Noise From Transmission In All Shift Lever Positions

Noise from transmission in all shift lever positions

ATF pump worn or binding

Mainshaft bearing, countershaft bearing, or secondary shaft bearing defective

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 result in ATF pump seizure if not detected. 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 ATF strainer for clogging with particles of steel or aluminum. If the ATF strainer is clogged, replace it, and clean the torque converter, the ATF warmer, and the ATF warmer lines.

Notes

Inspect the mainshaft, the countershaft, and the secondary shaft for wear or damage.
