I have a 2022 c8 corvette that I put an afe cai on. I went to a track day and now the trans is slipping. It’s a known issue so should I remove the intake to send it in. If it was simple I would but being a hard top conv it’s a pain in the ass to swap out.

I’ve sent stuff in modded and it’s always a fight but I don’t think this one is really my problem. I just don’t feel like going down the rabbit hole but I also don’t feel like hours of removing and installing the cai.

I would return it to dead stock.

No modifications are allowed by the manufacturer unless they are sold by that manufacturer even then I would make it stock for a high-dollar repair like a transmission.

I don't know what kind of data they can get from the computer that would show your driving habits ?

Good luck

As said above, return it stock. If there is a mod done before the cats the dealer will use it against you.

@jetboatperformance to the courtesy phone...

I've only been doing warranty inspections for a couple months. Most the 3rd party providers want pics of engine bay and notes of any mods. I've talked to a few dealership guys, because I'm a car dork and am curious about the stuff. The Ford and Chevy service writers I've spoken with said it's up to the individual dealership if they want to take it. The Dodge guy said "nope".

So, I think I'd go with "return to stock". One thing I've learned in doing this stuff is , "my God, new stuff is expensive!"

Yeah return it to stock or be prepared for the consequences if under warranty.

What about the Magnuson–Moss Warranty Act?

I mean they’re going to have to really prove the CAI caused the transmission to slip.
It comes down to who has more money to prove what.

It's common knowledge that an aftermarket CAI doesn't really do shit, although the manufacturers claim they do....if it did, within the realm of emmision compliance...GM would have put that on it from the factory.

Anything that could theoretically add any power can most certainly contribute to a transmission failure, and GM has a lot more resources to fight that angle than the car owner does to fight against ...I would assume.

Leave it stock until it's outta warranty, if you ever plan on using the warranty, or put it back to stock before taking it in and remove any evidence of the aftermarket parts being there.

After many years of working for gm stores I have personally verified that a k&n air filter caused second gear failure in 700r4 trans. A bulletin from gm came out soon after blaming an “overly oiled aftermarket air filter” caused a change in mass air flow readings that has direct input to trans line pressure. My guess is that later ecm data can report the mag reading low and tattletale

^This is the safest bet. It may be a pain to put the stocker back on, but less painful than a new tranny would be.

In the early 2000's, we had a communal 7.3 exhaust system. It was for whoever in the group was having to get a fixit ticket handled or warranty work. Those trucks weren't very "smart", so swapping out idm's was common too.

They can tell when you wipe your ass with the data available from the computers. I took mine in for service and I was surprised and how much information they had.

I fight with dealers all the time about my 16 Yukon XL. It was originally purchased by the original owner and the dealer he bought it from put a GM CAI and cat-back Borla exhaust on it.

That dealer has since gone out of business so they can’t be called to tell the other dealers they did it.

Dealers complain about the cai all the time as aftermarket. I’ve had to show them pictures showing it was a GM part sold by dealers at the time of my vehicle being originally sold. One asshole dealer oiled the dry filter because they thought it was a K&N (filter wasn’t even orange, it was green). I had to replace it.

Then dealers blame the aftermarket light bulbs I have on my vehicle for stuff. If GM headlights didn’t suck people wouldn’t be trying to improve them.

Finally I had a dealer blame the car alarm on my car for it not starting and they told me to take it back to the alarm place and have them remove it. I had to show that dealer the original window sticker showing the alarm was factory.

Dealers are fucking stupid, lazy assholes that want to blame all your car issues on non factory parts.

My car can’t even tell me when a lightbulb burns out, I doubt having non GM lightbulbs is something my vehicle could even figure out was there. I also doubt GM would allow GM optional kits to be installed by dealers if it was going to potentially cause problems later.

I have run dealership service departments for Ford,Chevrolet and Toyota for 30-40 years, it's not usually the dealership but the manufactures that makes the determination as quite often on larger repairs they will send a technical rep out to inspect and and say yes or no, now with money being tight they are looking for no more than yes. Return to factory stock and go for it. If you are a regular service customer the dealership will more than likely go to bat for you

💯

And just because the dealership installed something, doesn't make it manufacturer approved.

I once had a complaint on a new Chevy pickup where the owner installed a CARB legal Whipple and kept getting an MIL ( I forget what for). The dealer tried to correct it three times under warranty. Finally to prove it wasn’t a factory defect the shop foreman disconnected the Whipple computer and told the customer to drive it like that to see if the light came on. Two weeks later, the engine was toast. One piston was not round on top anymore from detonation. Guess who bought the new engine?

I am assuming the dealer payed for that one. Wow for the shop foreman to do that and not know the repercussions, he would not be the shop foreman no more.

The short answer is Yes put back to oem specs , any modifications could adversely effect a claim and dealer service advisor as well as inspectors are require to note and record any and all mods . An engine or exhaust modification for example might not effect a claim for AC problems but the warranty record will show it going forward EDIT additionally in some cases your coverage could be cancelled altogether . Some companies will even go so far as to dump the OBC and look at data that can tell when certain "events" took place such as installation and removal of programming (tuners)

Put it back to stock.

The few hours of labor will save you many hours of arguing down the road . . . and if the vehicle has continued issues later, you don't want them pointing back to the service records showing it had been modified from the get-go.

The Magnuson-Moss act protects you under some circumstances, but like anything legal - it comes down to spending money to defend yourself or plead your case if the MFG feels they have a smoking gun. Not worth the risk .. .

This, there's no way a trans on a C8 gets replaced without factory approval. Big tickets always need approval ahead of the repair, put it back to stock and hope there's no evidence of it being modified. The dealership wants the approval as it pays well, but they won't cover for you as they could get charged back on the repair.
