Line Pressure Test: Preparation

This test measures line pressure as a means of checking hydraulic components and inspecting for oil leakage.

1. Engage parking brake and put wheel chocks at front and rear of each wheel.
2. Warm engine thoroughly to raise ATF temperature to an operating level of 140~158°F (60~70°C).
3. Check and correct as necessary, engine coolant, engine oil and ATF levels before testing.
4. Connect a tachometer to engine.
5. Remove splash shield under front left bumper.
6. Connect SST (0K201 190 AAO) to line pressure inspection port (square-head "L" plug). It may be necessary to raise car to get at inspection port.
