Hi my name is ***** ***** I'll be more than happy to assist you. You need to check the transmission fluid. make sure its full, reddish color and doesnt smell burnt. If that is all okay, you need to have the transmission control module scanned for fault codes.

Hi David and thanks. If there were codes in the transmission or its module wouldn't I have the check engine light on? It is not on at this point
Chevy Mechanic: david craig, Auto Mechanic replied 8 months ago

no you would not. transmission fault codes do not turn on the check engine light. the transmission control module has to be scanned with a scan tool that has the capability of interrogating the transmission control module

I have a couple different vehicle scan tools I'm not sure what they're all for maybe the same thing I don't know but I'll Google them and find out if any of them are for the transmission and thank you
