Re: trans gears

I do not think anyone makes alternative gears for the 700r4. The 200r4 has a better spread though.

Re: trans gears

I just bought a BTO transmission and they say it has 3.06 first gear which they say is 20% lower. I have no clue what the factory gears, I just remember reading their website.

Re: trans gears

Factory 1st gear in a 700 = 3.06

I have no clue what that might be "20% lower" than.... a 350 maybe??
