I was recently informed by a master mechanic that shifting the automatic transmission starting in 1st gear through 3rd gear was harmful to the transmission if you do this on a regular basis. I have worked on pickups for over a decade and have yet to hear of this. Does anyone know if this is true? If so any links with info as to why?
