2. A/T clutch pressure control
solenoid valve A defective
3. A/T clutch pressure control
solenoid valve B defective
4. A/T clutch pressure control
solenoid valve C defective
5. Shift cable broken or out of
adjustment
6. Connection between shift cable
and transmission or body w o r n
7. Input shaft (mainshaft) speed
sensor defective
8. Output shaft (countershaft)
speed sensor defective
9. ATF temperature sensor
defective
10. CPC valve A defective
11. CPC valve B defective
12. CPC valve C stuck
13. Foreign material in separator
plate orifice
14. Shift valve C defective
15. Shift valve E defective
16. Servo control valve defective
17. 1st accumulator defective
18. 1st check ball stuck
19. One-way check ball stuck
20. 1st clutch defective
Check for a stored DTC, and check for loose
connectors.
Check the shift solenoid valve for seizure, and
inspect the O-rings.
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 lever.
Check the 1st clutch pressure.
Inspect the clutch piston, clutch piston check valve,
and O-rings. Check the spring retainer for w e a r 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 w e a r and
damage, and inspect the clutch waved-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 plate.
