Eliminating Torque Converter Shudder in Automatic Transmissions

Eliminating Torque Converter Shudder in Automatic Transmissions

It can be difficult to determine if shudder is a fluid-related issue or a costly mechanical problem.

As automatic transmissions age, the lockup torque converter’s ability to transfer torque smoothly can decline, and additive packages in automatic transmission fluids can deplete, resulting in torque converter clutch (TCC) shudder.

TCC shudder also can occur in brand-new automatic transmission fluids.

This is due to a frictional deficiency of the fluid and can be easily corrected with the use of a friction modifier such as Instant Shudder Fixx. It can be difficult to determine if shudder is a fluid-related issue or a costly mechanical problem. Instant Shudder Fixx is a low-cost diagnostic tool that can quickly and easily determine if shudder is a fluid-related problem or if the torque converter may be failing.
