So, I have modified the automatic to lockup the Torque Converter at the flick of a switch -- if started in 2nd, it has been possible to stall the engine and override the ECU/TCU.

With that said, I have wondered the same about lugging. Typically, I can get the revs down to 1100, which maxes engine load and has been noted to warm-up the vehicle quicker than slipping with the slush (or even lower with 2nd-gear start). The best feature is the throttle lift-shift that generally produces more of a vibration than "lug". To engage full lockup, it requires significant throttle input -- which is a give-and-take. Transmission warmup is faster as well.

FE has improved with the mod, but with Winter, the percentage is hard to estimate. The benefit of essentially having a "heavy manual" is nice.
