2023 Corvette C8 DCT Filter after 500 miles - How Bad is it ?
HTML-код
- Опубликовано: 8 сен 2024
- At 500 Miles I always change the oil and filter on my cars.
We did a very careful break in while keeping the RPMs moving and avoiding highway driving. The more you can keep the load and rpms changing the better break in you will get. It avoids grazing the cylinders.
I wanted to change the DCT filter too and share my findings. The first service is free and paid for by GM of you take it to your Chevrolet dealer.
I do have plans to lower the car just a little more and get it more even. It's a little higher at the front than the back back.
I hope your find our videos informative and helps gives your ideas on your own car. Corvette or not.

Thanks for sharing the things you discover while doing what you do so well.😊😎👍🏽
I would like to see more about adding the two extra quarts of transmission oil. Thanks for your video.
FYI, the European oil is not formulated for catalytic convertors. I believe it has too much ash in it for our cats. Something like that.
I didn't know the C8 had a DTC filter. Not getting soaked while changing the filter looked like a challenge. Lots of good car guy stuff!
Very good video. Clear cut no bs.
Thanks
John: As usual, meticulous attention to detail. VERY curious to see what you do exhaust wise and what gains are to be had given the mid engine packaging and C8 being NA pushrod V8 Keep it up my friend 👍.
My 23 dct filter was at 3%😅 at my 7500 mile service luckily it was free and also added 2qts extra
Your mechanic used the wrong torx bits, the normal star torx does not fit right, that is why he had to cut them down, the correct ones are called six point torx plus, they are hard to come by, you have to order them from a special tool store.
Thank you for informative video.
Man the new zo6 with the flat plane crank reving to 9000k RPM just sounds so much better then the regular c8 corvette imo because you get the exotic car look and it sounds like one too
I agree 100%. However, a Z06 is very difficult to get right now.
The problem is you can only really hear the distinct sound on the Z06 at 8-9k rpm range. During normal daily driving it sounds like a normal stingray in Z mode
@@brandonlovestech454 your joking right? It sounds completely different on start ups light reving not only at 8-9k
Terrific video. Thank you
My sales rep told me to change oil at 500 miles and the first oil change is on them.
I knew there had to be an easier way to add 2 quarts. Also I was always told and have done on my new cars is to not break in a engine with synthetic oil !
I launched the TREMEC C-8 transaxle. FUCHS makes the fluid for GM-TREMEC.
There is no "break in" fluid unless they have changed it. The cost and adding another variable to the equation did not happen in my time at TREMEC.
A small filter, high debris, and the final drive gear design makes trans fluid management important for the C 8.
Don't ignore it.
That’s good to know. The small debris was my concern even though I’m pretty easy on my cars. The thought of having dealer blasting through on book rate was enough to take whatever precautions I could.
@@LHTPerformance Because TREMEC ignored the HYPOID GEAR standard set by GM they used a straight bevel final drive gear (for packaging purposes).
One tooth to one tooth contact for the final drive gear. That final drive gear material cost is staggering. Hypoid gears have 2.1-2.7 or so teeth contacts...so the load is spread out.
Not on the current design.
So, special coating and a precision break in is needed or the gear metallurgy falls apart.
KEEP the fluid clean...change the filter OFTEN. Then, you might get a long life out of the transaxle.
The trans fluid and final drive gear lube are ONE and the same. There is no engine fluid mix with this FUCHS fluid.
My "22 is due the 7,500 mile oil and filter change on the trans, dealer price $1,000.
Yeah, my dealer wanted just over 500, I did it myself, took about an hour.. pretty easy..
Took 5 seconds to switch in my 2024
Did you not do the DCT flush procedure before pulling the filter? This is what GM dealers do along with a leak test (also software initiated).
🎉
I'm going to stay with the GM oil filter. I don't like the restriction of the Mobil 1 smaller holes. Why take a chance on starvation at high rpm?
