There could be a lot of things that could cause problems in the torque converter. Below are some of the most common: 1 Matching the torque converter with a non-stick engine it wasn’t designed for can cause it to fail really quickly. 2 Towing cargo that exceeds the vehicles towing capacity of a long period of time can damage the torque converter. 3 Old and worn out internal vehicular components will also lead to failures in the torque converter.
Why does my torque converter bend?
Wear and tear in torque converters will cause the vanes to bend, resulting in slow shifting or failure to drive. A symptom of bent vanes is that the engine will rev higher than usual, with the sound turning normal as the system warms up. Torque converter issues are a possible cause of such issues in the vehicle.
Why does my transmission shudder?
The cause of this issue is a torque converter failing to effectively distribute power for the transmission.
What does it mean when your RPM is lower than your engine?
An RPM reading lower than your engine and torque converters specifications means that the torque converter need a repair or replacement. An unusually high RPM reading indicates a slip in the transmission, which will have to be investigated.
What does it mean when a torque converter makes a loud noise?
Loud grinding or clacking sounds – These are never a good sign. When being caused by the torque converter, it indicates that its internal mechanism is disintegrating. Stop driving immediately and call in a technician to assess the damage. If you keep on driving, you risk the converter circulating metal shards through the transmission, and you’ll end up having the whole thing replaced.
