727 manual vb

I have a RMVB in one of my cars and I love it. I installed a bolt in sprag and got a valve body from Cope racing that has low band apply. Once you get used to driving the reverse valve body its no big deal. The biggest concern with this particular valve body is not to shift back into low until the car is pretty much stopped. If you do the back tires will lock up instantly and you risk shredding the guts out of the trans.
Its real fun to drive, really barks second gear....it hits HARD.
I ran a turbo action RMVB back in the 90's. It was cool but I think the cope VB is much better.
Just think of it as a manual transmission that you don't have to clutch.
