The 47re, is still mostly mechanical. All of the shifting except for O/D is still done directly with linkages, and you can tune your shift points to allow you to shift at different speeds. For me Personally, I can throw mine in 1 and it won't shift out no matter what I do, and I can run it up to about 30mph before I run out of RPM. However, I can't downshift from 2 to 1 above 20mph not that I'd really need to. The one that gets me, Is I can't downshift from 3rd to 2nd above 32mph, I really want to be able to make that shift higher so I'm going to see what I can do to adjust my valvebody.
If you get the manual shift valvebody, the problem is, you can't have it work as an auto on the street, manually is the only way to make it work. I would give Dave Goerend a call, and he can get you set up for what you need, either with a valvebody tuned to your specifics or I'm sure he can do a manual shift too if thats what you want. DTT could do the same for you too. In Fact, you may look at upgrading to a 48re valvebody out of one of the newer trucks, because the valving in them allows for much higher line pressure and better holding power.