The dry sump doesn’t have a separate drain plug from the oil pan like the C7 Z51’s did?
Nope. It all comes down to a single drain point. Oil changes on the C8 are easy and performed just like any other vehicle. Only exception is oil levels are checked with the engine running and at operating temp of 175°F.
Reach out to your local Autozone the store I work at carries it in the 5 quart jugs
Thanks. We have a commercial account with Advance Auto and they couldn’t get it.
@@LHTPerformance I will get you the part number for it and maybe they can order it that way
@@2401vernon That would be awesome. Thanks.
Dang $8 a quart is cheap. Even at my local Walmart the 0w40 ESP is at least 9.50 a quart.
I took my '23 in for the first service (2400 miles) and the advisor asked if I wanted to also change the DCT filter. I said sure. What's the harm? The car has always driven fine but when I got it back from service, the car now intermittently doesn't engage in 1st gear. Not sure how to explain it but it sorta dives forward and doesn't move unless you re-engage the throttle gently then it will move forward. I immediately told the advisor when I left that it was doing this and had never done this before. They had their transmission tech look at it and he said everything is fine. It's not.
Without double checking the fluid level, there’s isn’t much to check in the outside. I can’t see how the filter would change anything. Was the software updated at the same time ?
@@LHTPerformance thanks so much for taking the time to reply. I just wonder if they forgot to use one of the o-rings or didn't push it up until it was seated? They initially said it might be that the sump where the filter sits might not have filled with fluid but it's been 2 weeks and 500 miles since. I didn't ask about the software update but they're having me take it back in 3 weeks when their transmission tech is available.
@txman951 Get a second opinion also. I can’t see a reason changing the fluid or filter would change anything. Unless the fluid level is low.
@@LHTPerformance will do thank you very much. I'll post an update when I get it. Thank you again.
@@txman951 No problem. Good luck and keep us up to date.
Did you consider the C8 Z06 when you were shopping? Is the C8 Z06 going to be on your future bucket list?
I’ve had one order since Jan 2020. They are pretty hard to get unless you pay a huge mark up.
Mobil1 sponsors their Corvette race team so Chevrolet specs Mobil1 for their customers to use. The old you scratch my back and I'll scratch yours... 😉
great video, thx
There's no such thing as "break-in" oil or oil with "break-in" fluids in it anymore and hasn't been for years. The Mobil 1 Synthetic Oil that Corvettes are filled with at the factory, is the same oil you can buy off the shelf.
Synthetic oils get darker faster cuz they keep the carbon buildup to a minimum, help clean existing carbon & sludge build up, and keep the contaminants suspended instead of letting them stick.
I believe there’s a dry film that’s added to the bores and rings during assembly, that’s kind of a break fluid to help the rings seat quicker.
Question regarding the Trans filter. I see you replaced the filter and added 2 quarts of tranny oil but, did you replace the old tranny oil or left it in after replacing the filter then just added 2 quarts?
Is it too hard to replace the trans oil altogether at once or you felt its fine and you'll do that at the recommend chevy interval at that time?
Great video. May have to find somekind of lift to do it myself.
I changed the the fluid at the same time.
@@LHTPerformance Thanks for the reply but I didn't see how you change the transmission oil did you have to take off the oil Pan? Viewed the video twice and did see that but that you only added 2 quarts of oil.
@@nickm8651 11:59 I show the drain bolt. We did drain the fluid but showed the the 2 added quarts.
@@LHTPerformancehow many quart total you put in your transmission besides the 2 quarts in the side ? And what kind of oil you used for the transmission
Why do you add two quarts of DCT fluid when only a small amount came out when you removed the filter housing cover?
In the service manual it recommends adding 2 quarts for spirited driving or track days. Some believe it helps prevent the transmission from failing.
@@LHTPerformance Ok. Thanks.
I noticed you kept saying DTC (instead of DCT) filter most of the time in the video. Did you realize you were doing that?
lol. Yes. I’m used to referring to ‘diagnostic’ Trouble Code with cars.
