Sounds like you have a bad shift solenoid. Not sure if the Chevys are a solenoid pack, or seperate, but it will need to be replaced.

Check the transmission fluid level to make sure it's at the proper level. Have a transmission shop determine with a scanner that if it's your 3-4 solenoid or the wire harness has gone bad and will need to be replaced. You have a 4L60E transmission and this is common if your Throttle Position Sensor (TPS) is faulty and needs to be replaced, easy fix, just replace the TPS on the throttle body. Your Electronic Pressure Control valve EPC is faulty due to dirt from dirty transmission oil and filter, or the solenoid has gone bad or the wire harness on the passenger side by the catalytic converter has gone bad from corrosion or loose. Try disconnect the wire harness on that side and cleaning it out with break parts cleaner and reattaching it to see if that helps before you drop the transmission pan to get to the solenoid. The solenoid is around $45.00 and take about 10 min to replace once the transmission pan is replaced so this should cost around $150.00 repair with the oil and filter replaced also have them replace the boost valve "$45.00" with a 0.490" boost valve to bring up the transmission line pressure to help you get more life from your transmission and should be replaced every 60,000 miles as a part of the transmission service. Good luck and keep me posted, be glad to help you get your transmission running 100% again soon.
