1. PERFORM HYDRAULIC TEST





(a) Measure the line pressure.

NOTICE:
* Perform the test at the normal operating ATF (Automatic Transmission Fluid) temperature of 50° to 80°C (122° to 176°F).
* The line pressure test should always be carried out in pairs. One technician should observe the condition of the wheels or wheel stoppers outside the vehicle while the other is doing the test.
* Be careful to prevent the SST hose from interfering with the exhaust pipe.
* This check must be conducted after checking and adjusting the engine.
* Perform with the A/C off.
* Do not conduct stall tests for longer than 5 seconds continuously.
