Notes
•
Check the ATF level and check the ATF cooler lines for
leakage and loose connections. If necessary, flush the
ATF cooler lines.
•
Check for a loose shift cable at the shift lever and the
transmission control shaft.
•
Check the line pressure.
•
Improper alignment of ATF pump and torque converter
housing may cause ATF pump seizure. The symptom is
mostly an rpm-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.
•
Check the 2nd clutch pressure.
•
Inspect the clutch piston and O-rings. Check the spring
retainer for wear and damage. Inspect the clutch end-
plate-to-top-disc clearance. If the clearance is out of
tolerance, inspect the clutch discs and plates for wear
and damage. If the discs and plates are worn or
damaged, replace them as a set. If they are OK, adjust
the clutch end plate clearance.
