So I noticed that the tranny in my '03 Silverado 2 wheel drive is acting fruity. I have only had this truck a couple of months and don't know if the following information is a "normal" thing... It seems to slip into Neutral between 1st and 2nd gears. It will also allow the engine speed to go really high before shifting from 1 to 2. If I drive it REALLY easy, it seems to shift fine... The tranny shop told me it needed a sprague gear replaced to the tune of about 1700 bux after driving it around the block. I have read postings from others who say that they went to the dealer and had the computer re-programmed which fixed it. So my question is... Is my tranny busted, or does the computer just need to be "re-programmed"?
