U151E AUTOMATIC TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: HYDRAULIC TEST

1. PERFORM HYDRAULIC TEST





(a) Measure the line pressure.

NOTICE:
* Perform the test with the ATF at the normal operating ATF temperature: 50 to 80°C (122 to 176°F).
* The line pressure test should always be performed with at least 2 people. One person should observe the condition of the wheels or wheel chocks while the other is performing the test.
* Be careful to prevent SST's hose from interfering with the exhaust pipe.
* This test must be performed after checking and adjusting the engine.
* Perform the test with the A/C off.
* When conducting the stall test, do not continue for more than 10 seconds.
