what gear ratios should i get in my new built AOD first and second ratios?

It depends on your rear axle ratio. If you have 3.55s or 3.73's (or 4.10's, then DEFINITELY), then i'd get a lower than average ratio. That will give you an extra 2-4 MPH an 1st and 2nd gear, which will help with your ring and pinion. If you have a high gear ratio in your rear axle (2.73, 3.13, whatever) then go stock or higher.

thats not what he asked at all

stock, the aod is 2.40 in first and 1.47 in second if memory serves. i think the only other choice you have is the wide gear set which is about 2.80 in first and 1.60 in second

It's exactly what he asked. Maybe you misunderstood. I put the wide gear set in my AOD, which is a lower ratio in 1st and 2nd than the stock (thanks for posting the numbers). As I said before, if you have low gears in your rear axle (3.55-4.10), then get the lower ratio gear set (wide gear set, as you called them). That becomes beneficial when you have the low gears in the rear axle, becuase the wide gear set gives you an extra 2-4 mph in 1st and 2nd gear. However, like I said, if you have high rear end gears (2.73-3.23), then it would be more beneficial to stick to the stock gear set.

See?

yeah the widegear set is 2.84 1st, 1.55 2nd and only other options i know of, it's the mark VIII stuff

i'd go w/ it......the whole kit gives better clutches and better od band too, so check it out b4 you end up w/ a bunch of extra parts.

assuming it's a DD or more street than strip, i'd do wide gearset, 3000 stall (precisions stallion) , and 4.10's

not so much street than 4000+

Wherecan you get a wide ratio set??

A transmission shop or a racing trans rebuild place.. the place near me is called trans parts plus. You can probably order it online too.

ford-aod.com has the kit
i think you can get it straight from ford racing. its basically just the 4r70w gears

so will the widegear set make my car perform anybetter on the 1/8th ive got 3.73's if its not more than .2 of a sec then forget it.

it would make a good diffences. having the wide gear set plus 3.73 in the rear is the equivalent to have the stock tranny gears and 4.40's in the rear. second gear with the wide gear set with 3.73 in the rear is the equivalent to having the stock tranny gears and 3.93 in the rear. 3rd gear is untouched so it will still be the same.....3.73 and so will OD. 4.40 and 3.93 are really low, if you have stick tires and good suspension you will see a huge change coming off the line. thats the nice thing about the wide gear set is that it makes 1st and second gear really low when combined with 3.73's in the rear yet 3rd and OD are untouched making them high enough for street use
