A8 Issue TSB 16-NA-175 2017 2SS
1 Attachment(s)
My Symptoms: Shudder at constant speed going up slight inclines or lower speeds going up inclines.
TSB Symptoms: 1. A shake and/or shudder during light throttle acceleration between 25 and 80 mph (40 and 128 km/h) steady state driving when transmission is not actively shifting gears. 2. A shudder feeling that may be described as driving over rumble strips or rough pavement. Link to the TSB on the corvette site. Other TSBs are for '16 Camaros but this one applies to '17. Hopefully this helps someone else. I've also converted it to a PDF and attached it to this post. http://www.corvetteactioncenter.com/...tate-1324.html I had been feeling a shudder when going up inclines at a steady speed (50 - 65 mph) and had addressed it with the dealer twice. Each time they told me something different. The first time it was because I drive around in sport mode and the second time they told me my engine was lugging and that it was the V4 to V8 AFM that I was feeling. On the third time I lost my mind on the tech and the service manager. I've been working on cars since I was 14. I've owned multiple Firebirds and Trans Ams and most recently a '15 Challenger. I told them that there is an issue with the torque converter and stop feeding me a line of BS, dig into it, and actually spend some time troubleshooting. Prior to this appointment I had done a bunch of searching and that's when I found the subject TSB. It described my issue exactly. I gave them the TSB and what do you know, I have an issue with my torque converter. |
I had this issue. Took it up to the dealer and had one of their guys ride along with me and reproduced it for him. They flushed the transmission fluids three times (driving for 10 miles between each flush) and the car has been perfect ever since. I was told if it started to happen again they would get a me a new torque converter no questions asked.

Dam ! summer time too. Well I'm sure eventually Chevrolet will iron out the issues with that automatic trans.
|
I hope so. I was hoping the '17s wouldn't be affected by the A8 bug but apparently they are.
Really frustrated that I had to lose my cool with them to fix the issue. Sent from my SM-G920V using Tapatalk |
I ran into another guy at a car show and he had the same issues, he said they did the trans fluid flush a few times and it cured it. I'm just not completely sold on that yet.

Well with the money we pay for these cars it's perfectly normal to lose your cool ! Don't blame you one bit but I understand
|
Sorry to hear that you had to go through so much frustration to get this fixed but Thanks for the post! I have felt the "rough road" problem several times with my car running on smooth highway. I wasn't sure what was causing it and it hasn't been consistent enough to take it to a dealer. I guess I will see about getting into the dealer to have it checked now that there is a TSB and documented way to test for the problem.
