Thanks to Fieroguru for the charts! I was looking for info on the G6 F-40 trans, as I have found one for relatively low cost.
As I am replacing my 2.5l Tech 4 with a 3800, I want to get a trans that will last a while, but I have limited budget to get it done.
If I am reading the charts correctly, a Getrag is the standard, any trans above the Getrag has a low gear ratio, any below have a high gear ratio.
The gear ratio affects both the launch and cruse RPM, and drag racing you want a low gear to launch quickly, and for fuel economy, you want a high ratio. But just how bad is the Pontiac G6 with the 3.55 final drive ratio? The info I am needing is the RPM of the car while cruising in 6th gear, and the first gear performance. I found opinions covering the spectrum, but not hard data.
As I am used to a SBC coupled to a differential with a 3.90:1 gear, the low gear was quick, and the cruise RPM was 2500 RPM at 60 MPH. But I doubt the F-40 has the same feel as the 3.90 gear in my Nova! The cruise RPM, I suspect, will also be lower, by a bit!
