valve is stuck, inspect the
CPC valves.

Check for a clogged orifice in
the transmission fluid pressure
switch connector. If the
orifice is clogged, remove it
and clean the connector.

Check the 3rd and 4th clutch
pressures.

Inspect the clutch piston,
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 plates for wear and
damage, and inspect the
clutch wave-plate height. If
the discs and flat-plates are
worn or damaged, replace the
discs and flat-plates as a set. If
the wave-plate height is out of
tolerance, replace the wave-
plate. If the discs and plates
are OK, adjust the clearance
with the clutch end-plate.

Excessive shock or flares on 4-5
upshift or 5-4 downshift

defective

2. A/T clutch pressure control

solenoid valve B defective

3. A/T clutch pressure control

solenoid valve C defective

4. CPC valve B defective

5. CPC valve C defective

6. Foreign material in

7. Shift valve C defective

8. Shift valve E defective

9. Kick-down valve or kick-

down short valve defective

10. 4th accumulator defective

Check for a stored DTC, and
check for loose connectors.

Inspect the O-rings, and check
the shift solenoid valve for
seizure.

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

Check the 4th and 5th clutch
pressures.

Inspect the clutch piston,

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 plates for wear and
damage, and inspect the
clutch wave-plate height. If
the discs and flat-plates are
worn or damaged, replace the
discs and flat-plates as a set. If
the wave-plate height is out of
tolerance, replace the wave-
plate. If the discs and plates
are OK, adjust the clearance
with the clutch end-plate.

Noise from transmission in all
shift lever positions

1. ATF pump worn or binding

2. Idler gears worn or

damaged

3. Thrust washer seized up,

worn, or damaged

Improper alignment of ATF pump
and the torque converter housing
may cause the ATF pump seizure.
The symptoms are mostly an rpm-
related ticking noise or a high
pitched squeak.

Vehicle does not accelerate
above 31 mph (50 km/h)

Torque converter one-way clutch
defective

Replace the torque converter.

Vibration in all shift lever
positions

Drive plate defective or
transmission misassembled

Check for a
misinstalled/damaged drive
plate.

Adjust the engine and
transmission mounts.

Check the stall speed.

Shift lever does not operate
smoothly

1. Transmission range switch

defective or out of
adjustment

2. Shift cable broken or out of

adjustment

3. Connection between shift

cable and transmission or
body is worn

Check for a stored DTC, 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 lever.

Transmission does not shift into
P

1. Shift cable broken or out of

adjustment

Check for a loose shift cable
at the shift lever and the
