    Ken1017, very unfortunate to read your continued problems with your 2015 C7. Your first post back in January 2015 was so positive "First Vette 1953 (my Dad's); my 1st: 1963 FI coupe; current 2015 C7 Z51; I am 73 y/o, will always have a Vette; keeps the juices flowing!!!" and then apparently nothing but a string of unresolved issues. I strongly suggest you send a PM with your VIN, a description of the issues and which dealer you have been dealing with to our dedicated Chevrolet Customer Care team at "ChevroletCustomerCare" to ask for their assistance on your behalf.

    Thanks for your thoughts and feelings, my cars are always in pristine shape, engine too. Now to have all the guts ripped out (eventually) is heartbreaking. Will see what they say before I ask for help.

    You guys need a new torque converter. My dealer had never replaced one so my car was in the shop for over 30 days as they waited for "guidance" and parts. I also needed a new fuel pump so they had to completely disassemble the rear of the car including the torque tube, rear axle and transmission. It was all put back together and now it runs much better. Try to find a dealer that has replaced a torque converter. There is a TSB out on this issue. Good luck.

    sudder issue got worse

    Follow up to previous article: It's sitting apart at the dealer waiting for parts or when they can get to it. Not much info from the dealer other than the tranny might need to be flushed several times, over a period of time, to remove contaminants. I am concluding there are worn or damaged parts, so am reluctant to even drive any distance for fear of being stuck somewhere. BTW, car is still under warranty. At least this time they are looking into the issue, not just reflashing a module and sending me on my way only to return with the same issue or more. It's a 2015 Z51, but what good is a hi tech masterpiece that can't be serviced. This might be my last Corvette, first was a '63 split window, sebring silver FI

    The TC issue in this thread has reared its ugly head in my 2016 C7, A8 with a little over 7,000 miles. Took it in at 7,571 mile. Dealer flushed the transmission mission 3 times but it did not fix the issue. Did GM fix the problem "Tuner Boost"? No update on this thread since 2014. Is GM listening? Need suggestions on dealing with this issue.

    Document everything. Make sure you get this resolved before you run out of warranty. Pressure the situation, and let GM know, in writing, that you need help. Work for a solution with them, but, like I said, document everything just in case it does not get fixed. You want to make sure you have all of your information organized if you ever have to go the buy-back (or lemon law) route. Hopefully GM corporate will get involved and get it totally fixed so it will never come to that. I am sure you know of the saying "Hope for the best, but prepare for the worst."

    I am sorry your problems are occurring. I would return to your dealer, gently explain that what they did last time has not worked, and they need to fix this, to succeed this time.

    In your "hip pocket," if they do not, I would next recommend you proceed to exactly follow the procedures outlined in your Owners Manual, sections 13.1-13.3.

    We all hope that this is not necessary, that they fix it right this next time.

    Ronjon, I had a torque converter problem on my 2015 Stingray A8, with 3400 miles. I had the familiar symptoms, bouncing tach, running over rumble strips feeling, etc etc. The dealer service I purchased it from said, after a test drive, "that's just the AFM working". I could immediately tell they were unable or unwilling to solve this issue. I called Stingray Chevrolet, a 50 mile drive from me, took it there and their service manager barely got out of the parking lot and returned stating that I needed a torque converter. They repaired the car in less than a week I have had zero problems since. They sell about one Corvette a day so they do a lot of service work. My repair happened in May of this year. I wish you luck repairing your car.

    Torque converter shudder

    elegant, rdslon01, and vetstings, thanks for your responses. I will, most definitely, follow your suggestions. I bought my vette from Stingray but didn't want to drive it that far. Autonation was recommended by several vette owners so they have the first shot. When I took it in they seemed o know it was the TC. It was confirmed by the PICO test. I sure hope they are right.

    Well, get this: they finally decided to replace the TC but in doing so, the tranny fell off the cradle it was supported on, so I got a 'new' tranny because they cracked the housing. Not sure how 'new' as it does not shift correctly. When cold or when accelerating quickly, the engine speeds up but does not go into the next gear right away. Then when it does engage you get a good jolt. First vette was a 63, I think this is my last. Love the car, hate the service and the run-around. Have had other issues, they tell me that they needed to reflash the memory, which does not work,. A sad ending to fun times.

    I feel your pain, ken. I am also disappointed with my first and maybe my only Corvette. Reliability has been poor and GM's attitude leaves a lot to be desired. My car was in the shop for over 30 days with fuel delivery and tranny issues. I've never experienced this with any car I have owned in my life. Hopefully your tranny will improve as it "learns". Good luck, my friend.

    I took the car in two weeks ago for the shudder and rpm fluctuation problems. The tech and I took it for a test run and it shuddered and the rpm fluctuated. I was in the passenger seat and was able to observe that the fluctuation corresponded with the shudder. I left the car for diagnostics, expecting that the triple flush of the torque converter would be the solution. Not so. Bowling Green told them the torque converter was the problem and to replace it. That is major surgery as the rear bumper is removed and the rear drivetrain is completely removed and put on a bench. Not only does the car now have a new torque converter, it also has new bolts to hold it together and a new cable running to the gear shifter. I suspect the torque converter is a new vintage, i.e. part number. The tech drove it for 50 miles to check it out and all went well. I have it back and it is running better than ever. Thanks to the team at Parks Chevrolet of Augusta for solving the mystery.

    Well my TC problem is back at 12,871 mile. The SA said the TC was under warranty but the new fluid that is required was not. Estimate on the fluid was about $300+. Any thoughts? What should I tell the SA. Suggestions would be appreciated.

    What a crock of BS. GM has a TSB out that says dealers are to change the fluid and if that doesn't work, replace the TC. Both should be covered. I would be on the phone to GM or talk with the Service Manager at your dealer.
