Depending on driving mode, engine load and vehicle

speed, the torque converter lock-up clutch is first

regulated with a minimal slip and subsequently

completely applied. During regulated operation, fuel

consumption is reduced when compared to a released

torque converter clutch and driving comfort is

improved compared to a fully applied clutch. Refer to

the chart in Figure 31.

Using Tiptronic in “S” mode, the torque converter

lock-up clutch is applied as soon as possible. The

direct power connection between the engine and

transaxle improves the "sporty" driving feel.

In a climbing mode, the torque converter lock-up

clutch applies in 2nd gear.

When ATF temperature is above 130º C, the

regulated apply feature is prohibited and an

immediate apply occurs. This helps in cooling the

fluid down to a normal operating temperature.

Refer to Figure 31 for the location of the torque

converter identification code.
