The 6-peed transmission in the 2009 Sierra “stutters” or “slips” when shifting gears at low rmp. Neither the dealer nor a reputable local transmission shop can identify the problem with any certainty and it seems to be getting worse. It is most evident when the transmission temperature gets above 150 degrees. I bought this truck a week ago with no warranty and am extremely concerned the transmission may take a dump on me in the near future. Appreciate any info anyone may give with regard to this issue. Thanks, Bill ---

Was the transmission fluid ever replaced? If not, get it replaced ASAP ---

Yup, fluid and filter change in a heartbeat. It may fix it, may not. But it doesn’t cost much to try.
