AUTOMATIC TRANSMISSION (4 A/T) 7B1-39
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.
•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
3) Depress foot brake fully, run engine at idle and stall.
4) Check fluid pressure in “D” or “R” range within the following
specification.
Line pressure :
5) If check result is OK, disconnect special tool, then tighten
transmission case plug to specified torque.
Tightening torque
Transmission case plug : 17 N·m (1.7 kg-m, 12.0 lb-ft) CAUTION:
After attaching oil pressure gauge, check that not fluid
leakage exists.
CAUTION:
Do not continue running engine at stall speed longer
than 5 seconds.
