I had service done at 12,000 and told chevy dealer that my transmission was not working properly, around 40 when driving in town it shifts up and down a lot, hard clunk sometimes when shifting from reverse to forward. The dealer said that they had installed the wrong fluid and that they would change it. Has anyone else had this problem. I have not had the fluid changed as of yet, I was wondering if that is just a ruse.
