I’m gonna get on that this week. Hoping a good cleaning will do it, seeing as it does have 160K it may be oil residue or something. No noise or rattle when you get under and hit it. As for whatever killed them is another question. Oil burning maybe? It doesn’t burn a ton but like I said 160K...

That’s what I was saying. And as much as a 5% change in O2 flow can set it off. I used to have a tune and it didn’t seem to help much. The slight increase in power was nice but tranny still sucked. Went back to stock

Idk man I had to put in a reman at 150K. I drive a tow truck for a living and have towed lots with blown trannys. When they are nice and brand new they are awesome but I’ve driven a ton of higher mile 14-15s that hard shift like mine

That’s what everyone who has one says. I drive a tow truck for a living and I’ve towed tons of these with blown trannys.

Not salvage. Original owner was for commercial use, and racked up lots of miles fast, but it’s a fully loaded every option (for an LT) crew cab truck, so I doubt it was worked super hard, might have been a foreman’s truck or something. Best part, origionallt from FL. Spotless underneath

The shop that installed the reman unit told me they would flash it stock. The reman company seemed pretty reputable but the shop that installed turned out not to be lol

I had a tune for a bit and it didn’t help and honestly I didn’t like it. Ended up going back to stock after about 2K miles

I thought the same man but I did my research and that code can be tripped by as little as a 5% change in the O2 sensor reading. Not sure why but over the winter the code went away on its own multiple times. And if cleared would take days or weeks to come back. Leading me to believe it’s not clogged very bad so I didn’t think that was my issue. If you think it is my issue is there a way to check? Or a way to replace cat without spending crazy money on a truck with 160K, lol when I get under it and hit the cat it’s normal, no rattle or indication the insides have come apart.

6 speed trans (5.3L) on my 14 Silverado shifts like crap. Hard downshifts constantly random thumps even when driving and not shifting, just overall bad performance. Weird thing is I had a remanufactured trans put in the truck a couple months back. It shifted like crap before the swap but worse. New trans is an improvement but still sucks. Engine runs fine except code for bank 2 cat below efficiency. But if I clear that it takes a few days to come back so I doubt the cats clogged that bad. I doubt that’s causing my trans issues. Other Chevy owners I talk to say “that’s just how the 6 speed is” but I’d say mine is definitely worse than average. when I’m driving and engine is at lower rpms it almost feels like it’s stumbling a bit. Kind of like if you were in a manual car and shifted up too soon and started bogging down the engine. Rpms look normal tho. anyone have any advice on what to check out? I love everything about this truck except the awful shifting if I can’t figure it out soon I’m honestly just gonna sell it which sucks.

Well guys just got a check engine light P0430 for the right side cat, I’m guessing based on the code that it’s clogged and needs replacing. doesnt effect drive ability at all but I need to pass inspection of course lol anyone done this job before? I had a buddy of mine tell me the y pipe needs to be welded together? If that’s true I’m gonna have to have a shop do it cuz I don’t have a welder. I would rather not if I don’t have to lol Anyone know the cheapest way to fix this? Rockauto only sells both cats together for about $430. Anyone find them cheaper? I only need the right side I plan to sell the truck soon. any advice is appreciated
