:shrug: Nobody want's to take a crack at this one huh? Here's my thinking. An auto will always get worse mpg because of the slip in the t.c.. So if you lock the t.c. and use the torque of the engine to move you at slower speeds in a higher gear there is a milage increase. If you just want to hammer down it's in drive which is regularly programmed. This will shift way faster than you could ever with the tap shift. For low traction conditions you could start out in 2,3,or maybe even drive. A lot of older non electronic trannies have the valvebodies rebuilt to allow total manual shift. Even the tranny (I forget the #, 5r100?) in the 6.0 p-strokes will let you lock out gears up to 3rd. It would be the best of both worlds. Anybody got any take on this?
