Justin, I'm still a little confused. I picked up my Z06/Z07 on 23Oct2023.....so is my 1st service before the 2 yrs mark (23Oct2025) or is 1st service between 7500 and 8000 miles...I only have 3500 miles as I write this to you. .....I did do an oil change in Aug 2024.....I have one more question? I saw that Brandon Garage cut an access hole where the transmission drain plug and filter is, but he put a door panel that open and close with a screw driver. Is that something that you might do? I'm thinking about just cutting out an access hole like the oil filter and oil drain plug have. What Say You. Please write back.
Technically first service is to be done before 8,000 miles BUT I wouldn't wait that long personally. I would do the first oil change and trans filter change around 2k miles and then again at 8k just to maintain GM's warranty. I will be adding that door to my car eventually when the weather warms up!
C8 Corvette has been out for 5 years and still owners are confused on the tranmission service you would hope that the salesperson would explain this in detail before leaving the lot and the responsibility also falls on the owners for not reading their owners manual.
@HorsePowerObsessed didn't know that about the manual thanks for clearing that up and your correct about the sales personnel most know little about the product they sell there are a few that are exceptional at what they do.
The flush confusion is GM's fault: 1) Most people think of a tranny flush as something totally different. Should have called it "Filter flow procedure" or some crap. Not a FLUSH. 2) The actual tech procedures for replacing the DCT cannister filter literally start with performing the flush procedure, so this made everyone freak out because: a) some dealers were saying there was no flush procedure (when there was, and its in the service manual!) b) some were charging extra for this (dealer scum) c) some people were speculating that DCT's were failing because filters were replaced, but flush procedure wasn't followed because of A above. d) P-car owners like to troll the corvette forums and spread FUD because its fun I saw a while back where the GM engineers stated this procedure is normally occuring while driving the car periodically when conditions are correct, so it's really a moot issue at this point.
Unfortunately, not everyone knows that this procedure occurs normally when driving. In fact, I'd say 90%+ don't know that. That's the biggest reason I made this video because it is ALL over the forums and people are SURE of the fact that you lose your warranty if you don't do the flush procedure first but as we stated here, that is incorrect.
What does actually the 3 year DTC maintenance consist of? I have heard that you supposed to replace the internal filter inside the transmission also, any comments on this?
I have not seen anything saying that the internal filter should be changed unless the transmission is heavily compromised, meaning you shredded some gears or something. All of the literature from GM states that that is a lifetime filter.
Thank you very much for your help and information, I own a 2022 sting Ray which just run out of warranty in December for the 3 years, unfortunately I live in a town in Wyoming where I don’t trust the mechanics that work in the chevy dealership, so I have to make an appointment in another city where they have more experience on this cars, but because of the weather I had to cancel my appointment, but as soon as I can I will get it done, but they told me that they need to replace the internal filter also and is going to cost me $1400 for the service, what do you think about this? Thank you so much
How would you know if the car was serviced correctly if you bought it used and it has over 7000 miles on it. And if it’s under 7000 do you still get the free service?
GM will have a record of whether or not that maintenance was done on that Vin. If it wasn’t done and you’re within that three-year period then yes you’d still be covered for free.
@@HorsePowerObsessed if the car had over 8000 miles on it And you can’t verify it or it wasn’t done, should you stay away from it Because GM won’t warrantee it?
Hi does this apply also on a C7 Corvette Grand Sport? I have the automatic 2019 model with 16 000 km, when do I need to change the transmission oil and filter? Thanks ! Anyone who has the info, please reply back.
You can literally do ALL of the maintenance yourself on the C8 Corvette transmission without any special tools. NO FLUSH is necessary! 👍👍
The DCT cannister cover has very low torque spec screws. Inch pounds... beware!
I chose to do it at the dealer because I want a proven paper trail.
This is GREAT news! Good information! Thanks HPO for the video!
Thanks for watching!
That thing is clean in black ❤
Thank you!
It’s clean in all colors
Thanks Justin for a informative video
You're quite welcome.
Just rolled over 7k miles. Probably going to put 200-300 more miles and I’m going in for my first oil change. Thanks for the info
You’re very welcome!
Many thanks, super update.
Thank YOU!
Great info. Thanks HPO
Any time!
Excellent video with lucid instructions. Love the driving around Western Pa surroundings. Your C8 looks amazing. 🇺🇸
Thank you!!
Chuck, the Technician with Rick Conte said late 2023 onwards GM made the transmission case larger to hold more fluid. This is what I heard.
The z06 and late 2023s don’t need the extra 2 quarts anymore because of a case redesign but it does not hold more fluid.
Always Good to know this information.. Thank you 🙏...
You’re very welcome!
Please Correct me if I am wrong, the transmission fluid is not free.. They do not pay for the 8+ quarts of DCT transmission fluid..
Correct. You will pay for that.

My pleasure!

The manual doesn't disclose everything we talked about here today and unfortunately, the salesman often have no better idea than the buyer.
@HorsePowerObsessed didn't know that about the manual thanks for clearing that up and your correct about the sales personnel most know little about the product they sell there are a few that are exceptional at what they do.
Agreed! I wish there were more!!

The three-year maintenance is an oil change, oil filter change, and transmission filter change.

The Trans is about $16.000 GM Cost good Luck!!!!
Why good luck? This is everything you need to know on how to avoid that lol
Are you going to consider the ERay?
No. The Z06 is the superior car in my opinion... With that said... A ZR1 might be on the horizon!
I might buy a c8 zr1
I might, too!

This is not the same for the C7.
@HorsePowerObsessed I see okay. Any clue for the C7 when I need to change the filter and fluid for the transmission?
Why am I seeing two wings on your Z06? @04:37 mim.
2 wings? What do you mean?
@HorsePowerObsessed @04:37 min. Looks like a low wing & you're high wing.
2!!🔥
1st!! 🔥
Coll
🤘😎🤘
Good stuff Justin keeping the community well informed, allowing DYI folks like us to save and avoid dealership fees on simple oil changes.
Heck yeah!! we spend enough money on the cars so let’s save money on the maintenance!!
Hey justin have you seen a cel for p1408? Egr code
I haven't, are you getting this code?
@@HorsePowerObsessed yeah got it after a restart
