Alright already, I'll try to be helpful this time. This chart shows a TH350 or TH400 (3 speed) 1:1 ratio with the convertor locked and the effects of tire size and final drive ratio on engine RPM (add a couple hundred RPM if the convertor is unlocked). Most manual five speeds have the 1:1 ratio at 4th gear (like the NV4500) and then 5th gear is the OD ratio usually somewhere around .7:1 or .73 or even a little closer to 4th like .8:1. You can use this chart to find your engine RPM at 1:1 (3rd gear for auto or 4th gear for manual) then take that RPM and multiply it by .7 or .73 or .8 or whatever OD your new trans has. That's easy enough right? Sorry for the resolution but it is the only picture I have of this. I think a 700R4 has OD in 4th (it still has 1:1 in 3rd) but I do not know what ratio it is maybe close to .73 or so. Maybe someone else can add that.
