Can a torque converter clutch be unplugged?
Unplugging the torque converter clutch will not harm the transmission or cause it to overheat. This is just a regular three speed automatic transmission with the TCC lock up feature. When the TCC solenoid is unplugged it reverts the transmission back into a regular automatic three speed.
What happens when your VCT solenoid goes bad?
If your VCT solenoid is going bad or has gone bad on you, it’ll usually result in your car’s check engine light coming on. This is one of the reasons why you shouldn’t ever ignore the check engine light, as it could indicate a serious issue with a part as important as your VCT solenoid.
Where is the lock up solenoid on a TCC?
The Lockup solenoid is under the side cover. Sometimes the engine cradle needs to be lowered to get the side pan off. The solenoid is around $50. Dont go to a dealer, take it to a trans shop. $600 is WAY too much to pay for this.
How does a VCT solenoid work on a camshaft?
They work by accepting a signal from the powertrain control module and helping to regulate the flow of oil moving in the direction of the cavity in the camshaft phaser. This flow would be disrupted without fully-functioning VCT solenoids in place.
What happens when the torque converter is locked up?
Another symptom of torque converter lockup is that the transmission will shift into gears at random. Also, it will not allow the overdrive gear to engage immediately upon demand. Your car will act like it is bogging down, until the torque converter engages the overdrive.
What to do if you have problems with your VCT solenoid?
At the first sign of trouble with a VCT solenoid, you should drive right down to your certified mechanic and have them take a closer look at it. They can tell you if your VCT solenoid is the part that’s giving your cars problems and replace it, if necessary.
What is the purpose of the torque converter clutch?
The purpose of the Transmission Converter Clutch (TCC) feature is to eliminate the power loss of the torque converter stage when the vehicle is in a cruise mode. The TCC System uses a solenoid-operated valve to couple the engine flywheel to the output shaft of the transmission through the torque converter.
What causes a car to stall when the torque converter fails?
Vincent Ciulla is a certified master automotive technician who has diagnosed and repaired light trucks, domestic and foreign cars, and diesel engines, for more than three decades. A common problem on many General Motors cars is the Torque Converter Clutch fails to release and causes the car to stall when it comes to a stop.
Unplugging the torque converter clutch will not harm the transmission or cause it to overheat. This is just a regular three speed automatic transmission with the TCC lock up feature. When the TCC solenoid is unplugged it reverts the transmission back into a regular automatic three speed.
What causes a GM torque converter to lock up?
Most of the time it is a stuck Torque Converter Clutch (TCC) solenoid, but this is not the only cause of this problem. General Motors has issued a few Technical Service Bulletins (TSBs) relating to this problem. There is also a specific diagnostic procedure to determine the exact cause of the TCC problem.
Where is the solenoid valve on a torque converter?
Today we’ll be dealing with a Torque Converter Clutch Solenoid Valve. You will see how to locate, remove and test this solenoid valve. The torque converter on an automatic transmission transmits engine torque and power to the transmission. To prevent slippage a lockup clutch is located inside the converter.
What are the conditions for the converter clutch to apply?
For the converter clutch to apply, two conditions must be met: Internal transmission fluid pressure must be correct. The ECM must complete a ground circuit to energize the TCC solenoid that moves a check ball in the fluid line. This allows the converter clutch to apply when hydraulic pressure is correct.
