●
This malfunction will not be detected while the A/T CHECK indicator lamp is indicating another self-diag-
nosis malfunction.
●
This malfunction is detected when the A/T does not shift as instructed by the TCM. This is not caused by
electrical malfunction (circuits open or shorted) but by mechanical malfunction such as control valve stick-
ing, improper solenoid valve operation, etc.
