4l60e lockup Besides better gas mileage and for tuning purposes does it have any other benefits for keeping the lock up function. I personally don't like it and am trying to decide if I want to keep it or not.

Or set the minimum and maximum TCC duty cycles to zero (0).

The last time I had my car tuned I had him set the lock up so it only came on when I was on the highway. I think it was set at 65mph. My normal tranny temp. driving around town without lockup is anywhere between 120 to 150 degrees.

When a torque convertor is locked it is most efficient, reducing heat and power loss.
