Governor Pressure Testing

GOVERNOR PRESSURE TESTING
1. Check A/T and engine fluid levels. If necessary, add fluid.
2. Warm up engine until engine oil and ATF reach operating temperature; after vehicle has been driven approx. 10 minutes.

ATF operating temperature: 50 - 80°C (122 - 176°F)





3. Install pressure gauge to governor pressure port.





4. Set parking brake and block rear wheels.
5. Jack up front wheels.
6. Set selector lever in D position and drive vehicle.
Be careful of rotating wheels.





Governor pressure:
- Governor pressure is not generated when vehicle is stopped. (front wheels are not rotating.)
- Governor pressure rises gradually in response to vehicle speed. (front wheel rotating speed.)

If not, check governor valve assembly. Refer to "DISASSEMBLY".
