Notes
• 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.
• Inspect the contact of the countershaft and secondary
shaft with the bearings. Check the ATF guide plates
for damage and wear. Inspect the 1st clutch feed pipe
for damage and out of round. If the 1st clutch feed
pipe is damaged or out of round, replace it. Replace
the secondary shaft if the bushing for the 1st clutch
feed pipe is damaged or out of round.
Replace the torque converter.
• Check for a misinstalled/damaged drive plate.
• Set idle rpm in gear to the specified idle speed. If still
no good, adjust the engine mounts.
• Check the stall speed.
• Check the D indicator, and check for loose connectors.
Inspect the transmission range switch. If the
transmission range switch is faulty, replace it. If the
transmission range switch is out of adjustment,
adjust it and the shift cable.
• Check for a loose shift cable at the shift lever and the
transmission control shaft.
• Check for a loose shift cable at the shift lever and the
transmission control shaft.
• Check the park pawl spring installation and the park
lever spring installation. If installation is incorrect,
install the spring correctly. Make sure that the park
lever stop is not installed upside down. Check the
distance between the park pawl shaft and the park
lever roller pin. If the distance is out of tolerance,
adjust the distance with the park lever stop.
Check the D indicator, and check for loose connectors.
Inspect the A/T clutch pressure control solenoid valve
body gasket for wear and damage. If the A/T clutch
pressure control solenoid valve is stuck, inspect the
CPC valves.
