Transmission Ratio Question? Help!
 

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

all I know is that the 5th gear in the t5 can be taller than the OD gear in the aod. The t5 is like .68 and the aod is .67

Yeah after I posted I found a bunch of websites with various gear ratios, so if you guys don't know off hand its not a problem.

BTW, Stng87 you are correct the t-5 is 0.68 and the AOD is 0.67. Thanks
