This test is performed to insure proper control pressure is provided to the clutches in the transmission.Test Preparation
Refer to the section titled Machine Preparation for Testing and Adjusting in this manual.
The operator should lower the grapple and the decking blade to the ground.
Put blocks in front of the wheels and behind the wheels.
Install the steering frame lock.
Perform the following procedure to warm the transmission oil:
Engage the parking brake.
Lower the implement.
Push the transmission speed upshift control switch into the fifth gear position.
Place the transmission direction control switch in the FORWARD position.
Operate the engine at high idle. Monitor the gauge for the torque converter oil temperature that is on the dash panel. Reduce the engine speed and shift the transmission into the NEUTRAL position when the gauge enters the high temperature area. Shift the transmission back into gear once the temperature returns to normal.
Allow only authorized personnel on the machine. Keep unauthorized personnel off the machine and in clear sight of the operator.Note: All tests and all adjustments must be made while the transmission oil is at normal operating temperature.Test for Clutch Valve Pressure

(9) Torque convertor lubrication oil pressure tap
Attach tooling (A) or tooling (B) to each of the taps (1) through (6).Note: The cab may need to be tilted to gain access to the pressure taps.
Engage the parking brake. Shift the transmission direction control switch to the NEUTRAL position. Start the engine and operate the engine at low idle.
Depress the service brake pedal and hold the service brake pedal. Release the parking brake. Make sure that the machine is in first speed. Watch the pressure gauges. Shift the transmission switch from the NEUTRAL position to the FORWARD position. Increase the engine speed to high idle. Make sure that the transmission oil is at normal operating temperature. The needle on the pressure gauge for the Number 1 clutch should rise. The needle on the pressure gauge for the Number 6 clutch should rise. The pressure readings must be within the values in Table 1.With the transmission in the
