Does anyone out there have info on the gear ratios on a NP 540 trans. I know some of these units are overdrive, some arent. The first gear ratio determines whether or not it is an O/D, but I can't find info about the other ratios, or whether mine is O/D. 2700 RPM at 70 mph in 5th gear with a 3.54 rear gear along with really tall tires can't be O/D ing. I'd really like to know what all the ratios are in this trans, not just what fifth is. My trans is a 7.41 :1 first. Any ideas? thanks a lot.

I "Googled" NP 540 just about every combination I could think of. What did you do that I didn't? Thanks a lot for the info. I've gotta decide what to do with this thing, this trans just isn't working out with my engine and truck combo. This will really help.
