Notes 

• Inspect the transmission range switch .
• Check for a loose shift cable at the shift lever and the control lever .
• Adjust the engine output.
• Inspect the clearance between the forward clutch end-plate and the top disc . If the clearance is out of tolerance, replace the input shaft assembly.
• Inspect the reverse brake piston and the O-rings. Check the spring retainer/return spring assembly for wear and damage. Inspect the clearance between the reverse brake end-plate and the top disc . If the clearance is out of tolerance, inspect the reverse brake discs and reverse brake 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 reverse brake end-plate.
• Check the sun gear for wear and damage. If the sun gear is worn or damaged, replace it and also check the planetary carrier pinion gears, the forward clutch, and the drive pulley shaft splines for wear and damage.
• Check the manual valve for wear and damage.
• Check the valve body assembly for wear and damage.
• Check the stator shaft for wear and damage.
