I have the same ratio and couldn't agree more about the 4.03 first. That is my main gripe. I was sold a V8 trannie that turned out to be a V6. I have a 3.73 rear end so we shift out of first at 10 mph or less. We also spin those skinny wide whites more than we intend. You ought to try and drive up car ramps on a wet driveway.
