What does and does not void a warranty on a new gm truck? I'm told we can turn the motor up somehow by lowering some torque thingy? Will this void it? How about a lift? Or bigger tires? Thanks!

well alot of stuff voids the GM warranty, I mean a lot. BUT I believe the "torque thingy" you are referring to is Torque managment and yes lowering the torque managment will significantly "wake up" the Motor. although the only way to remove/lower the torque managment is a tune, and that does void your warrantly IF THE DEALERSHIP FINDS OUT. Now i refuse to start a "Dealer detectability" or Tech 2 war here but from my experience a good PCM tune is indetectable by the dealer. Not a Hypertech or any of those handhelds.

 

Onto the lift question, a lift will not in my understanding void your warranty, but it all depends on how the lift is attached to the trucks, if the lift is one of the cut and weld lifts than it might cause a problem, if it is a bolt on than it shouldn't cause a problem.

 

Tires should never void your warranty unless you stick 45's on a half ton and snap axles and rearends but that is a whole other issue. so no

 

I hope i have been of help

They will argue that larger tires void parts of your warranty. Had them argue it on my tranny, diff, power steering, and everything else that went wrong with my truck. I only had 285/75R16 on it too.

Alot of this is avoided with a good dealer. When you buy the truck, go meet with the service manager and question him about warranty. Aftermarket stuff only voids warranty if they can prove that the part caused the problem. I have bought 3 new GM trucks so far in my life(I'm 27) and none of them have had a problem that didn't end up being a Technical Service Bulletin or recall.

This info might also be helpful -

 

Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302©) . For best results, consider working with performance-oriented dealerships with a proven history of working with customers. If your vehicle manufacturer fails to honor emission/warranty claims, contact EPA at (202) 260-2080 or www.epa.gov. If federal warranty protection is denied, contact the FTC at (202) 326-3128 or www.ftc.gov. For additional information, check out the following links:

I've sound that some dealers don't mind aftermarket parts while others try to give you a hard time about the small things. The info above tells it like it is through.

      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.
