Line Pressure Test

Pressure Testing





- Location of pressure test port.

- Always replace pressure plugs as they are sell-sealing bolts.

LINE PRESSURE TEST PROCEDURE





1. Check A/T and engine fluid levels. If necessary, add fluid.
2. Warm up engine until engine oil and A.T.F. reach operating temperature after vehicle has been driven approx. 10 minutes. A.T.F.operating temperature: 50 - 80 (122 - 176 F)





3.Install pressure gauge to line pressure port.





4. Set parking brake and block wheels.

- Continue to depress brake pedal fully while line pressure test is being performed at stall speed.





5. Start engine and measure line pressure at idle and stall speed.

GOVERNOR PRESSURE TESTING





1. Check All and engine fluid levels. If necessary, add fluid.
2. Warm up engine until engine oil and A.T.F. reach operating temperature after vehicle has been driven approx. 10 minutes. A.T.F. 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" range 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 r.p.m.). If not, check governor valve assembly.
