how to unplug tcc solenoid

I hadn't considered that lockup removes the work that the fluid does to multiply torque. If it malfunctions, the vehicle stalls when you slow down for a stop or a turn because the torque converter stays locked in overdrive. Once we have let it sit for awhile, it will go again. When you say you tried everything, did "everything" include a bottle of lubeguard or equivalent friction modifier? I dont thing a programming update will correct. We can do the work ourselves, but at that price, we might just have someone else do it. I have never bought that assunption and the gas mileage will not suffer much because the converter doesn’t lock up anyway until you reach cruising speed, and most cars would perform better if it didn’t. Now, lets unplug that lockup solenoid. When the SeaFoam didn’t free up the TCC solenoid, I would unplug the TCC solenoid to prevent the stalling problem. 01SilverFire is right on with the location of the electrical connector. I still might just pull the wires, and drive it like that. There is a solenoid in your GM converter that causes the the torque convertor clutch (TCC) to engage and disengage. Thanks, actually what you said makes tons of sense! The torque converter clutch is part of the converter. Won’t harm a thing. How do I test my torque converter? Right behind the drivers side front wheel you will see a transmission pan mounted sideways.

A TCC solenoid converts electrical signals to mechanical ones that prompt the converter clutch to engage and disengage appropriately. “Get on the expressway, get up to 60, 70, 75… With no more lockup, the converter clutch is slipping its life away at high speed. Forgot the kinda Jeep, 80 SX4. Remove Clip Holding Solenoids – With the use of a pick or screw driver, remove the small c shaped clip holding the solenoid into place. Looks like a Volt, Sonata, and Taurus got it on. The torque converter clutch solenoid controls the pressure exerted by the transmission fluid on the torque converter clutch. … Unplug the wire from the solenoid by simply pulling it away from the solenoid. Dont go to a dealer, take it to a trans shop. I was wrong about the price of yours, my supplier LISTS them for $35 so you should find them for under $50. I will say I'm suprised at the size of the shavings on the … This signal causes the solenoid to move the valve that in turn moves the transmission fluid –which is pressurized- to the circuit of the clutch.

Those transmissions never overheated because they didn’t have the TCC feature. If there was a programming problem it would cause this problem from new. Dont chance that with a trans which has over 200k on it. Discard the solenoid. In a vehicle with an automatic transmission, the torque converter connects the power source from the load. Thanks again, JR. Re read what I said, in fact never mind, I’ll post it here again for you. God I miss that Jeep. I have sat in the driveway for a half an hour with a paperclip and small screwdrivers but I cannot seem to figure it out unless I want to cut the wire. This can cause various symptoms, such as slipping, overheating, and rough acceleration.

I'd avoid cutting into the harness if you can. The trans does not need to come out, but you do have to lower the trans enough for the side pan to clear the body, which needs to come off the trans so you can get at the valve body and whatnot. The equivalent location in a manual transmission would be the mechanical clutch. Most cars don’t have enough power to run in “lockup” without “unlocking” on a hill and “locking up” again when it levels out. Ensure the O-ring is properly lubricated. 3. - Torque converter clutch DTC present - TPS DTC present - Transfer case in low range (if equipped) - Transmission Relay DTC present - Transmission temperature too cold - Intermittent - Check transmission fluid-debris - Check transmission fluid-stall - 3-4 Shift Solenoid - Oil Pan contains excessive debris - Shaft or seal damage - TCC solenoid Now, for an interim fix, you could just snip the wire that feeds the TCC solenoid, tape it off, and be on your way, but I recommend you get that properly fixed ASAP.

I have been explaining this to you for some time now and I’m trying to put it as simple as I can since you are not a mechanic. Here are a couple of quotes from the links you provided " Highway vehicles generally use lower stall torque converters to limit heat production, and provide a more firm feeling to the vehicle’s characteristics" “In modern designs, the blade geometry minimizes oil velocity at low pump speeds, which allows the turbine to be stalled for long periods with little danger of overheating.”, Well I called a couple of transmission repair shops, and got quotes from $225 to $350 for them to do the work, including the cost of the part. My car has over 204.000 miles, so its not like it has long to live anyway. 3.tcc solenoid power circuit is open check the trans fuse. Any advice? Discard the solenoid. 1999.
