Vehicle moves in , , , , but not in position |

1. Shift cable broken or out of adjustment
2. 2nd accumulator defective
3. 2nd gears worn or damaged
4. 2nd clutch defective

- Check for a loose shift cable on the shift lever and transmission control shaft.
- Check the indicator light indication and check for loose connectors. Inspect the O-rings and check the shift solenoid valve for seizure.
- Inspect the mainshaft and 2nd clutch assembly for wear and damage.
- Inspect the clutch piston, clutch piston check valve and O-rings. Check the spring retainer for wear 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 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 clutch end plate.

Vehicle moves in , , , , but not in position |

1. Shift fork shaft stuck
2. Shift cable broken or out of adjustment
3. 4th clutch defective
4. Reverse gears worn or damaged

- Measure line pressure and 4th clutch pressure.
- Check for a missing shift fork bolt on the shift fork shaft.
- Check for a loose shift cable on the shift lever and transmission control shaft.
- If the ATF strainer is clogged with particles of steel or aluminium, inspect the ATF pump. If the ATF pump is OK and no cause for the contamination is found, replace the torque converter.
- Inspect the reverse selector gear teeth chamfers and inspect engagement teeth chamfers of the countershaft 4th gear and reverse gear. Replace the reverse gears and the reverse selector if they are worn or damaged. If the transmission makes clicking, grinding, or whirring noises, also replace the mainshaft 4th gear, reverse idler gear and countershaft 4th gear.
- If the 4th clutch feed pipe guide in the end cover is scored by the mainshaft, inspect the ball bearing for excessive movement in the transmission housing. If the ball bearing is OK, replace the end cover as it is dented. The O-ring under the guide is probably worn.
- Replace the mainshaft if the bushing for the 1st and 4th clutch feed pipes are loose or damaged. If the 4th clutch feed pipe is damaged or out of round, replace the end cover.
- Inspect the clutch piston, clutch piston check valve and O-rings. Check the spring retainer for wear 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 wear and damage. If the discs and plates are worn and damaged, replace them as a set. If they are OK, adjust the clearance with the clutch end plate.
