I have a 6 inch lift and 37s on my 2014 Silverado. I was driving through some snow and mud for about 10 mins and started smelling something burning. The outside temp was 35. The smell was almost like a rubber band but I dont think it was my tires. It was mostly snow. This is not the first time after a short time off road that I have smelt this smell just dont know where it is coming from. I am planning to switch out the trans fluid and diff fluid with full synthetic just waiting for the spring. Has anyone else run into this problem. I traded a 2010 z71 4x4 for my 2014 z71 4x4 and never had this problem.

Probably the added weight making the trans work harder on the gears you have. Probably doesn't help that gm installed a thermostat on these transmissions either

You need 4.10 gears hope you have 3.42 or better 3.73 and not 3.08. You will take the load off the tranny with 4.10 or 4.56 gears and those tires.

Poor trans. You need 4.10 or 4.30 and a trucool 40K.

No 4.30 gears for these trucks. Most already have auxiliary coolers fir the trans

I thought he might like some extra get up and go with 4.30's. Aftermarket gears of course

Highway mileage will go to crap with the 4.56 gear ratio.

If he's rocking a 6inch lift with 37s I don't think mpg was to big of a concern...

As others aaid, 37s are putting way more strain on your Trans that's what's causing the high temps. I'd go 4.56 for gears. You may regret not going deep enough with the ratio, I don't think you'd regret 4.56

aren't the tranny and differential fluids already full synthetic?

Run 4 low...does the same thing as gearing when off road. I'm completely stock, and I run 4 low anytime I'm in deep enough the truck is working or towing a trailer back to the woods.

Yes they are and have been for 15 years on the 1/2 tons.

Not terribly worried about fuel I live 10 mins from work and there are 6 lights during the drive so MPGs were already shitty. My average for a work week pre lift was 12-13 after lift it's about 11-12 depending how I feel about work that day. I do plan on switching gears to mid 4s but not sure where to go and what all to get. I would love to do the work myself but I've heard its tough for someone that has never done it. My full synthetic comment I wasn't sure what fluid GM uses but I was going to swap for royal purple when I did the regear.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
