What does a bad torque converter sound like?
The car will not move — as if the transmission is not hooked to the engine. Note that this noise occurs in all gears as well as park and neutral. It does disappear momentarily in between gears when shifting through neutral. This is different than what I’ve read about torque converter symptoms.
When does the transmission noise go away in a 4T60?
For example, a 4T60-E has a noise in neutral while stationary. The noise goes away when the transmission is in gear. Right away, you can rule out the torque converter. Since the pump is producing the same pressure in neutral as it is in gear, you can also rule it out.
Why does my transmission make so much noise?
Many types of noise are transmission related. Sometimes it’s nothing more than a normal noise that sounds louder because of bad mounts or because part of the transmission is touching the frame or underbody of the car.
Why does the converter noise go away when the transmission is in neutral?
Since the entire converter (pump, turbine and stator) turns while the transmission is in park and neutral, a converter noise will go away in those ranges. When the transmission is in gear and the drive wheels are stationary, the turbine in the torque converter doesn’t spin, because the turbine shaft is stationary.

Can a torque converter be a problem with a transmission?
It could be a problem with the transmission, or the transmission could be perfectly fine and it could be a problem with the torque converter. Torque converter issues on a lot of older transmissions can be diagnosed by carrying out a stall-speed test. Below we have outlined how you can safely and easily conduct a torque converter test.
When does a torque converter noise go away?
Torque converter noises are easy to isolate. Since the entire converter (pump, turbine and stator) turns while the transmission is in park and neutral, a converter noise will go away in those ranges.
