I know there are full manual valve bodies available for the 4r70w just not sure what the advantage is
I believe that means you would have to do the shifting from 1-2 and 2-D
D is then 3-4, TCC and OD, The OD can be controlled with the OD on and off button
Because you asked I am going to research the MVB for a 4r70w....peak my curiosity
I am sure the USshift Optishift can handle that even the stock PCM can handle that.
My 4r70w (88 bronco II) uses a floor shifter with the gates filed out so the shifter will hold 1st gear or 2nd gear until I release it.....very nice for holding back on hills/rocks
Before filing the detents for the shifter gates the trans would auto shift from 1-2 and 2-d, meaning when you hit redline the shift lever would actually move to the next gear! I could not believe it, the mustang dudes actually drive like this? So filing the gates stopped this and now I can hold 1st gear for the whole trail, or second, or put in D and the trans does all the shifting. With a MVB when put in D you would only have 3-4, TCC and OD, so you would always have to do the 1-2 and 2-d Shifts and D-2, 2-1
Brett (High Plains Performance) is a USShift dealer and my trans builder, he is a 4r70w expert these days...........so if you want to order something let me know I put you in touch with him.
