So I was bored and found a site that is a free VIN checker, decided to run my car and found a few TSB for my car! Reading through I saw this from 01-21-2004 "01-21-2004 103100 Power Train:automatic Transmission:control Module (tcm, Pcm) B28 and later pcm calibration update information repair information review1 *tt"

Does anyone know what this updated calibration does?!
