I have a 2016 Chevy Silverado 1500 LTZ-Z71 with 45,000 miles on it.  Dealer suggested transmission flush. I bit, but as I am leaving the dealership, employee stated since my Silverado has an 8 speed transmission instead of a 6-speed, it is a different kit, different fluid, and more fluid, so it will be $100 more than the $269.00 original quote. Has anyone heard of paying $100 more for a transmission flush because it is an 8 speed over a 6 speed? Just because it has 2 more clutches, it need different AND more fluid to the tune of $100? Thanks in advance!

Welcome to the post.

 

Yes they are different in a lot of ways, not sure about the fluid being different, but ask them to break it down for you.

How much more, and where the other costs are coming from.

Not sure on the 6sp per say but on the 8sp it is my understanding that to do a total fluid exchange it requires 20qts of fluid.

Clutch pack qty's same I believe 3qty.  The fluid is WAY pricer than Dex6 and it takes 12-13qty to replace along with cooler & TC.  So yes it will be 100.00 bucks more I usually pay 200.00 something for my service on 8speed.

Anything the dealer does you will pay a ultra premium price for so-so work.  Service departments take advantage of the fact that there's not as much mistrust of them as there is of car salesmen. The objective of OEM dealers is to see customers often and increase profits.

I just had this service done on my 2016 GMC Sierra SLT yesterday. At first I called around and got prices, 215, 300 and 467. Called the 215 back to confirm that that is the price, even for an 8 speed since the other 2 checked the VIN and he confirmed that it's a flat rate special.

 

When I checked in he says that they only need to flush it for 167. I questioned him and asked if they had the machine to bring the fluid to temp and he was oh yeah. I let it go to see how it would play out.

 

Sure enough I get called out when the tech reaches that part of the service visit and informs him that they drop the pan and change the filter and fluid, just like I tried to tell him. I authorize it and watch the head service tech tell him that the fluid is more than the normal and he says to me again it's a flat rate special and that's what I paid.

Hi I have 2017 GMC Sierra 1500 Denali, which has transmission shifting uses at low speed at about 10 mph, are you all having issues. Every time I take it in for service I have them check the trans they try something like replace the fluid and adjust clutches but nothing helps. The first couple of times within 25K miles I took it in they said they had found leaks in the trans seals but since still having the same shift issues now at 46K miles. I've been reading that there is a class action filled against GMC for this.

      Oil Consumption

      By KARNUT · Posted

      No I didn’t watch a video of a person who analyzes oil for a living explain general oil usage. For clarity I did ask my brothers one who runs our equipment business. The other who runs our old ROW business about oil usage. Nothing has changed since I retired. Their personal vehicles or work vehicles use no oil. Not enough to see on the oil checking device. Then I pondered. I like to ponder. In this extended oil changing world with oil change countdowns or lights. If engines used say a qt every 2500 miles or up to even 4000 miles. With oil changes reaching as high as 15000 miles. Normal for most people is eight to ten. Vehicles should potentially be seizing up all over the place. Especially in hilly terrain. Just how many people actually check their oil? Maybe 10 percent. Those are the people that probably change their oil early. I like to research used car listings. I have five favorite dealers I check. They all list carfax with their listing. It’s rare to see vehicles with anything but extended oil changes. Transmission service, forget about it. I’ve seen Honda and Toyota certified vehicles up to 100K miles and ten years old. With nothing but normal maintenance. Isn’t nice we all have different experiences and believe our way is the best. You certainly get backup for whatever you believe. Life would be boring otherwise.

      RUMOR / INSIDER: 2027 Silverado Dealer Reveal NEXT WEEK

      By RobbertClaus · Posted

      Interesting rumor. Dealers near me have been tight-lipped so far, but if this reveal actually happens next week, I'm really hoping they finally give the HD a proper interior overhaul. The competition has been eating their lunch in the cabin department for a while now.

      Oil Consumption

      By Chuck FB · Posted

      There are a few good takeaways in that video that pertain to this thread, certainly the possibility of the oil control rings having buildup, the fuel injectors and how clean or not that they are ending up affecting the pistons rings carbon buildup, and the fact that its normal up to a point for a given engine to use some oil, and that the oil quality that is being utilized is part of that ring clogging up issue as well.   I was talking with a neighbor yesterday who has a baby LZ0 duramax and he had bought it slightly used but it does consume some oil and he has switched over to 5W-30 Euro spec oil and in this case that never made a difference in consumption over the factory 0W-20 recommendation. He finds it uses a quart in about 3500 miles and as he goes a ways over that distance he adds oil to full and goes another 1000 miles or so and then changes oil and is typically at 40% or so left on the oil monitor at that point with his use case of quite a lot of highway miles and more limited in short run use. I don't know what other LZ0 engines are doing for oil consumption but that is what his is doing.

      Ok well I guess Lake disagrees with me on a few points. I call oil consumption pretty basic. Rudimentary. He calls it "really complicated." I think 1qt consumed in 3k miles is a lot. He says that's normal. In 22 minutes, he'll use his natural talent to explain oil consumption to anyone watching this video. He covers everything from obvious engine damage to how normally functioning healthy engines consume oil by design. Lake explicitly states how you drive will impact oil consumption.   Shut up and watch:
