Automatic transmission torque converter slip is the difference in rotation speeds of the drive and driven shafts of the torque converter that occurs when transmitting torque from the engine to the gearbox.
Causes of torque converter slippage:
* Friction lining wear: Over time, the friction linings on the torque converter output shaft can wear out, resulting in reduced traction and increased slip.
* Contaminated transmission fluid: Dirty transmission fluid can contain particles that can get trapped between the friction linings, reducing their grip and increasing slippage.
*Low Transmission Fluid Pressure: Low transmission fluid pressure can cause the friction linings to not engage sufficiently, which also increases slippage.
* Torque Converter Leaks: Transmission fluid leaks from the torque converter can result in loss of pressure and increased slippage.
Symptoms of torque converter slippage:
* Increased Shift Time: A slipping torque converter can slow down shift times as the transmission tries to compensate for the loss of power.
*Power Loss During Acceleration: When the torque converter slips, the engine may rev at higher speeds without providing adequate acceleration.
* Noise or vibration when shifting gears: Torque converter slippage may cause noise or vibration as transmission fluid circulates at a higher speed.
* Increased fuel consumption: A slipping torque converter can reduce transmission efficiency, resulting in increased fuel consumption.
