Line Pressure Test

Test
Purpose of this test is to check operating conditions of each part by measuring fluid pressure in fluid pressure line. Line pressure test requires the following conditions.
^ Automatic fluid is at normal operating temperature (70 to 80°C/158 - 176°F).
^ Fluid is filled to proper level (between FULL HOT and LOW HOT on dipstick).
1. Apply parking brake securely and place checks against wheels.





2. Attach oil pressure gauge to fluid pressure check hole (1) in transmission case.
Special tool
(A): 09925-37811-001

CAUTION: After attaching oil pressure gauge, check that not fluid leakage exists.

3. Depress foot brake fully, run engine at idle and stall.
