what causes torque converter shudder
As mentioned, converter shudder is usually temperature related. As transmission fluid recycles back through the engine turbine, it picks up frictional heat. Once the amount of heat generated by this friction surpasses the transmissions cooler's ability to shed it, the fluid thins and power transfer becomes inconsistent.ransmissions can shudder in a very similar manner to torque converters. To determine whether the shudder is tranny or TC related, run your vehicle for a little while till it begin to shudder and immediately park it. With your foot on the brake, put the transmission in Drive, and apply light throttle.
The Torque Converter can go bad, and many people mistake an engine miss, torque converter shudder, or an engine vacuum leak for a converter going bad. An out of adjustment brake light switch can also cause the torque converter to no lock up sometimes.A sticking valve within the transmission is the usual cause of an erratic lock up that will mimic a bad converter. Rule out the obvious before you assume its going bad, and/or have it rebuilt.n out of adjustment brake light switch can also cause the torque converter to no lock up sometimes.
