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 to 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.

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

3) Depress foot brake fully, run engine at idle and stall.
4) Check fluid pressure in "D" or "R" range within the following specification.

CAUTION: Do not continue running engine at stall speed longer than 5 seconds.





Line pressure for G16 engine model





Line pressure for J20 engine model





Line pressure for H25 engine model

5) If check result is OK, disconnect special tool, then tighten transmission case plug to specified torque.
Tightening torque
