Late shift after shifting to R position/mode from N position/mode, and return to N position/mode
Probable cause(s)
Low transmission fluid (HCF-2) level
Reverse brake defective
Reverse brake piston stuck
Shift cable broken or out of adjustment
Manual valve lever and lever pin worn or damaged
Transmission fluid strainer or transmission fluid filter clogged
Valve body assembly defective
Transmission fluid feed pipe worn, damaged, or out of round
Transmission range switch defective or out of adjustment
Stator shaft worn or damaged
Torque converter turbine speed sensor defective
PCM defective
Notes
Inspect the reverse brake piston and the O-rings. Check the spring retainer for wear and damage. Inspect the clearance between the brake end-plate and the top disc. If the clearance is out of tolerance, inspect the brake 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 clearance with the brake end-plate.
Check for a loose shift cable at the shift lever and the transmission control lever.
Check the manual valve lever and lever pin for wear and damage.
Check the transmission fluid strainer and the transmission fluid filter for debris. If the transmission fluid strainer or the transmission fluid filter is clogged, find the damaged components that caused debris.
Check the valve body assembly for wear and damage.
Check the transmission fluid feed pipe for wear, damage, and out of round.
Check the stator shaft for wear and damage.
Check the torque converter turbine speed sensor for wear and damage, and also check the O-ring for wear and damage.
