Hey guys well i went to go buy my first duramax and when i went to test drive it, it would not go when in any of the gears until you gave it some throttle kinda almost like have a stall converter but i know that isnt the case. Turns out it was this Park/Neutral switch that is suppost to be located on the side of the tranny, I am not completely sure I am still wet behind the ears on all this stuff so any insight would be wonderful. Also is this just the start to a wonderful disaster should i stay away from this truck. Mileage is 269000 miles and its a 2004. PLEASE HELP!!!!
