The brakes will not engage.
Both brakes will not release.Transmission
No. 1. ProblemThe transmission does not operate in any speed. The transmission does not engage in all speeds or there is clutch slippage.Probable Cause
Low oil pressure in the system. Low oil pressure can be caused by one of the following problems.
Low oil level
The control linkage is loose or the adjustment is not correct.
Failure of the transmission oil pump or the pump drive
Air leakage on the inlet side of the transmission oil pump
Incorrect priority valve adjustment
Oil leakage inside the transmission
Incorrect adjustment of the modulation relief valve or the valve does not close.
The load piston or the differential valve operation is incorrect.
Mechanical failure in the transmission
Failure of the torque converter
Failure of the transfer and bevel gears
Incorrect steering clutch operation
Failure in the final drivesNo. 2. ProblemThe transmission does not shift.Probable Cause
The control linkage is loose or the adjustment is not correct.
Low oil level
Low clutch pressuresNo. 3. ProblemSlow shifts.Probable Cause
Low oil pressure
The adjustment of the control linkage is not correct.
Air leakage on the inlet side of the transmission oil pump.
The load piston or the differential valve does not move.No. 4. ProblemThe transmission engages very suddenly. This sudden engagement causes rough shifting.Probable Cause
The initial setting of the modulation relief valve is not correct.
The load piston or the differential valve does not move.
Valve springs that are weak or damagedNo. 5. ProblemThe transmission operates in FORWARD speeds only.Probable Cause
The control linkage is loose or the adjustment is not correct.
