Delayed engagement after shifting from N to D or S, or excessive shock when shifting
Probable cause(s)
Shift solenoid valve C defective
A/T clutch pressure control solenoid valve D defective
Shift cable broken or out of adjustment
Connection between shift cable and transmission or shift lever is worn
ATF temperature sensor defective
Low ATF level
Foreign material in separator plate orifice
1st accumulator defective
ATF strainer clogged
Lock-up shift valve defective
1st clutch defective
Clearance between clutch end-plate and top disc incorrect
Notes
Inspect the shift solenoid valve C function with the HDS.
Check for a seized shift solenoid valve, and inspect the O-rings.
Inspect A/T clutch pressure control solenoid valve D with the HDS.
Check for a loose shift cable at the shift lever and the selector control lever.
Inspect the ATF temperature sensor O-ring for wear and damage.
Check the ATF level. If the level is below the lower level, check the ATF cooler lines for leaks and loose connections. If necessary, clean the ATF cooler lines.
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, find the damaged components that caused the debris. If no cause for contamination is found, replace the torque converter.
Check the lock-up shift valve in the main valve body for free movement, and check the valve spring for wear and damage.
Check the 1st accumulator piston, the O-ring, and the spring in the manual valve body for wear and damage.
