A/T FLUID CHECK
Fluid Leakage and Fluid Level Check
Check fluid leakage and check the fluid level. Refer to AT-17, "Checking A/T Fluid".
Fluid Condition Check
Check the A/T fluid condition.
STALL TEST
Stall Test Procedure
1. Check ATF and engine oil levels. If necessary, add ATF and engine oil.
2. Drive vehicle for approximately 10 minutes or until ATF and engine oil reach operating temperature.
3. Set parking brake and block wheels.
4. Install a tachometer where it can be seen by driver during test. •It is good practice to mark  the point of specified engine
rpm on indicator.
5. Start engine, apply foot brake, and place selector lever in “D” position.

TROUBLE DIAGNOSIS
Location of line pressure test ports are shown in the figure.
•Always replace pressure plugs  as they are self-sealing bolts.
Line Pressure Test Procedure
1. Check ATF and engine oil levels. If necessary, add ATF or
engine oil.
2. Drive vehicle for approx. 10 minutes or until engine oil and ATF reach operating temperature.
3. Install oil pressure gauge to corresponding line pressure test port.
4. Set parking brake and block wheels.
5. Start engine and measure line pressure at idle and stall speed. CAUTION:
• Keep the brake pedal pressed all the way down duringmeasurement.
• When measuring the line pressure at the stall speed, refer to "STALL TEST".
