Regulator valve stuck or spring worn

ATF strainer clogged

Mainshaft worn or damaged

Check the ATF level, and check the ATF cooler lines for leakage and loose connections. If necessary, clean the ATF cooler lines.

Notes

Check for a loose shift cable at the shift lever and the selector control lever.

Notes

Improper alignment of the ATF pump and the torque converter housing may cause ATF pump seizure. The symptoms are mostly an rpm-related ticking noise or a high pitched squeak.

Notes

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 cause ATF pump seizure.

Notes

Install the main seal flush with the torque converter housing when replacing the main seal. If you push it into the torque converter housing until it bottoms out, it will block the fluid return passage and result in damage.

Notes

Check the ATF strainer for debris. If the strainer is clogged, find the damaged components that caused the debris.

Notes

Inspect the differential pinion gears for wear. If the differential pinion gears are worn, replace the differential assembly, replace the ATF strainer, thoroughly clean the transmission, and clean the ATF cooler and the cooler lines.

Notes

Replace the torque converter.

Notes

Inspect the countershaft and the secondary shaft for wear and damage.
