No major problems with it

Reviewed By William K (Chicago, IL) Reviewed for a 2003 Chevy Astro —11/23/2011 6:11 AM

Instruction manual was incomplete; did not have my Astro van listed. Called help number and they helped me. Can't really feel any difference in performance. Haven't checked gas mileage yet.

I haven't measured fuel mileage so far, but shifting is smoother. Very easy to install.
