This kit really brought my Allison into line. Crisp, fast shifts. Slip is virtually nonexistent. Installation wasn't the easiest, but well worth it. Unless you know transmissions, you SHOULD NOT attempt to install this kit as it is VERY involved! Pay the pro's to do it. It's worth every penny

Nice short,firm, crisp shifts. Trans hold much more power than stock without slipping.
