Where is the torque converter lock up solenoid?
Torque converter lock-up is engaged through a solenoid mounted inside the transmission. When the solenoid is energized it redirects the fluid flow back through the input shaft to put pressure against the clutch assembly allowing it to engage with the front of the torque converter.
How do I know if my torque converter is locked up?
Put the pedal to the metal While pressing on the brake pedal, press the accelerator to the floor for two to three seconds. Don’t exceed five seconds, or you risk blowing out the transmission. The RPM the engine maxes out at is the stall speed.
How do you unlock a torque converter?
Unlocking the torque converter is achieved by disconnection of the +12 volts, or the transmission downshifts out of 4th gear. We also include a cruise control style brake switch that works perfectly to disconnect the +12 volt power to the lock up module when the brakes are applied.
What would cause a torque converter to lock up?
However, when the engine turns more slowly it causes the torque converter to slip, creating heat. Slipping reduces fuel economy and heat can damage the converter and the transmission. The solution is to lock the converter. Lock-up eliminates the slippage, which reduces heat and improves fuel economy.
What cause a torque converter to stay locked up?
A cold engine temperature: There are cases where the converter may not lockup except the coolant temperature reaches 120°F. Lockout of the overdrive unit: An overdrive unit that is locked-up causes the torque converter lockup to also be locked out.
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 torque converter clutch located in a car?
Transmission Torque Converter Clutch (TCC) Solenoid: DESCRIPTION Positioned between the rear of the engine and the front of the transmission is the torque converter. The torque converter is responsible for transmitting the engine’s torque and power to the transmission.
Where is the lockup clutch in a transmission converter?
To prevent slipping at certain speeds (normally speeds exceeding 37 mph) a lockup clutch located inside the converter locks the engine’s output drive to the transmission’s input shaft to achieve a 1:1 ratio – meaning 100% of the engine’s power is now reaching the transmission.
What happens when the torque converter does not disengage?
If you think of it in a non-technical way, the torque converter clutch does the same thing inside an automatic transmission that your standard clutch does on a manual transmission. If the TCC fails to disengage when the vehicle comes to a stop, the engine will stall .
