Stepping up
Looking to step up to a C7 from a 99 C5. Trying to dig into the transmission issues with the auto and search and YouTube aren’t much help in determining the breadth of the problem. Flush the fluid, torque converter failure, etc? I’m looking to understand if this is a pervasive problem of a bad part/parts or an issue that can if rectified. Seems all over the place from what I have observed. C5 auto has been bulletproof over two years but being in that world you know the lay of the land with common issues. Any experience and guidance would be appreciated. And I’m too old to learn to drive stick if this forum is anything like 5

It's basically a fluid issue, they will do a triple flush and the problem is taken care of and not all have the issue, I have a '17 and have had no issue whatsoever, I use a Range Device to keep out of the 4 cyl mode as well.

Just do a search on the A8 shudder problem and a lot of threads should appear.In addition, here is a sticky thread in the tranny issue https://www.corvetteforum.com/forums...-tracking.html
Also note that the 2014 A6 tranny has not exhibited the problems of the A8 in the 2015-2019 cars.

I don't believe it's something that necessarily requires worry considering the vast majority of owners haven't had issues with their A8 transmission and the the triple-flush process has proven successful for most cases in resolving issues for those who do.

Thank you. This is very helpful. Going with a 2014 may be a direction for me. Certainly helps to narrow things down. I’ve already dealt with trans shudder in my Camry, a DD but not a special car to me. Drove me crazy. Had I spent $60k on a car having problems at 3000 miles, I would lose my **** Since I’m going from a $15k Corvette that I never thought I’d have to a $35-40k weekend car, the thing’s gotta run right.

I think the trans thing is over blown. Sure some have problems but over all the A8 is a wicked trans. My Camaro had (since I don't own it anymore) 250 plus hard passes down the drag strip and 13,500 miles. I punished it every time I went to the track. It never had the fluid changed and its still shifting hard and fast. Not many transmissions can handle over 850 rwhp for over 200 of those passes and never fail. I have an A8 in my C7 and I'm going to keep drag racing it and adding power to punish it also, its a great trans and wouldn't think of changing to a Manual. Remember manuals and clutches fail also. Nothing perfect.

Hard to sort out the realistic picture as the only people who tend to speak up are the people who have had the problem. Have had plenty of experience and time on C5 forum to decide what is common and what is unfortunate but that is out the window here. As I’m going to likely buy a car with some mileage (25-40k) I am be able to assume that if this is a fixable rather than structural failure point, it would have popped up and been worked out or never was. Your overview helped a lot. Thanks

I wasn't, it was the OP that was/is. Perhaps you should direct your response at him not me? I stand by my recommendation.

We had the dreaded shudder on our 2016 rag top at 15K miles. Dealer did the triple flush under the power train warranty. That was 3500 miles ago and no further problems. If it were us, we would not be to concerned over the potential shudder issue.
We trudge on.
