IF I could post a picture here with out a damn URL I could show you the charts of the transmissions RPMs in each gear from 500 to 5000 with the gear sets I want.

IN each case the first gears of the 6 & 8 speeds are running higher RPMs at 10MPH that the stock transmissions with the stock rear end gears. So the lower first gears are making MORE Power even with a 2.26 or a 2.47 than with the stock 3.27 gears.

So the numbers show a slightly higher performance off the line than with the stock transmissions with stock rear ends.

And at this time I am very happy with each vehicle's power off line and driving. This will just improve it.

I end up with more gears up to cruse and a very high final gearing.

From 1600RPMs to 2000 RPMs with both vehicle's.
