15
Turn the ignition off.
Place the vehicle on a hoist that will allow all 4 wheels to rotate freely.
Connect a 700 kPa (100 PSI) transmission pressure gauge to the governor pressure
test port.
Start the engine.
Allow the transmission to reach normal operating temperature.
WARNING: Ensure all 4 wheels do not touch the ground.
Place the gear selector lever in Neutral with the wheels not turning and observe the
pressure gauge.
NOTE: The pressure gauge should read less than 20.6 kPa (3 PSI).
Bring the vehicle speed slowly to 40 km/h (25 MPH) and observe the pressure gauge
again.
NOTE: The pressure gauge should read 110-165 kPa (16-24 PSI).
Are both pressure gauge readings what they are supposed to be?
