Does anyone know what the gear ratios are in the T-5 and the AOD? Any help would be appreciated. I am looking for the ratio's of each of the specific gears first through fifth and reverse (I.E. 2.5:1,0.68:1, etc.).

I am doing a design project in which I have to come up with the gear ratio's for a 4-speed transmission. The vehicle speed is from 0-100 and overdrive is needed for fuel economy. I realize the t-5 is a 5-speed and the AOD's overdrive acts as a fifth gear.

Also, if anyone has links to where I could get dyno figures for stock 302's it would be much appreciated. I figured I would ask you guys instead of rifling through five voulumes of MM & FF. I was assigned dyno specs for a 3412C Caterpillar marine engine, but the instructor said we could pick an alternate engine as long as we found dyno #'s and graphs so of course what better engine than the 302.

Thanks
