• Check ATF level and check ATF cooler lines for
leakage and loose connections. If necessary, flush
ATF cooler lines.
• Check for a loose shift cable at the shift lever and the
transmission control shaft.
• 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.
• Measure line pressure.
• If the strainer is clogged, find the damaged
components that caused debris.
• Inspect the differential pinion gear for wear. If the
differential pinion gears are worn, replace the
differential assembly, replace the ATF strainer,
thoroughly clean the transmission, and flush the
torque converter, cooler, and lines.
• 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.

1st accumulator defective
2.
1st gears worn or damaged
3.
1st clutch defective
• Inspect 1st clutch pressure.
• Inspect the secondary shaft and 1st/2nd clutch
assembly for wear and damage.
• 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.
