Poor acceleration; flares when starting off in D, D3, S, 2, 1, and R; stall speed high in R

Probable cause(s)
  1. Shift cable broken or out of adjustment
  2. 5th clutch defective
  • Check for a loose shift cable at the shift lever and the transmission control lever.
  • Check the 5th clutch pressure.
  • Inspect the mainshaft and 5th clutch 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.
