47,000 miles - should I do all or none of these???

[TahoeFL2017]

So I stopped at the dealer and got the following quotes:

Trans Flush - $199
Rear diff service - $159
Front diff service - $99
Rear diff service - $189

So we're looking at $650+ tax, but the dealer said if done before 50k miles, I will get a "credit" towards future repairs, if I do these every 30k miles, something in the neighborhood of $4,000 for the trans and $3000 towards the differential "internally lubricated parts" , ie, no seals, etc

Who thinks this is a good idea, and who thinks this a wallet flushing?

My friend is a service tech at Ford, and says fluids are good for 100k miles these days.

But I'd like to get any potential trans/differential issues out of the way, before my 5/60 warranty on the powertrain is gone - so if the fluid changes/flushes knocks anything loose, it will still be under warranty.

My concern is resale/and or reliability down the road @ 100k plus miles.

So this would be cheap-ish insurance, as I don't really do any towing, and rarely any 4wd, mostly city driving with the occasional road trip to the Keys, Jacksonville, or wherever, maybe Georgia this fall to see some friends.

So with Light Duty use, would you change out all these? Some or none?

I have a few reservations/questions about this.

1 - Is the credit good at any dealership or just that one?
2 - I think you could replace the fluids in both differentials and the transfer case for less than the cost to do one of the items. The transmission flush, might be a little premature but might be worth it as long as that also covers replacing the filter.

Some will agree and some will disagree but I would follow the maintenance schedule in the owners manual. If you decide to have it done you could buy everything online and do it yourself. It would certainly save you some money.

Why two rear differential services?

it's 159 for them to do it initially its 189 for the tech to actually clean up the mess he makes.

You ought to run a severe service schedule, fluids are cheap insurance. Your transmission has a thermostat that causes it to run at or near the same as your water temp, 195 degrees ALL the time. I had my trans fluid analyzed and it had 10K miles of life left in it at 36K miles.

Your front and rear differentials can go longer, the transfer case if you have a 4x4 takes the same fluid as your transmission, cheap insurance to drain and fill it too. We have the same transmission but mine does not have the thermostat so it runs cooler.

 

[Doubeleive]

you must mean transfer case service instead of rear diff twice?
at any rate it's good maintenance procedure, I don't care what the ford guy said if the fool wants to run it to 100k let em, I wouldn't even consider it.

 

[sealandsky]

Ditto for the change fluids and have cheap insurance. At the minimum I'd do the transmission fluid change (flush and filter). Just because the MFG states a change interval doesn't mean that changing early isn't a benefit. I'm looking at scheduling a transmission fluid change and don't quite have 15K miles on my 2019.

My bad - I meant transfer case

Yes, correct.

I think I'm going with the trans/transfer case and see if I can either do the differential myself or find a better price.

But I kinda want the dealer on the hook for warranty-ing the transmission and transfer case.

you can save money doing it yourself, I think about 1/2 of that price (roughly) is labor if you go with oem fluids

Agree. Think I am going to wait a couple months until Florida cools down, then try the differentials myself(it's hurricane/monsoon season here, and 92+ every day, not exactly the environment to be laying on the ground lol). If it's looking like a pain, then I can always hit up the dealer before 50k miles, to get the warranty/repair credit for doing it prior to 50k miles....

If you do take on the differentials, might consider investing in a small fluid hand pump. Harbor Freight sells them.

Do it in the morning at sun up or after 5, you can easily do the differentials and transfer case yourself. You can do the transmission fluid exchange yourself, we have some posts around here explaining how it's done. Dealer charges about $175 or so.

Is the transfer case running the same fluid as the trans?

I read somewhere that transmission and transfer case for the front wheels are the same fluid

Excuse my ignorance about this , it's been a while since I've wrenched on anything.....

I don't remember what the fluids are for the differentials in your K2, the transfer case takes Dexron VI. Download a copy of your owner's manual from Chevrolet.

Your transfer case takes Dexron VI just like your transmission.

Have you looked at the trans in your ‘19 yet? 10sp in my yuk has No dipstick and says no service until 100k...plus filling it would an issue with no dipstick tube....

 

[Bob2C]

Change out all your fluids out to Amsoil Signature. You will easily get 100k miles out of them. Changed all mine at 24k along with trans filter. I’ll probably get rid of the truck before it needs to be done again. I only drive about 10k a year.

What is the severe service schedule? Is a GM maintenance plan worthwhile?
