If you are talking about how the shift is accomplished inside the trans, i have no clue. Im not a trans guy.
But any, and all shifts will have to be made by the driver. Reverse mvb, just means that first gear will now be found where D used to be, then second, and third (NOT drive!) will be where 1st was
The idea was so all shifts are away from neutral. You can use a stock shifter, but it probably wont work as well as one designed for a rmvb.
I have two cars with rmvb, one with a stock, but modified column shift, one that used to have a turbo action that i changed to a B&M ratchet shifter.
