Sorry to hear you were having the shuddering but glad you managed to fix it. If i was tech savvy i would attempt it as well but since i'm not it leaves me with relying on the dealer. Were the tires you changed just different on width or height as well? Mine were 275/35/20 before and the ones on there are 285/35/20 (just the width changed), and they are the Michellin PS4S which were highly recommended as the best performing tires to put on the car so i went with them. From my understanding you changed your rear tires from the original and then saw TC issues, but then changed your front and it went away? |

Mine are also original on the front and also 285/35/20 on the rear like yours (Michellin PS4S) and had great grip previously, i'm not sure what changed after the transmission replacement. If i was to turn off traction like you do i would probably not be able to drive mine normally as i do. I've also seen people go 305-315 and haven't heard of TC issues previously, even on that sizing but it may be a luck thing. I'm located in Tampa, looks like about 2 1/2 hours or so from New Smyrna Beach. |

By floaty I'm assuming you mean slippery? Like the rear is constantly riding on ice? When your tyres were gripping well, was the weather considerably warmer? Have you tried altering the tyre pressures to see if that makes a difference? What are the pressures at now? Have you checked the tread for nails/stones or other damage? Is it feeling like the throttle input is much higher than what you are applying? I use a throttle controller on my car, and having that makes for a much more aggressive throttle - maybe if the electronics are somehow boosting your throttle signal input, then that's where things are going awry for you. Something easy you can try: open the trunk and pop the little side panel off the passenger side inner. That's where the battery is. Now unscrew the negative cable from the battery, pull it away from the terminal, and leave it to sit for thirty minutes or so. Leave the trunk un-latched (the electronics won't work without the battery connected, so unlocking it also won't work from the outside). Reconnect the battery and go for a drive. See if it makes any difference to the "floaty" feeling. |

Between tire brands, tires showing the same size (275/35/20, etc.) may have different ODs (Outside Diameter). Same goes for contact patch or tread width on pavement. Not all 275 tires are the same width. Another thing to remember is that the second number is "aspect ratio". A 285/35/20 has a different OD (larger) than a 275/35/20 tire. Use Tire Rack charts and see what the ODs and revolutions per mile are for each tire. Also, keep in mind that tire OD changes with wear. So a brand new 275/35/20 has a larger OD than a corded out 275/35/20 tire. There has to be enough tolerance within the electronics to at least allow for these types of differences. Mostly everything falls within a 5%-10% range of tolerance. For example: If your tire makes 775 revolutions per mile and you change to a tire that make 740 revolutions per mile (maybe the same size tire from different manufacturers), your electronics should stand those variations. These are street cars and street tires, not Formula 1 machines and tires.

On the 2012 model, I ended up trading it for 2016 2SS, so this is from memory. The back tires were shot and the front was about 50% left (I don't know how that happens ) I replaced the back with stock size tires at the time and all was fine. Like you I had plenty of tread on the front so kept them. It was about 2,000 miles later the traction control started having fits...front maybe 40% back still 98%. When I shut the car off at the house and restarted all was normal. Within 10-20 miles "Service StabiliTrack" came up and "Reduced engine power" came up. This would stay until the car was shut off. Only way to really move was to take the auto into manual mode and manually shift...still barely run. Shut car off and start over. Changed front tires to stock, new tread, and all was well. About the only other suggestion I have for you is to try placing the car in a different driving mode: Tour - narrow band for TC Sport - medium band for TC Track - wide band for TC Moving to sport mode may allow more variance without setting TC alarms. It would be a temp. fix and not real sure if you can validate anything if the problem still occurs. |

Thanks for the battery tip, i'll definitely give it a try in about an hour and report back to see if anything changes. |

I've been in the market for a 2018 A8 Camaro SS lately but now I'm concerned about all of the things I'm reading regarding the transmission. Are the issues wide spread enough that I should seriously reconsider that purchase?

In terms of reliability, I think you're just unlucky if you have an issue. Chances are you'll be fine and love it. |
