RECOMMENDATIONS/PRECAUTIONS : AL4 AUTOMATIC GEARBOX
Precautions to be taken
Repairs on mechanical components.
Never place the gearbox on the ground without protection.
In order to avoid breaking the input shaft ring, it is imperative
that the
converter retaining bracket should be in place when handling the
gearbox.
It is imperative
to use the centring peg and the converter retaining
bracket to couple the gearbox on the engine.
After coupling the gearbox on the engine, remove the centring peg. Modification of the oil usage counter value.
Exchanging the gearbox ECU:
- Note down the gearbox counter value.
- Transfer the value read into the the new gearbox ECU.
Exchanging the gearbox:
- Initialise the oil usage counter to 0.
Draining the gearbox:
- Initialise the oil usage counter
(follow the diagnostic tool procedure).
