- Warm the transmission oil to operating temperature.
- Run the engine at HIGH IDLE. Fully depress the brake pedal. Disengage the parking brake. Put the torque converter in a stalled condition with the transmission in third speed forward. Note the pressure on the gauge. The pressure should be 440 ± 70 kPa (64 ± 10 psi).
- This pressure pertains to a test that is done on the machine. The 440 ± 70 kPa (64 ± 10 psi) is not a bench test specification.
- If the pressure that is observed is not 440 ± 70 kPa (64 ± 10 psi), perform the following steps:
- Shut off the engine.
- Remove the torque converter outlet relief valve. Refer to Power Train Disassembly and Assembly, "Torque Converter Outlet Relief Valve - Remove" for your machine.
