Does anyone know the stock rear end ratio in an SC300 auto? Also what is the min and max voltage that the 1JZGTE TPS reads??

Sorry, I hope someone can explain this to me.. as i know absolutely nothing about ratios/rear ends... Im guessing the lower the ratio the better?
I have an auto SC, and i plan on dropping a 2JZGTE in her, and also doinig a standard w58 swap. Should I also swap out the 5speed rear end? what about drive shaft? Will I be fine/safe using the auto rear diff/shaft? Should I just look for a TT reardiff/shaft?

Think of gear ratio's this way.
The lower the # the lower your rpm in top gear @ a specific highway speed.
Just a example:
3.00 = 2,100 rpm
4.00 = 2,800 rpm
In the opposite view, the higher the ratio # the more "pull/ launch" off the line.
But your distance/ mph in 1st gear will be shorter/ lower.
In general for a "swap" if the ratio's are reasonably close you'll be fine unless
you are looking for a "race" set up.
I can't comment on the SC auto rear w/ 5peed trans set up as I have never
driven this combo. Although there are a lot of people here that do run this.
In theory 1st gear may be a little short, & rev a little higher on the highway.
