I recently flashed my TCM with an newer O.S and Calibration. I have a Feb 02' truck and just put my fleece tap-shifter on today. I re-flashed my O.S to 15172881, Cal to 15172884. I looked for and found the newer info here, seems to work fine. It's a few pages further on. Look for posting from GMC-2002-Dmax
