Your cam towers WILL leak. Toyota has never address the issue. Good luck with piston slap too.

Well I just got my truck back yesterday after they installed the new motor mounts.... And its gone. No more vibrations when at a stop. I'll keep an eye on it for sure (and mileage) but for now its butter.

Haha those Tundra EPA numbers are sickeningly optimistic. Go look at websites like fuelly yourself. Tundra 5.7's average low teens unless you granny them

 

As far as rough idles, clinks, or transmission consfusion... I have have ZERO issues with rough idle, shift clunks were rare in the first 5k miles and non-existent after that. With a simple tune, my 6-speed shifts flawlessly, better than most guys can row their own gears. The 6L80 is a better transmission with better serviceability and aftermarket support than that trash Aisin 6 speed Toyota went with. You'll find out when it starts slipping in a few years. It's more common than 'yota guys like to admit. Why are you still here again? Bon voyage.

I've got a 2016 tundra and easily get 16mpg. 5.7 w/ 4.30 rear end. Great truck.

So I am the OP of this thread and have been dealing with the rough idle. However, I was having 1st to 2nd hard shifts so I took the truck in and they told me there was a reflash for the trans. So far the rough idle has improved not fully away but significantly improved.

One step in the right direction, how would you best describe the rough idle at this point and how many miles at this point?

Anyone tried this yet?

The air filter housing part of it

I had the redesigned motor mounts put in my truck and it didn't change anything. Still have rough idle/shaking when stopped.

Ask dealer about the torque converter bulletin!

 

Good luck

I have a 2015 Silverado and my friend has a 2014 Sierra. We both have this weird almost stall out feeling idle on our trucks. Everything Ive read just says its normal in 5.3 engines. We can't accept that answer on 40,000 dollar trucks.

Is the dealer aware of it?

Little rant: My first new truck was a 1984 Chevy crew cab dually, biggest piece of shit I ever had, had to fix everything myself. Well keep it till 2002 and bought a 2002 7.3 F-350 crew cab dually best truck I ever had and still have it 220,000 miles and going strong. So bought a 2016 Chevy Silverado truck for my son and one guy at the shop got one. Well son's has been back 2 times for check engine light code 442, (17,000miles now) first time could not find leak and just put grease on fuel cap and worked for awhile. Second time today put new filler tube and fuel cap on. Had them check for engine shake as only our truck dose it not the other one, can't really feel it but you look at engine with hood up and you can see it. I should have told them if they were going to do the washer deal not to but they did it before I could say no and said this is what they are told to do. The service writer was cool and did not deny anything and said everything here that I have read is true some do it some doesn’t and there is no real fix. Well I will check it out when it gets home; also have a belt / pulley wine from engine. I will tell you now we will never buy a Chevy again and we need two new cars in our family now and I will need a new truck soon

Only fix is to raise the idle with a tuner, GM just put the idle down too low for emissions.

 

 

Here is the Idle table in the ECU for the 5.3L
