Noise from
transmission in all
shift lever
positions 1.
2.
ATF pump worn or binding
Mainshaft bearing, countershaft
bearing, or secondary shaft
bearing defective 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.
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.
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.
Inspect the ATF strainer is clogged with particles
of steel or aluminum. If the ATF strainer is
clogged, replace it, and clean the torque
converter, cooler, and lines.
Inspect the mainshaft, the countershaft, and the
secondary shaft for wear or damage.
