MN6.2

Very interesting thanks for that. I'd be interested.

Thanks. I had it changed when I had the truck in to be tuned. That was about 15,000 miles or so ago.

Thanks for that. The truck does currently have a trans tune (and engine tune) from a local gentleman that uses HP tuners. The truck also has AFM disabled. Maybe I will bring this up to my tuner to try and get some specifics to what he did although he is very busy right now. I'm not familiar with how these trucks are tuned at all specifically so I just let him do what's best. Like I said I love the truck and want to keep it but I'd be disappointed for sure if I spent the money for a rebuild and it still did the weird and clunky stuff. Maybe I can get a Circle D TCC first and go from there but even then it would suck if it didn't help.

Sounds good I'll look em up. thank you

Just curious if anyone has had the time/money to rebuild one of these. Truck has 125,000 miles and counting. I Love the truck. t's a 2015 max trailering package 6.2l tuned on e85 and fun to drive but as everyone knows the transmission does it's clunky weird stuff all the time although it does not have the shudder. I just don't know if rebuilding the trans and a new torque converter will actually cure the weird, clunky nature of the 8l90. Rebuild kits are out there and so are torque converter but they ain't cheap. The truck would be perfect if the transmission was smooth but I don't want to waste my money if a rebuild won't actually help it much.

Cool thanks for posting that.

Ok I understand now. Good deal I was thinking I would only be able to go stage 1 at the max. No wonder why most YouTube vids show folks with Stage 2 cams.

Cool stuff. Exactly what I want to do to mine when my extended warranty is up. I thought I read on the TSP site that your shouldn't go above their SV cam with stock converter but nice to see you have no problems. Do you have a dyno sheet you can post? I'm curious to see the torque curve. Could you also PM me the cost as well if you don't mind? Thanks

Didn't they have to change the back of the engine to accommodate the new 10 speed transmission? Doesn't seem like enough to create a knock like that but that is one major thing they changed.

Mine does it and it has 110,000 miles. Nothing to worry about. It is a little annoying but I've got used to it.

Bought my 2015 6.2 8 speed Feb. 2019 with 95,000. Now have 110,000 and change on it. Airaid MIT just installed otherwise stock. No big issues. Not really any little issues either. Tune and e85 coming soon.

Hey all quick question. I just picked up a set of GM running boards from a local guy. I have a 2015 Silverado LTZ he has a 2016 LTZ both crew cabs (he didn't like the running boards). Part numbers are 22912947 and 22912948. The issue is that The bolts that he gave me do not thread into the welded nut and the horizontal threaded hole for the front two mounting locations, the bolts are too big. I thought these were universal? Did something change between '15 and '16? I just need to know what size bolts I need so I can go to the hardware store and get some. Thanks for the help.
