TRANSMISSION TESTS, INSPECTIONS, AND ADJUSTMENTS - CONTINUED
SOLENOID VALVE (TRANSMISSION CLUTCH) TESTING
CAU T I ON
Care must be taken to ensure that fluids are contained during inspection and testing of machine. Be
prepared to collect fluid with containers before opening any compartment or disassembling any com-
ponent containing fluids.
Dispose of fluids according to local regulations and mandates.
Solenoid Valves Test
N OT E
· This test will determine whether solenoid coil is energized and solenoid plunger is shifting to permit flow of oil
through modulating valve.
· Solenoids are located on modulating valve that is controlled by solenoid. Direction clutch pressure taps and
speed clutch pressure taps are installed on modulating valves. Modulating valves are located on top of trans-
mission, beneath cab.
· Transmission is equipped with these modulating valves:
Modulating valve for clutch 1 (1) (forward low)
Modulating valve for clutch 2 (2) (forward high)
Modulating valve for clutch 3 (3) (reverse)
Modulating valve for clutch 4 (4) (second speed)
Modulating valve for clutch 5 (5) (third speed and fourth speed)
Modulating valve for clutch 6 (6) (first speed)
· All tests and adjustments must be made while transmission oil is at normal operating temperature.
