My transmition guy said he has seen way more problems with the 6 speed than the 8 speed. My in law has a 2019 suburban with the 6 speed and it granaded afer 100k miles. I have a 2017 silverado with 6.2l and 8 speed. I flushed the transmission at 25k miles when i felt the first shuttering. As long as you catch it right away people have had good luck
New billet torque converter and new atf fluid(mobil1 synthetic lv at hp) total cost with labor $1400. It runs good now. If your mileage is high it's probably to late for that
@marekkrepa9982 thank you! I'm at 92k miles. It's probably too late for mine. It lurches when it shifts, so I think it's shot to hell. Might just pick up a used one and have my friend install it and then sell it to the dealilership who fucked my with it in the first place.
@shlomofreeman it's probably to late to save it with your mileage and symptoms. Maybe ask someone at transmission shop. Those trucks are pretty reliable if you put $2500 in it at the beginning ( because GM didn't do it right) and stay away from places like jiffy lube. I have two sierras: 2016 with 307k miles and 2017 with 167k, both runs good. About selling it try carvana or car max, they pay way better than dealer
@Deenineninenine it depends how someone drove the truck and how it was maintained. You could make another 100k or you buying ticking bomb. Price and highway miles could be a good point but it's still lottery. Probably you should stay away. Sorry, but you asked a question that nobody can answer.
Would you say the 6.2 with the 8 speed is more reliable?
This guy is nuts. He just said you need replace transmission but gives it a high rating. I have all those issue, don’t buy
what does the dealer say?
My transmission went out after 104,000 miles on my 2017 GMC Sierra 1500 6 speed.
Mines went out at 72k miles luckily my warranty covered it up to 75k miles still ridiculous though

Is this just a AI driven channel? Video was like a robot.
You sound like a computer generated voice. Are you real?
My sierra shudders like crazy when I'm driving.

I’m thinking of buying a 2017 gmc sierra sle with 200,000 miles. Should I do it or will I be breaking my bank just keeping it on the road ?
