## Upshift Clutch Engagement Pressure Feedback

• Clutch pressure (2) is learned so that gear shift time (1) becomes a predetermined target value, and thus changes in performance and changes in the transaxle over time are minimized based on past gear shift results.

1 | Turbine revolution
2 | Clutch engagement pressure
3 | Time

## Upshift Timing Feedback (Release-side Clutch Pressure)

• Clutch pressure release timing on the release side (2) is learned so that the change in engine speed (1) is optimized, and thus clutch pressures on the engagement and release sides are optimized.
