RPM at 70MPH

Thanks or all the input. This was a huge impact on my decision. I was initially going to go the wrong direction. I thought I was going to go with a 3.73, or 3.9ish.

Figuring in TC slippage into my rpm equation, I will probably go with 3.55 or 3.23

3.23=2300 at 70

Again, thanks!

The 545RFE has a lockup converter. ie no slippage at cruise. How tall are your tires?
