Well, for all of the disbelievers, my 3.5 2002 R/T spins 2000 RPM at 60, also. Does this mean that I might actually have the 3.89 gears? I think that the 6% gearing difference would mean my car would spin 1880 RPM at 60 MPH if I didn't have the 3.89 gears. Please post back that it's impossible, wrong, can't be, etc. Maybe we could create doubt about the tachometer, on my car or on alarkyokie's vehicle. I recently read in the posts that someone has a gray R/T, even though Chrysler says they don't exist. Maybe I have the 3.89 gears, even though many "experts" at dodgeintrepid.net tell me repeatedly and condescendedly that it's impossible. Or maybe they are right? What does their 3.5 equipped car spin at 60MPH?
