HYDRAULIC PRESSURE TEST
I A CAUTION I
The transmission fluid temperature shoul d be between 70
- 80°C (158 - 176°F) during the test.
1. Check the transm ission fluid level and temperature. Check
engine coolant temperature.
• Transmission flu id level: "HOT" mark on the dipstick
• Transmission fluid temperature: 70 - 80°C (158 - 176°F)
• Engine coolant temperature: 80 - 1 oooc (176 - 212°F)
NOTE.
DR: Torque converter output pressure port
PR/: Primary pressure port
PL: Line pressure port
FWD.· Forward clutch pressure port
REV: Reverse brake pressure port

4 . Restart the engine.
5. Check that there are no leaks around the special tool port
adapters.
IAWARNING I
For safety, operators must not stand in front of and at
the rear of the vehicle during this test.
6. Measure the hydraulic pressure at each port under the
1'£507200 AB
conditions given in the standard hydraulic pressure table,
and check that the mea:sured va'l ues are with in the standard
value ranges .
7. If the pressure is not within the standard value, stop the
engine and refer to the hydraulic pressure test diagnosis
table.
8. R.emove the O-ring from !he port plug and replace i,t.
9. Remove the specia l tool, and install the plugs to the
hydraulic pressure ports.
10.Start the engine and check that there are no leaks around
the plugs.
 Con nect the special tools (3.0 MPa (435 psi) oil
pressure gauge [MD998330), 15MPa (2,715 psi)
power steering oil pressure gauge" [MB990662"] and
joint [MD998331 , MB992127]) to each pressure
discharge port.
NOTE:*: Before measuring the primary pressure or
the line pressure with the transmission range at P or
N, replace the gauge of the power steering oil
pressure gauge (MB990662) with the gauge of the oil
pressure gauge (MD998330) .

HYDRAULIC PRESSURE TEST
I ACAUTION I
The transmission fluid temperature should be between 70
- 80"C (158 - 176°F) during the test.
1 Check the transmiission fluid level and temperature _Check
engine coolant temperature.
• Transmission fluid level: " HOT" mark on the dipstick
• Transmissi on fluid temperature: 70 - 80°C (158 - H6°F)
• Engine coolant temperature: 80 - 100°C (176 - 212°F)
2. Raise the vehicle so that the wheels are free to tum.
3. Connect the special tools (3_0 MPa ~ ~ :l:§11)
gauge [MD998330], 15 MPa (2,175 psi)
pressure gauge• [MB990662'l and joint [
998331 ,

NOTE: *: Before measuring the primary pres re or the line
pressuro with the transmission range at P or , replace the
B990662)
gauge of the power steering oif pressure gauge
with the gauge of the oil pressure gauge (MD998 30) _

For safety, operators must no,t stand in front of and at
the rear of the vehicle during this test.
6 . Measure the hydraulic pressure at each port under the
conditions given 1in the standard hydraulic pressure table,
and check that the measured values are within the standard
value ranges .
7. If the pressure is not within the standard value, stop the
engine and refer to the hydraulic pressure test diagnosis
table,
8. Remove the O-ring from tie port plug and replace it
9. Remove the special tool, and install the plugs lo the
hydraulic pressure ports.
10.Start the engine and check that there are no leaks around
the plugs.
