If the automatic transmission car jerks when accelerating and the dash does not indicate a gear, there is a problem with the transmission. Check the shift solenoid.
A clunking noise when shifting gears on a K1500 automatic transmission, might mean a problem with the drive axle or drive shaft. Check all U-Joints to make sure they are working properly.
Your transmission is "sticking" sometimes a fluid and filter change can resolve this problem for a short time however is this does not help there is a solenoid in the trans that needs replacing any transmission shop can preform this solenoid swap relatively cheap and most have the capability to diagnose this problem for free
