ive been told (damn idea fairies) that an auto with 4:30s is turing the same revs as an manual with 4:10s... is this true ! I have an auto with 4:10s and i rod in my buddys with idetical performance mods with 4:30s and DEAR GOD i was 16 all over again ! just wondering .. thanks !

No, it's the other way around. The auto has lower 2nd, 3rd and 5th (O/D) than the manual.

This is why most say 3.73 for auto and 4.10 for manual as when you do the math, the final ratios are pretty much the same.

 

so 4:10s on my auto are turning what a manual turns in revs on 4:30s..?

 

pretty much, but it depends on the tires too.

 

i have 285s in the rear 18"

 

Ya so a manual with the same tires is like 4.30's. I have 4.10's in my manual, but because I have such a tall tire (295/45) it makes them more like 3.90's.
