Noise From Transmission In All Shift Lever Positions

Noise from transmission in all shift lever positions

ATF pump worn or binding

ATF strainer clogged

Mainshaft, countershaft, secondary shaft, and intermediary shaft bearings worn or damaged

Idler gears worn or damaged

Thrust washer seized, worn, or damaged

Notes

Check the line pressure A/T Pressure Test.

Notes

Improper alignment of the 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.

Notes

Check the ATF strainer for debris. If the strainer is clogged, find the damaged components that caused the debris. If no cause for contamination is found, replace the torque converter.

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 cooler and lines.

Notes

Replace the torque converter.

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, use the proper tools.

Notes

Install the main seal flush with the torque converter housing. 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

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

Notes

Inspect the park mechanism at the park lever link, park gear, and 2nd gears.

Notes

Inspect the mainshaft, the countershaft, the secondary shaft, the intermediary shaft, and idler gears for wear and damage.

Notes

Check the thrust washers on all shafts for seizure, wear, and damage.
