I would definetly put the gov in it. no doubt about that. The high rev gov will make it shift at about 55-5700 rpms in D on the 1-2 and 2-3 shifts when you put it to the floor boards and hold it there on it's own. In OD it may raise it a couple hundred but not as much as in D. My tranny really comes alive when it's locked D. I too plan on a hammer shifter but with the stock shifter and shifting it on my own, at the track it was more consistant, shifts felt cleaner, and the car was faster letting the tranny do it's job on it's own. I can't say enough about the gov. I really like it even with a hammer shifter I see a place for the rev. gov. IMO. It's nice to be cruising on the street and drop it into D and hammer it down into second and let it rev up to about 5700 to shift into 3rd compared to the stock 48-5000 rpms. To be honest i bought the car with the AOD so the wife could drive it and the tranny blew out 700 miles later. I decided to to spend some cash to rebuild it with good internals, converter, and transgo and although I would have probably gone with a 5spd if it wasn't for the wife, I really am liking this AOD now.
