Scruff Vette

Currently at 6,016 miles. Original oil life is down to 19%. Earliest I can get the required 7,500 mile transmission service and have it covered by GM is around 7,200-7,250 according to my dealer. I was planning on getting both done on GM's dime at the same time, but now with only 19% remaining oil life I may have to bite the bullet and pay for the 1st oil change out of pocket and save the transmission service which GM will pay for for when 7,500 rolls around. What to do?

They only pay for one oil change. It is up to you to decide which one you want to apply it to. Currently you have two years to get it done. I would pay for the engine oil change and take the 7,250 appointment for the transmission filter change on their dime.

I don't quite understand your dilemma but an oil change is cheaper than DCT filter change...If you can't make it to 7k miles for your free service then pay for your oil change yourself when you hit 0% and and have the first free service before 2 years. If you have a 2023 or earlier you could have your DCT filter changed before 7K miles and try to play ignorance since GM hasn't notified owners that if the DCT filter is changed before 7k miles it must be changed again between 7-8k miles.

You'll be fine. Get the appointment scheduled and bring it in as you mentioned.

19% = 10 weeks

You'll get down to zero most likely by time. That's about 2 months before it gets to zero. I'd just run it to the mileage to get they free oil and DCT service. Your engine won't all of a sudden grenade it it's down to "zero".

RKCRLR

I agree. The time limit is very conservative to cover all ends of the envelope. Don't worry about hitting 0%, you will be fine. Just don't drive a long time after you hit 0%.

If you have good enough weather in your area over the next month, maybe take a road trip on a weekend to quickly put another 500 miles on it and have some fun while doing it. Being in a somewhat similar spot, that's my plan...soon.

MarkMeHopeful

You have about 2-1/2 months to get another 1000 miles (7500 +/- 500 miles is the requirement). Also, as long as your 2 years free service time doesn't run out you can extend the required oil change a little past 0%. Don't get the dct filter done early because you WILL need to do it again at 7500 +/- 500.

Reset the Oil Life Monitor !!

The first service is available anytime, the DCT filter change must be done between 7,000 and 8,000 miles, tell your service rep to look it up. I think I was around 18% when I got my first service.

I read somewhere that you are fine +- 1000 miles on the 7500 mile service.

jthornton

So long as you change the DCT filter and do the flush at +-500 miles of the 7500 mile service.

From the 2023 owners manual

Read it in the GM UPDATED TECH LINK BELOW...... 7500 + OR - 1000 MILES

Dealer did my trans at 5,400 miles but I have a 2020 and they only gave a year at that time to get it done.

Wait until 2 or 3% then reevaluate. Don’t overthink it.

jthornton

Gotta like their wording.
And from the same document

It really isn’t that difficult to understand and it’s not like your car will turn into a pumpkin if you go past 0% or 8000 miles.

Yep if you don't drive anywhere it's ~8% reduction/month.
You ONLY need 7500 miles +/- 500 miles to meet the requirement to have the DCT filter changed. So OP's dealers saying min 7200 miles is NOT right. At 6200 miles you only need to drive ~800 miles in two months. SMART to just make a long drive in the next several months IF needed. Can do, if when the OLM says 5% life left, the OP is not there!

Show the dealer this GM doc:
Since they don't appear to know it can be done at 7000 miles be sure they do know a FLUSH as it is required (and IMO important to get early part, clutch wear flushed.) Heck I and many had it done year 1 on GM's dime, in my case with ~3000 miles. Dealer gets reimbursed for one REGARDLESS of miles. You just have to have it done again at 7500 +/- 500 again. I had mine done at ~8000 miles year 3 when ALL DCT fluid had to be changed. All on my dime. In fact for my new E-Ray where I will have 2500 to 3000 miles year one I'll get my free engine oil and DCT filer (with flush) done. Probably be my dime year 3 as this is my 7th Vette, I don't use for log trips but is my DD!

JerryU

That TECH LINK IS NOT THE OFFICIAL GM position. Could argue it is and lose! Note it says SHOULD BE OK! In fact that doc originally quoted my forum post that stated why all DCT fluid needs to be changed at 3 years, which I speculated was due to time based additive depletion. Now it shows the DCT fluid container that states the shelf life is ONLY 3 years. Yep, fluid can have ~25% expensive additives for things like high gear pressure (some of these organic compounds can deteriorate with time.) I noted the relatively low viscosity DCT fluid is being use for Ring/Pinon gears that normally have a high viscosity read end lub. Yep can be handled with high pressure additives but some have a limited time life! Some are consumed in use.. That is what I had quoted in my Forum Post they sited. Some DCT's use separate fluids for the clutches.

THE OFFICAL GM STATEMENT IS WHAT I POSTED 7500 +/- 500. Also if DCT filter is replaced at say 6500 miles do it again at 7000 to 8000. That has been validated by GM Exes when asked. You may not think that is smart but GM's Warranty their rules! Some may think a joke BUT if the DCT fails in the 5-year warranty and you didn't follow what has been clearly communicated for 4 years could be your $20,000 bill for the replacement.

Andybump

Yup. That tech-link article is inconsistent. However, the +/-500 mile window also appears in the 2024 Owners Manual and its in the updated service procedures as well. So, I will be going with the +/- 500 miles.

Will GM deny a warranty claim if its is with 1000 miles? Who knows. I have heard in a video a GM rep who claimed to be one that actually assessed claims, and he described a process of looking for reasonable compliance generally (not specific to the DCT filter). They may or may not be picky about the DCT filter change window - but suppose it was changed at 6000, and then at 9000. It would seem unlikely that a transmission issue, should it arise at 10000 miles would have been caused by a DCT filter issue. I'm still sticking with the +/- 500 though.
