GEARBOX
TRANSMISSION
CHECKING THE OIL PRESSURE IN THE AM6 AUTOMATIC GEARBOX
Checking the torque converter.
WARNING: This check has to be of short duration (2 seconds), as it causes a rapid
rise in the temperature of the oil in the automatic gearbox.
Respect the following checking conditions:
- Engine at operating temperature.
- Gear lever in position D.
- Press on the brake pedal.
- Accelerate the engine to the maximum engine speed (see below).
Gear lever position.: D.
Maximum engine speed for ES9A : 2400 ± 50 rpm.
Maximum engine speed for DT17 : 2600 ± 50 rpm.
Diagnosis:
- If the maximum engine speed obtained is lower than the value indicated, the torque
converter is the cause.
- If the maximum engine speed obtained is higher than the value indicated, the automatic
gearbox is the cause (slipping).
Additional operations.
Remove tools [1]and [2].
Refit the screw (2), with a new seal.
Reposition the pipe (1).
Refit the air filter housing.
