Just got done replacing the torque converter on our 17' Chevy pickup. Transmission started acting weird and I got online and found out this is a common issue with 14' -18' model years with the 6L80 transmission. Ours started acting up at 120,000 miles. If you have one of these I'd be on the look out. From what I understand if it's not taken care of it can cause serious damage to the transmission. Just an FYI for all you guys driving a rig with this transmission.

That generation of gm half tons suck, torque converters and lifters. Had to have a trans put in my wifes Ford edge awhile back, the shop that did it had that generation chevy stacked up like cord wood. They said if you put a billet torque converter in them by 60-80k they were fine, but most people wait till failure.

I took mine out and inspected the pump, gears, etc and ended just changing the torque converter. I didn't buy the billet but paid extra for an upgraded converter. She shifts smooth as silk now. Not a big fan of GM after this pickup. I've had many chevys over the years but doubt I'll buy another unless it's a 72' K2500!

They also have known issues with their AC condensers. End up cracking at the welds and need to be replaced. Generally around 100k miles. Ours went at 85ish. I think it ran me $1300 and know of 4 others that had the same issue on 2017-2018 Sierras and Yukons. The guy at the dealership said at this point he could do them in his sleep.

Hell's yeah!! Have owned a total of 5 of the 67-72s, love them and daily drove one for almost 20 years.
I have a 2008-2012 series Denali w/230,000 and keep putting money into it because every mechanic I've talked to shows me how the newer ones are a total PIA.

I've done this too. I also replaced the touch screen and the front hubs.

Checks out. Also had a transmission harness fail, torque converter woes, and all 4 magnaride shocks fail just after the warranty was up. Go figure.

Don't forget the trans thermostat sticking too. Had that happen 100 miles into a trip towing a boat. Hi temp alarm at 5:27am, back home with AAA at 2:15pm. Back on the road in another truck at 3pm. Arrived at 9pm instead of 9am.
Trans temp was reading 260 and the hot line to the radiator was room temp. $30 part replaces the thermostat with a check valve and heat tempered spring, so fluid can always pass and more flow the hotter it gets. Has worked fine so far. But I suggest doing it before it leaves you stranded.

Was yours doing the input where it changes screens? It happens, but not a game breaker. Otherwise, besides a $30 part, truck is at 135,000 miles and had been pretty trouble free. It needs struts soon, rusty NE road salt.
That’s why I traded my ‘17 last year. When it did it the first time under warranty they told me it was a bad solenoid. I ask why it might of went bad, and got the answer it just happens.
Shortly after that it happens again, but it’s out of warranty at this point. Now it’s the more expensive torque converter and transmission. Terrible design.
I was told by a good transmission shop that they have been putting torque converters in from the 2500’s. They are apparently built better and won’t fall apart. I would look into that. They said they have been doing it for years.
Yes, mine would change screens, change music stations and songs on a playlist....had a mind of its own.

2017 silverado 2500 HD, needed a new transmission at 79,000 miles.
i had my harness failed also. Was under warranty
can you tell me how you know your shocks failed
because I think I am feeling ever bump and thought it was a lot smoother ride when the truck was brand new
They were riding like shit, crawled under and took a look and they were leaking. Replaced them with Arnott’s version that come with a lifetime warranty
mine shifts like crap also
like the guy said above me. I also had my transmission harness replaced
But I here a lot about this torque converter being bad
i also feel it doesn’t have the pep it once had being brand new. I have the 6.2 liter
any idea how much it would cost to have gm repair
