1.
Warm up the engine until the A/T fluid temperature is
70 – 80
C.
2.
Jack up the vehicle so that the wheels are free to turn.
3.
Connect the special tools (2,942 kPa oil pressure gauge
[MD998330] and joints [MD998332, MD998900]) to each
pressure discharge port.
NOTE
2ND: Second brake pressure port
UD: Underdrive clutch pressure port
LR: Low & reverse brake pressure port
DR: Torque converter pressure port
RV: Reverse clutch pressure port
OD: Overdrive clutch pressure port
4.
Measure the hydraulic pressure at each port under the
conditions given in the standard hydraulic pressure table,
and check that the measured values are within the standard
value ranges.
5.
If a value is outside the standard range, correct the problem
while referring to the hydraulic pressure test diagnosis
table.
