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.

Maximum engine speed for ES9A

Maximum engine speed for DT17

: D.

: 2400 50 rpm.

: 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.
