Notes
• Check for a stored DTC, and check for loose
connectors.
• Inspect the solenoid valve filter/gasket and the
O-rings for wear and damage, and inspect the
solenoid valves for seizure.
• Check the input shaft (mainshaft) speed sensor
and the output shaft (countershaft) speed sensor
installation.
• Check for a loose shift cable at the shift lever and
the transmission control shaft.
• Check the 1st clutch pressure.
• Inspect the clutch piston, the clutch piston check
valve, and the O-rings. Check the spring retainer
and the retainer seal for wear and damage.
Inspect the clearance between the clutch end-
plate and the top disc. If the clearance is out of
tolerance, inspect the clutch discs and the plates
for wear and damage. If the discs are worn or
damaged, replace them as a set. Inspect the
clutch wave-plate height. If the height is out of
tolerance, replace the wave-plate. If the discs and
the plates are OK, adjust the clearance with the
clutch end-plate.
• Inspect the 1st clutch feed pipe. If the 1st clutch
feed pipe is scored, replace the end cover.
• Replace the secondary shaft if the bushing for the
1st clutch feed pipe is loose or damaged.
• Check for a stored DTC, and check for loose
connectors.
• Inspect the solenoid valve filter/gasket and the
O-rings for wear and damage, and inspect the
solenoid valves for seizure.
• Check the input shaft (mainshaft) speed sensor
and the output shaft (countershaft) speed sensor
installation.
• Check for a loose shift cable at the shift lever and
the transmission control shaft.
• Inspect the clutch piston, the clutch piston check
valve, and the O-rings. Check the spring retainer
for wear and damage. Inspect the clearance
between the clutch end-plate and the top disc. If
the clearance is out of tolerance, inspect the
clutch discs and the plates for wear and damage.
If the discs are worn or damaged, replace them
as a set. Inspect the clutch wave-plate height. If
the height is out of tolerance, replace the wave-
plate. If the discs and the plates are OK, adjust
the clearance with the clutch end-plate.
Check for a missing shift fork bolt on the shift
•
fork shaft.
• Check the 4th clutch pressure.
• Inspect the servo valve and the O-ring.
