When I installed my shiftkit and shifter the 1-d-1 shift was in the instructions on how to shift from B&M. Lentech Auto has a valve body that locks out OD and changes the shift pattern to 1-2-3 then hit a switch for OD. It is also supposed to increase the torque that the tranny can handle and "extend the life of the AOD." I will find out in two weeks.

It's about $349 though.
