Notes
• Check the D4 indicator, and check for loose connectors.
Inspect the O-ring, and check the shift solenoid valve
for seizure.
• Inspect the A/T clutch pressure control solenoid valve
body gasket and ATF feed pipes for wear and damage.
If the A/T clutch pressure control solenoid valve is stuck,
inspect the CPC valves.
• Check for a loose shift cable at the shift lever and the
transmission control shaft.
• Check the ATF strainer for debris. If the ATF strainer is
clogged with particles of steel or aluminum, inspect the
ATF pump. If the ATF pump is OK, find the damaged
components that caused the debris. If no cause for the
contamination is found, replace the torque converter.
• Check the 1st clutch pressure.
• 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. If the discs and plates
are worn or damaged, replace them as a set. If they are
OK, adjust the clutch end plate clearance.
Check the D4 indicator, and check for loose connectors.
•
Inspect the O-ring, and check the shift solenoid valve

• Inspect the A/T clutch pressure control solenoid valve
body gasket and ATF feed pipes for wear and damage.
If the A/T clutch pressure control solenoid valve is stuck,

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.
