As torque converters wear, the vanes will bend. This can result in sluggish shifting or even failure to drive. When vanes just begin to bend, one of the earliest warning signs is the engine revving higher than normal.
The issue will disappear as the system begins to warm up. If the vehicle in question is having these troubles, then torque converter problems are a likely cause.
7 Sure Signs You're Having Transmission Problems
Here are some of the most common ones: Torque shudder — This is evidenced by the engine block shaking or quivering at the slightest acceleration, even on smooth surfaces. This is due to loss of torque from the stator not rotating properly.
A whirring sound at start-up — Torque converters contain numerous bearings, including a one-way clutch. This same noise can be caused by vacuum bubbles forming in the fluid as the pump starts to fail. Increased stall speed — As torque converter problems progress, it will take the transmission longer to engage the engine. This will lead to sporadic engagement and ultimately to complete failure.
What are some Symptoms of a Torque Converter starting to Fail?
This problem can be particularly severe in transmissions with lock-up converters. The death sound — A loud clacking or grinding noise is never good. The driver must stop the vehicle as soon as possible and call for help, otherwise the converter might circulate shards of metal throughout the entire transmission, forcing a complete replacement. Here are the steps involved: Contaminants in fluid — If you check the fluid and there are large amounts of black material, it either means your transmission or the torque converter clutches are damaged.
You should perform a fluid change first, run your car for a while, and check back again. Increased stall speed — A bad torque converter will take the transmission longer to engage the engine, resulting in higher than normal stall speeds.

Strange sounds — Any foreign sounds such as clicking or a revving noise could indicate a bad torque converter. How to Test for Torque Converter Problems This simple test can help to diagnose potential problems with the torque converter.
Afterwards, step on the gas lightly a few times, let it come back to idle, press down on the brakes, and then shift into drive. During this period, you are going to want to listen for any strange sounds such as clicking or revving or if you experience any lurching. If not, proceed to shift through all the gears including reverse and try to notice for any of the aforementioned signs again.

Finally, drive your car and test for the same things as well as shuddering or slipping. If they happen to become damaged, it will cause the transmission to make strange noises while driving. This is because there is metal to metal contact between the parts in the converter, which in turn creates metal chips that the transmission fluid picks up and cycles around the transmission.
Damaged torque converter seals — A damaged torque converter seal will allow fluid to leak out of the converter which will cause a number of problems, such as overheating, slippage, and shifting problems. The seal will need to be found and replaced.
Torque Converter Problems: Signs, Causes, & Replacement
Torque converter clutch failure will occur when it becomes jammed from locking up due to distortion, or if they burn from high heat temperatures. They can even break under severe conditions. If the clutches become stuck, your car will stay in gear even when you come to a complete stop.
Torque converter clutch solenoid — The torque converter clutch solenoid is an electronic component that controls the amount of fluid that is passed on to the torque converter clutch.
