run or start). You'll be able to trace the two wires whe you rebuild it to figure out which two pins in the 4-pin connector that you'll need. The device that controls converter lockup is just a solenoid.
