    They flipped the ring gear to make the Renault 4141 work in the DMC-12. As far as I know, that's the only internal modification that needed to be done.

    If you're referring to Bob Brandys' "97 DeLorean Time Machine," I believe the computer control was functional, if I heard correctly here: (Apologies if you've seen this vid already.)

    If memory serves, the AR4 was used on the Renault Safrane, but that was a front-wheel drive application. Not sure if the torque converter was locking (ours is non-locking). Also not sure if anyone's tried to install one to a DMC-12; I guess that depends on if you could just take the AR4 and flip the ring gear to make it compatible a la Dunmurry Engineering

    Actually, Nick and Farrar are both somewhat correct.

    Although the shift computer can be programmed, a "best case" mapping has not been able to be programmed (yet).

    The majority of time I have seen the car being driven (by Bob or Gail), the car has been shifted "manually".

    In any case, Bob Brandys (Bob635) will likely chime in here at some point.

    I'm not sure exactly what Bob has planned for the transmission in his New Dream DeLorean Project (2017).
