I want to try and figure a mapping for the Torque converter lockup clutch. We already have a good idea for the center differential. At first I will manually controll the lockup to find a setting that allows a small amount of slip when a gear shift occurs.

If your curious why, depending on the amount of information I can find I will either create a center diff/torque convertor controller (like torquemada) or a complete transmission controller. If you look at the diagrams for the pre99 transmission its a fairly simple device.

I think the stock setup only uses two duty cycles (5% and 95%) and only uses intermediate values to avoid drivetrain shock.

In this thread I wrote what I could gather from the FSM:
