Hey everyone, new to the forums but not new to these trucks. I've owned a 98, 99, and now my 03 Silverado, all 1500's with the 5.3L engine. Now on to my problem. My 03 has just hit 110k miles and the transmission is starting to feel sloppy going from first gear. After the initial take off it will hesitate for a second before shifting to second gear. Its almost like the computer is not telling it to shift at the right RPM's. This is the only gear that this happens in which leads me to believe that its not that the transmission is going out, but that something is wrong with it. The fluid has been flushed and filled early in 2009 (around 20k miles ago). I'd really rather not have to replace the entire transmission, just wondering if anyone else has has a problem like this before. Thanks for any and all the help!
