I have an '06 2500 and had the check engine light come on. I have noticed that it sometimes stalls a bit in second gear and then shifts to third a little hard. I was getting new rotors on today and had the tech check the code for me. I cant remember the actual code number but do remember that the code was Output Speed Sensor. This was the only code that came up. Is this something that I can do myself or do I need to pay the 100.00 to get it done? Thanks and any and all help will be appreciated. I am not that mechanically inclined to say the least but I do change engine oil when need be
