Notes
  • Check the ATF level, and drain the ATF if it is over-filled.
  • Check the 1st, 2nd, 3rd, 4th, and 5th clutch pressures.
  • Check for 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 with particles of steel or aluminum, inspect the ATF pump. If the ATF pump is OK, find the damaged components that caused the debris. If no cause for contamination is found, replace the torque converter.
  • Check the relief valve in the main valve body for free movement, and check the valve spring for wear and damage.
  • Inspect the mainshaft, secondary shaft, 1st, 2nd, 3rd, 4th, and 5th clutches 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 clearance between the clutch end-plate and the top disc. If the clearance is out of tolerance, inspect the clutch discs and plates for wear and damage, and inspect the clutch wave-plate height. If the discs and plates are worn or damaged, replace them as a set. If the wave-plate height is out of tolerance, replace the wave-plate. If they are OK, adjust the clearance with the clutch end-plate.
  • Inspect the 2nd, 3rd, and 4th clutch feed pipes.
  • If the 2nd clutch feed pipe is scored, replace the end cover.
  • If the 3rd or 4th clutch feed pipe is scored, replace it and the O-rings under the feed pipe flange.
  • Replace the secondary shaft if the bushing for the 2nd clutch feed pipe or 4th clutch feed pipe is loose or damaged.
  • Replace the mainshaft if the bushing for the 3rd clutch feed pipe is loose or damaged.
