at 52 mph and 2000 rpm the car hestiates, goes to 1800 then to 2300 rpm

scan for codes

no codes showing .....CVT trans FAILURE may 24 [ 2 months later] at around 61,500 miles.... looks to me like this CVT trans is designed for typical failure at 102,000 miles and can fail with normal driving conditions as early as 60,000 miles and as late as 142,000 miles or somewhere near these numbers.....no codes or check engine lights and I even had a mechanic take it for a drive and he could not detect anything... almost looks like chevy knows the trans will fail and when u take it in there is nothing they can do except charge you money until complete failure and then replacement