So do you twist the trans filter cover clockwise or counter clockwise? Or is doesnt matter?
The housing unscrews counter clockwise. The filter itself pulls out. Twist is back and forth to make it easier.
@@LHTPerformance thanks for the quick reply. Good to know. It must be a quarter turn or a little more. Just got my 2023 c8 Stingray LT3 a week ago. Hypersonic Gray metalic with the stealth package interior and badges, carbon flash Metalic mirrors and spoiler, rockers and tire flaps. The Gray metalic is an awesome color. Looks fantastic in person and the metal flake in this paint is above normal when in the sun. Great car and haven't broke it in yet. That's why I'm looking at your videos. Great information and will change out trans filter then add 2 more quarters of tran fluid to keep it cooler and change engine oil at 1,000 miles. Then eventually get on it at 2500 miles instead of 1500. Just want to make sure the engine and transmission is all seated well before doing so. Keep up the great videos. 👍
I thought the dct was filled from the top?
it is when done the right way.
All 0-40's have Dexos
. I have 0W 40 that’s not. My GM connections tells me different.
@@LHTPerformance i stand corrected. Thanks for the correction...
@@kellsAC1 No Problem. Thanks for the comment 👍🏻
Stop calling it a DTC filter, it’s a DCT filter!
I know. DTC is another thing we say a lot. ( trouble codes)
Why, oh WHY do people have to lower everything?! Just to say they did it??? Hopefully you have glass-smooth streets everywhere ....
I'd be RAISING the rear 1" if I did anything. Have to re-aim headlights then too! Stud cars, but don't drop it any more please......
You should ask Chevrolet why they lower the Z06 ….It’s way Looks better, handles better lowered. I wouldn’t ever raise it up, it will like an all terrain vehicle. C
GM and I love crazy Corvette owners. 500 mile break in oil change and dct filter change is rediculus and a waste of money. Don't get me wrong I was in the burn money club before. The reality is only 1% of C8 driver's drive their car hard enough to be considered "Extreme use" most old dudes like this guy aren't even close.
Most of my friends including myself track our cars. But, I agree.
Absolutely not a waste of money. Not don’t take my word for it. Instead check out Lake Speed Jr.’s opinion on his channel The Oil Geek. He’s a lubrication specialist and I bet he knows quite a bit more about oil and changing it as soon as you can from the factory oil. Also LHT, give Pennzoil Ultra Platinum a try, or Amsoil. Both better than Mobil 1. Also I’d take a Wix XP filter over GM and M1 filters any day.
In conjunction with changing the oil at 500, take a sample of it and send out to be analyzed, then compare to later oil drains and see what the contaminant levels are.
@@GNX157 It’s your money. Do whatever you want. Wix are terrible filters.
@@thereissomecoolstuff , oh, if you say so.
1st comment! wooo
Odd to ask in this video I know, but since the topic is breaking.... I have an Integra Type S that just hit 500 miles Haven't taken it over 5k yet. Mainly stuck between 3500-4000 thus far. How did you break your Type R in? At what mileage did you first take it to redline?
The engine doesn’t really require a break in. It’s more important to break in the clutch than anything else. I wouldn’t go crazy but taking to redline now it fine, I’d change the oil at 1000 miles either way.
@@LHTPerformance Thanks for the assist. Lots of conflicting opinion online and its nice to have a trustworthy source. Thanks!
@@onnu2001 I’m getting my information from Honda direct. The engine break in is really just the rings. The rings seat in a few miles. I’m just a little over cautious
@@LHTPerformance we love our cars and over cautious is the best way to be. Further evidence that trusting in LHT is the way to go.
@@onnu2001 Thanks . It’s always better to be cautious than regretful. It’s true, we love our cars and they take a lot of sacrifices to obtain , so many ‘RUclipsrs’ don’t really get it . Enjoy your car my friend !
