Clutch Application Chart





a Low/Reverse clutch is holding until vehicle reaches 5 mph.

- D = Drive Clutch
- H = Hold Clutch
- O/R = Overrunning

Solenoid Operation Chart





a Solenoid will change state when vehicle speed is greater than 5 mph.

b TCC may be commanded ON early in 1st, 2nd and 3rd gears depending on transmission fluid temperature.

NH = Normally high

NL = Normally low

Pressure Chart - Diesel Engines

NOTE: Actual and commanded pressures will vary based on calibration and transmission adaptive strategies. All pressures listed are approximate.

Shift Speeds - Diesel Engines

NOTE: All shift speeds are nominal and will vary with calibration, model, axle ratio and tire size.

NOTE: Lower deceleration rates during coastdown due to higher braking efforts will force multi gear downshifts.





a The Torque Converter Clutch (TCC) locks in 3rd gear between the 2-3 and 3-4 shift.

Shift Speeds - Gas Engines

NOTE: All shift speeds are nominal and will vary with calibration, model, axle ratio and tire size.

NOTE: Lower deceleration rates during coastdown due to higher braking efforts will force multi gear downshifts.





a The Torque Converter Clutch (TCC) will lock: in 3rd gear between the 2-3 and 3-4 shift when the accelerator pedal is above 30%.

b The Torque Converter Clutch (TCC) will lock: in 3rd gear between the 2-3 and 3-4 shift with Tow/Haul ON.

c The Torque Converter Clutch (TCC) will lock: in 5th gear between the 4-5 and 5-6 shift when the accelerator pedal is below 30%.

Front Selective Shim Part Number Chart





a The target clearance with the correct front selective shim installed is between 0.15-0.45 mm (0.006-0.018 in).

Rear Selective Shim Part Number Chart





a The target clearance with the correct rear selective shim installed is between 0.8-1.1 mm (0.031-0.043 in).
