Control of Shift Operations With Electronic Synchronous Shift Control

In the automatic transaxle, electronic synchronous shift control is used.

Electronic synchronous shift control monitors the shift operations and is able to adapt to the wear in the shift elements over the life of the transaxle.

This is possible since the shift elements are actuated by modulating valves.

The system monitors the shift time whether the shift operation is synchronous.

If the PCM detects a deviation from the stored values for the shift time and synchronization of the shift operation, the pressure buildup or reduction is adapted accordingly.
