• Check for a stored DTC, and check for loose
connectors.
• Check the shift solenoid valve for seizure, and
inspect the O-rings.
• Check the 4th and 5th clutch pressures.
• Inspect the clutch piston, clutch piston check
valve, 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, and inspect the clutch w a v e d -
plate height. If the discs and flat-plates are w o r n
or d a m a g e d , replace the discs and flat-plates as a
set. If the waved-plate height is out of tolerance,
replace the waved-plate. If the discs and plates
are OK, adjust the clearance w i t h the clutch end
