DIY C8 Corvette DCT Filter Swap: Easy Steps!

- In this video I am replacing the Dual Clutch Transmission filter on my 2021 C8 Corvette.
The filter will be replaced later this Fall when I hit the 3 year mark and I will have the dealership replace the filter and transmission fluid along with a filter flush.
This is a simple DIY if you just want to change the filter and dont want the transmission flush before replacing the filter. For example, if you are well past the recommended mileage for the first DCT filter change, its not recommended to perform the transmission flush right before the DCT filter change as this may over clog the filter. This is temporary, until I have the transmission serviced by the dealer in the Fall but just wanted the peace of mind of having a new filter for the summer.

Nice camera work done on this video. HOWEVER, there is more that GM does prior to changing the transmission fluid filter. The transmission is put into a rapid recirculation mode with all solenoids open to flush debris into the old filter. I agree with you and changed my engine oil and oil filter myself prior to the 7500 mile recommended first oil change. But I will leave the transmission filter and fluid change at the intervals recommended by GM to GM, as I do not have the electronic equipment necessary to do a proper job.
The hydraulic flush isn't needed. I posted another video on this.
@@SerhansGarage It may not be “Needed”, but why not do a complete job as the transmission filter is not replaced very often?
Okay - I just watched your video regarding what the GM engineers said about the transmission fluid flush and filter change. Very interesting and thank you!
Good job! FYI, you don't need to remove plastic panel, just loosen front screws!
Thank you. I'll try that next time
Thanks I will Do that next time
I did this as well, thanks for the tip!!
Just finishing up the DCT filter replacement, so easy! Your tips were spot on! I paid about 100$ w the filter and sockets I had to buy..
Glad it helped. I have another video showing an easy method for topping up the DCT fluid and I have another video explaining the DCT hydraulic flush os not needed. My local GM dealer is charging $1, 000 CND for this easy task.
@@SerhansGarageyeah, I researched the flush and found it wasn’t necessary as well.. 👍🏽
You are correct. Do the maintenance yourself, and you will know it's done correctly.
The good thing is they use an O-ring as opposed to a gasket so it’s kinda hard that it would ever leak
Excellent video, I think taking the cap off is probably the toughest part.. I'll change mine when I get to the 7500 mark.. I have changed the oil, it's pretty easy.
Thank you. Topping off the transmission fluid was also super easy using the 'side' method as per my other video.
I was thinking once you remove aluminum panel you could use a laser cutter to cut a hole under transmission filter, this way you don't have to remove all those bolts to replace transmission filter. Engine has a hole for filter why doesn't transmission filter , design flaw
That would be handy to have a cut out..the Engineers maybe thought it wasn't needed since the DCT filter is not changed as often
Good Video, Sucks that your lower piece is missing, Ya cant trust anyone with your car,.....Looking forward to the Trans fluid video, I'm really curious how to check the existing level, and how/when to add more.
Good info
THANKS FOR THE VIDEO. 👍
My 2020 Stingray which I purchased used January of 2024 is close to 12,000km and I'm considering doing this myself.
But after reading some of the comments it sounds like you would actually suggest that at this point I should bring it to a dealership and have them do the entire flush and oil change as well.
Also if I attempt this at home I will have to manage it with reversing the car up onto a set of ramps in my garage since I don't have an actual car lift.
The ramps worked just fine for my engine oil change , but do you think they would be okay for this transmission service? . Or should I just bite the bullet and bring it back to the Alberta dealership (Competition Chevrolet Stony Plain) and have them do the entire job?
@vidman999 I think the C8 requires the DCT to be changed at 3 years regardless of mileage so if yours is close to 3 years, change the fluid and filter at Same time. It's an easy DIY but I'm planning to have the dealer do the service to safeguard future DCT warranty claims. If you are wanting to change just the filter you will have enough access by reversing onto ramps
@SerhansGarage yes I'm sure that enough time has elapsed now that it's transmission oil needs to be changed as well. And with looking at videos about jacking the car up on one side or all of the trouble that it takes to get around that air cleaner box, I'm starting to think that this is getting well beyond my DIY capabilities. I'll just have to get a grip on my paranoia and accept the fact that maybe they WILL actually do the job correctly at the dealership.🙄
Thanks for such a nice vid. One question; don’t you need to add some new fluid back to the DCT since some were leaked?
Yes you should add 2 ounces IF you have not topped up DCT fluid before. If you already topped up before (for tracking g purposes) it's not needed to top up for the lost fluid. I added 1 quart of DCT fluid - I have another video on how I topped up the DCT fluid.
Nice Video! Im going to cut an opening to access the DCT filter. Next time when u remove alum panel can you measure from center of oil filter to apex center of DCT filter? Thanks
How much trans fluid you added? 2oz? Also what trans you used?
I added 1 quart of OEM DCT fluid. I have a video on the.top.up
Great video. I would like to just change the transmission fluid on my C8. I can easily drain all fluid from drain plug on pan. Can I measure what came out and add this (new) entire amount through the fill plug under the air box. I never seen a video where more than 2 quarts are added from the top under the air box. Thank you.
@Michael-k4n2r you can but if your wanting to add fluid from the top that os alot of work as tounhave to remove carpet liner and air box. Just drain and fill from the side fill until it starts dripping out
@@SerhansGarage Thank you for the advise. I will definitely consider what you said in your reply.
It’s not an e16 it’s an Ep14 low profile torx socket I need to be making videos on this
Thank-you so much for sharing. I'll remember that for next time.
Great video
Hello I want to change the filter on the corvette but does the motore have to br cold?? Or shlead it be hot?
@Tomisur I would drive it before to warm up.the Transmission - it will help dislodge particles.
Hello, I'm operating a Corvette c8 in Korea. my C8 currently driving a 2020 year. 41,000km,
I replaced dct filter + mission oil at 30000km.
I want to replace the dct filter because it's a replacement cycle, do I need to inject additional mission oil after replacing the filter? Or do I need to inject additional oil only when driving the track?
You don't need to add additional 2 quarts of DCT fluid after replacing the filter but you should add a little bit to replace the fluid lost when you remove the filter cover, it's about 0.6 ounces.
@@SerhansGarage Thanks. I need to replace the dct filter today. It looks very easy.
I haven’t looked yet, is there a reset for the DCT filter?
No...not for the filter
You didn't appear to do the DCT "flush procedure" that is supposed to be done before changing the DCT external filter. Or did you do it but know show it? If you didn't do it, you are not meeting the required maintenance procedures to maintain your warranty...
I am aware of the flush and I decided to wait till the Fall to have the dealer do the flush when the DCT fluid is due to be replaced at 3 years, regardless of mileage which I won't reach. The flush wasn't initially required but was added by GM so I can see why some are not aware of it. The DCT maintenance requirements on the C8 is the most confusing in the auto industry in my opinion. I addressed the flush in the description of the video but here it is:

Why would you change the filter and not the oil,,
The DCT fluid isnt due to be replaced until the Fall.
So it's the E8 and E16 sockets I need to order ? Thanks!
Someone.commented that it's technically an EP socket not E, inorder to avoid rounding out the bolts.
What is the YELLOW o-ring for?
Great question...it is for the DCT fill plug located on driver side of transmission
Is there any oil under the car from the filter?
No. Maybe I was too dramatic lol. It was just a drop under the bottom of the filter, nothing on the ground.
Labor of love, for sure.
Thank you, I try my best to ake really good care of her
