If transmission to the ACPR is delayed (shift of gear shift occurred), this may be caused by:
(1) The speed sensor of the output shaft of the box shall not be used.
(2) The throttle position sensor is not in use.
(3) One of the electromagnetic valves has failed.
(4) The pressure in the automatic-box control system is not nominal.
(5) The ACPR control unit has failed.
If only some transfers are not being done in time, the likely cause is a failure of the control valve assembly.
