HI:

Try this I had a few Corvettes with this problem. Remove the wiring connector on the right rear of the transmission and reinstall. Sometimes the connection can be weak. Be careful the connector has a lock then twist.

Check the number one fuse under the hood or it might be number 3 fuse for connection I can't remember which right now. Which ever says TCM.
