My 97 auto had 3.27's. Just changed them out friday to the 4.10's.
Was running around 2k stock at 60mph now its about 2350-2400 at 60.

Ok the orange 20 tooth gear is currently installed. The black one your showing is what I need for the 4.10? I need to do this right because my car's speedometer is checked for calibration every two years. Real pain in the ass.
