( 1 ) Station "D" is not used.Problem
The primary pressure is correct, but the maximum pressure is not correct.
Probable CauseInner spring (7) is weak or broken, and/or outer spring (8) is weak or broken.Problem
The pressure at one clutch is 0 kPa (0 psi).
Probable Cause
Selector piston plug (1) is not installed.
The selector piston (10) is stuck.
The modulation reduction valve (2) is stuck.Problem
The primary pressures at all the clutches are 0 kPa (0 psi).
Probable CauseThe probable cause is the pilot pressure. Perform the test in the Testing and Adjusting, "Pilot Pressure for Transmission Hydraulic Control Valve - Test and Adjust".Problem
The primary pressures at all the clutches are too low.
Probable CauseThe probable cause is the transmission oil pump. Perform the test in the Testing and Adjusting, "Pressure for Transmission Oil Pump - Test and Adjust".Problem
The primary pressure at one clutch is too low.
Probable Cause
Selector piston (10) is stuck.
Inner spring (7) is weak or broken, and/or outer spring (8) is weak or broken.
Incorrect inner spring (7) and/or outer spring (8) .
The primary pressure is set incorrectly. Add shims (5). Refer to Table 4.Problem
The primary pressure at one clutch is too high.
Probable Cause
Incorrect inner spring (7) and/or outer spring (8) .
The primary pressure is set incorrectly. Remove shims (5). Refer to Table 4.Problem
An additional clutch receives pressure oil in certain speeds.
Probable Cause
Decay orifice (4) is plugged.
The drain orifice in the return end of the rotary
