The Transmission Clutch Does Not Engage
Follow this procedure if the machine does not operate in specific gears.
Check the system pressure.
Reference(PL72 LRC and HRC) Specifications, Systems Operation and Testing and Adjusting, UENR4132, "Relief Valve (Transmission) - Test and Adjust" .Reference(PL83 LRC and HRC) Specifications, Systems Operation and Testing and Adjusting, UENR4141, "Relief Valve (Transmission) - Test and Adjust" .Reference(PL87 LRC and HRC) Specifications, Systems Operation and Testing and Adjusting, UENR4141, "Relief Valve (Transmission) - Test and Adjust" .Expected Results
The system pressure is correct.Results
OK: If the original problem has not been is not resolved, proceed to Step 3.
NOT OK: The cause of the problem may be the adjustment of the main relief valve. The main relief valve maintains the system pressure in the control section of the power train oil pump. Proceed to Step 2.
Adjust the pressure setting of the main relief valve.

The pressure setting of the main relief valve is correct.Results
OK: The pressure setting of the main relief valve is correct. If the original problem has not been resolved proceed to Step 3.
NOT OK: Proceed to Step 4.
Check the pressure at the clutch.

Personal injury can result if the machine moves while testing.If the machine begins to move during test, reduce the engine speed immediately and engage the parking brake.
Start the engine. Operate the engine at low idle.
Press down the service brake pedal in order to engage the brakes.
Disengage the parking brake.
Shift the transmission into a gear that requires the use of the clutch that is not functioning correctly.
Measure the pressure at the clutch that does not engage.Expected Results
The hydraulic pressure is equal to main relief on clutches 1 through 4, or 2241 kPa (325 psi) on clutch 5 when the clutch is engaged.Results
OK: Proceed to Step 8.
NOT OK: Proceed to Step 5.
Follow the procedure in this reference.Refer to "System Pressure Is Low" in this module under Troubleshooting, "Power Train Oil".Results
REPAIRED, OK: The original problem is resolved. Stop.
NOT OK: The system pressure is correct but the problem is not resolved. Proceed to Step 5.
Interchange modulating valves.
Interchange one of the modulating valves that should be engaged with one modulating valve that should not be engaged.
Determine whether the problem follows one particular valve.
Repeat the procedure for all modulating valves that affect the gear that is not functioning properly.Results
FOLLOWS: The problem follows one valve. Proceed to Step 6.
DOES NOT FOLLOW: Proceed to Step 7.
Replace the transmission
