I don't get the fascination with manual valve bodies.
Why not get a proper manual gearbox instead? 3 pedals are too confusing?

Had a reverse MVB in a mainly strip-only '71 Dart years ago. While it was 'secure' shifting on the actual strip, it felt cumbersome in every other situation.

Besides that, I can manually shift just fine in any automatic transmission I have, even the pushbutton ones.
Heck, I pretty much keep the A518 in my daily Dart in 2nd gear most of the time during city-driving, unless the situation lents to use 3rd or OD.
Whenever I don't like manual 'labor', I just put it in Drive and enjoy the ride evenso.

If you want sharper shifting, you need to install a TransGo Reprogramming kit that takes any slip out of the trans.
