My 2018 silverado transmission just went out. Just got the call. 99,000 miles on it. Was wondering,  instead of dropping 8k on putting a new one in, if I can just have them change fluid, filter, ect. They say its squealing and shifting rough. Yes ive heard squealing twice but I took it there for sputtering and hesitating.  Any advice? I just want to take it to a dealer to trade it in. Straight to dealer

It is probably the torque converter coming apart and filling the trans with debris. DO NOT do anything lest the pump loses its prime and then it's dead. Have it towed to around the corner from where you are trading it in and cross your fingers that it makes it to their lot

Uh.  No.  Not how that works.

 

Rebuild or replace.  If you want to minimize costs, get a used one and drop that in. 

 

Torque converter probably failed, took out the pump.  The 4-5-6 clutch is probably smoked as well.

Let's see if it IS how it works! 😄

When mine failed, I got 0 warning. 8 years old and about 95k miles. I was driving down a back road in Alabama on a road trip. One minute, working just fine then I tried accelerating and it began slowing down with rpm's shooting up. No abnormal noise either. I had to roll to the side of the road and wait for the tow truck.

Mine failed first with rpm flares arount 70mph.  I tried swapping fluid and it evolved to harsh rumble strips symptoms.  I barely made it to the dealer with intent to trade it in.  Polished the paint and detailed the interior. The salesman took my keys and drove it 100ft to someone in a bay , came back and was none the wiser.  They listed it on the used car lot for 2 days and then it disappeared.  I guarantee it did not survive a test drive.

This is my biggest fear about buying off a used car lot. Too many dealers just don't do the due diligence in fully inspecting before putting the vehicle up for sale. I get why the previous owner(s) traded it in and don't really hold it against the previous owner.

 

But I went through a similar thing last summer with helping my daughter trade hers in and trying to purchase a used replacement. She did provide full disclosure as hers was already in their service department because of a problem. The first choice lasted about 3 hours before her brakes completely failed while driving down expressway going to work. She was extremely lucky she didn't crash or worse, get killed. Vehicle towed back to dealer and they "bought" it back right away as there were other problems that showed up then too. The next replacement lasted only a couple days and first they agreed to fix but then ending up buying that one back because of numerous other problems that were discovered.

 

Other bad part was that both were being partially financed. And SOP is for the financing to be secured prior to vehicle ownership being assumed and driving off the lot. And each one was a different approved loan after numerous applications were submitted. Big ding on my credit because of multiple inquiries but no other issues on credit history. 

 

Funny thing is while her car was still at dealership after being traded to them, a recall came out addressing the exact problem she had. Had it been issued just a bit earlier and her notified sooner, I would not have had to go through this aggravation. Final result was her vehicle got fixed and she eventually got possession of it back and has been driving it ever since. 

 

ETA: I forgot to mention, the dealership was really good about providing a loaner car throughout all this. It was a brand new vehicle from the dealership. After the second "replacement" car was taken back, they let her use the loaner until the work was done on her original vehicle. One night at work while she was parked in her parking garage, someone clipped the front side of the loaner and took off. Since my daughter is on my car insurance, I filed a claim with my insurance. Earlier this year I got a notification from my insurance that they were not going to renew the vehicle policies. I had been with this company for 45 years. They counted this hit and run claim against me, a windshield replacement on my Silverado 3 years ago, a windshield replacement on hers around the same time and a minor accident 4 years ago by her (her fault) and an accident with me 2 years ago( my fault) . A bad string lately I admit but many, many years of no claims. And I thought windshield claims didn't count against this and the latest was a hit and run of a parked vehicle!  I guess loyalty no longer matters anymore...

    • I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons. 
    • Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.
    • Better than stock but that's like putting lipstick on a pig
    • Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks, 
    • Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
