1. Fluid pressure check hole
2. Oil pan

LINE PRESSURE 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 following conditions.
D Automatic fluid is at normal operating temperature (70 to 80_C /
158 – 176_F).
D 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 in trans-
mission case.
