Noise From Transmission In All Shift Lever Positions

Noise from transmission in all shift lever positions

Diagnostic Procedure:

1. ATF pump worn or binding

2. ATF strainer clogged

3. Idler gears worn or damaged

4. Bearings on mainshaft, countershaft, secondary shaft, and intermediary shaft worn or damaged

5. Thrust washer seized up, worn, or damaged

Also check for:

- Improper alignment of ATF pump and torque converter housing may cause ATF pump seizure. The symptoms are mostly an rpm-related ticking noise or a high pitched squeak.
- Check the ATF strainer for debris. If the strainer is clogged, find the damaged components that caused the debris.
- Be careful not to damage the torque converter housing when replacing the main ball bearing. You may also damage the ATF pump when you torque down the main valve body. This will result in ATF pump seizure if not detected. Use the proper tools.
