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

Late shift after
shifting from N
to R, or excessive
shock when
shifted into R

1. Shift solenoid

valve D defective

2. A/T clutch

pressure control
solenoid valve A
defective

3. Shift cable broken

or out of
adjustment

4. Connection

between shift
cable and
transmission or
body is worn

5. Input shaft

(mainshaft) speed
sensor defective

6. Output shaft

(countershaft)
speed sensor
defective

7. ATF temperature

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

Test the solenoid valve function
with the HDS.

Inspect the A/T clutch pressure
control solenoid valve body
gasket, the ATF feed pipes, and
the O-rings, for wear and
damage.

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

Check for a loose shift cable at
the shift lever and the
transmission control lever.

Check the input shaft
(mainshaft) speed sensor and the
output shaft (countershaft) speed
sensor installation.

Inspect the sensor O-ring for
wear and damage.

Check for a missing shift fork

10. Shift valve E

defective

11. 5th/reverse

accumulator
defective

12. Lock-up shift

valve defective

13. 5th clutch

bolt on the shift fork shaft.

Inspect the servo valve O-ring.

Check the shift fork shaft detent
for wear and damage.

Check for a clogged orifice in
the separator plate. If the orifice
is clogged, remove it and clean
the separator plate orifice.

Check the ATF strainer for
debris. If the strainer is clogged
with panicles 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 contamination is
found, replace the torque
converter.

Check shift valve D in the main
valve body.

Inspect the 5th accumulator
piston, the O-ring, and the
spring for wear and damage in
the servo body.

Check the lock-up shift valve in
the regulator valve body.

Check the 5th clutch pressure.

Inspect the mainshaft and the
5th clutch for wear and damage.

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

Late shift after
shifting from D3
to 2, or 2 to 1

1. A/T clutch

pressure control
solenoid valve A
defective

2. A/T clutch

pressure control
solenoid valve B
defective

3. A/T clutch

pressure control
solenoid valve C
defective

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

Test the solenoid valve function
with the HDS.

Inspect the A/T clutch pressure
control solenoid valve body
gasket, the ATF feed pipes, and
the O-rings for wear and
damage.

1. Input shaft

(mainshaft) speed
sensor defective

2. Output shaft

(countershaft)
speed sensor

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

Check the input shaft
(mainshaft) speed sensor and the
output shaft (countershaft) speed
sensor installation.

Inspect the sensor O-ring for
wear and damage.

Inspect the A/T clutch pressure
control solenoid valve body
gasket, the ATF feed pipes, and
the O-rings for wear and
damage.

Check the input shaft
(mainshaft) speed sensor and the
output shaft (countershaft) speed
sensor installation.

Inspect the sensor O-ring for
wear and damage.

Check for a clogged orifice in
the separator plate. If the orifice
is clogged, remove it and clean
the separator plate orifice.

Check the ATF strainer for
debris. If the 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 contamination is
found, replace the torque
converter.
