2002 Chevy silverado, at speeds of 60+ mph, it feels like the transmission slips or it sputters(hesitates), but only at high speeds


Are you certain that it is the transmission and not the engine misfiring? I would recommend scanning your onboard computer network to BEGIN proper diagnosis.

Hesitation, misfire or "bucking" feeling


you most likely have a coil pack going bad.
This can cause an electrical spike and cause computers to reboot just like your home PC in and electrical storm,that is why the transmission acts as if it does not know which gear to go in.
You need to have someone hook up a scan tool and retrieve the trouble codes and see if there is a miss-fire code stored in memory.
