03 auto v6 Gears

I'm very interested in getting gears but i don't know what to go with I'm stuck between 4.10s and 3.73 only problem I have with 4.10s would be revving too high on the highway was wondering what everyone thinks I should go with

Generally for auto it's 4:10 and manual it's 3:73. I think 4:10s run like 500rpms higher than normal but i dont think it hurts gas mileage that bad.

This will give you a better idea of the difference in rpms.

With stock 3.27 my gt turned roughly 2k in fifth at around 75mph. With 4.10s it turns around 2.3k at 75mph, or 2k at 65mph.

Cruise at 65-70mph and your mpg doesn't really change that much, if your car's tranny is like mine. I'm posting from my phone so idk which section this is in.

Re: 03 auto v6 Gears

4.10s for auto helps even out the worse gearing the autos have vs manuals... but the final drive auto vs manual is close so you will have a higher final drive rpm. Your gas mileage will suffer~ and you will run through your gears very quickly~ just part of it. I probably would go 4.10s in an auto if it was me.... but either will help.
