Hydraulic Pressure Tests
CAUTION:
DO NOT allow engine to run at maximum stall speed for more than 5 seconds. Run engine with transaxle in Neutral for one minute to cool transaxle after each test is completed.
- Block wheels. Connect tachometer to engine. Connect appropriate pressure gauge to hydraulic pressure port (square head plug, marked "L"). See Fig 1.
- Run engine until normal operating temperature is obtained. Ensure engine is idling within specification. Refer to underhood emissions label. Shift transaxle into gear as applicable and record hydraulic pressure. Firmly apply brake pedal. Steadily increase engine RPM to WOT and record hydraulic pressure. Release accelerator. DO NOT allow engine to operate at full stall speed for more than 5 seconds.
- Before shifting into each gearshift lever position, run engine with transaxle in Neutral for one minute to cool transaxle. Repeat step 2 for each gear range. Ensure hydraulic pressure is as specified. See HYDRAULIC PRESSURE SPECIFICATIONS . If hydraulic pressure is within specification, see STALL SPEED TEST table. If hydraulic pressure is not within specification, see HYDRAULIC PRESSURE TEST RESULTS .
