Hi Brandy, No thoughts yet, but if you list the actual trouble codes I can get a better idea of what is happening. The codes are universal, but the code message (i.e. "tcc sol") are not. You should avoid operating the vehicle until it is sorted out. If you choose to take it in, it is best to have it towed, just in case. Two links will help you here: http://repairpal.com/chevrolet-within-10-miles-of-brattleboro-vermont-05301 That will show you certified shops in your area, and: https://repairpal.com/symptoms/check-engine-light will help you understand the trouble codes better, and show you what they may mean.
