Fleet Truck Differences

Alright guys I have a few questions that have been bugging me. My '04 GMC Sierra 2500 RCLB 6.0 is a fleet

Truck. I want to know if there are any differences in the emissions controls on it than a dealership

Bought pick-up. I saw on a post a while back how to see what gears I have, I checked the dash code

And it doesn't have one, bases on when I typed the tire sizes in the computer and speeds and rpms

It told me I had 3.73's. I thought only 4.10's came on the 2500 though for 2004. I have 265/75/16

Tires and at 45mph I'm around 1600 -1700 in overdrive and at 65 I'm at 2,300-2,400 in overdrive.

Any and all help would be much appreciated.

Fleet and retail trucks are or for the most part the same trucks. There are a few SEOs that having a fleet number allows me to order, but I do not ever remember seeing any SEOs that pertained to powertrain options. About the only SEO I use is the power window/locks and mirrors on WTs. Most SEOs that are availble to fleet are just like special paint, or badging deletes, that sort of thing. Really nothing that has much effect on powertrains. All the vehichles I buy come from a dealer. More often then not they are right off the lot.

check your glove box for the gu6 gu4 or anything with gu...thats the gears...then type it into the rpo look up on this site...all those codes on that sticker are the equipment that came on the truck....as far as differences between fleet and dealer they should be almost the same, emission standards are set by the goverment a fleet can't change that unless its from a different country...

04 was the last year for the LD 2500s they were avail. with 3:73 or 4:10s.

If you have a LD model you may indeed have 3:73s.

 

2500s had 245s from the factory and no difference in the emissions either

except for Cali or the NE states vehicles.

 

 

Like JRO posts..............Check your RPO sheet for the GU code.

      No 12v outlets in 2026 gmc Sierra

      By PhilB · Posted

      It is possible to add your own 12v outlet to your truck.  Check out this video:   I verified via GM Upfitters that pin 31 is the same on the 1500 trucks.  The wire is GM part number 84779405.   You can get the GM 12v outlet from Amazon  https://www.amazon.com/Genuine-Accessory-Receptacle-25774623-13549530/dp/B0F1H9YRGF EWAY 12 Volt Power Adapter for GM   https://www.amazon.com/EWAY-Chevrolet-Silverado-Cigarette-Ignition/dp/B0915RRW6Q/ref=sr_1_1?   I just haven't figured out a good place to put the 12v outlet in my truck.   Some people are getting USB-C to 12V adapters  https://www.amazon.com/WYMECT-Cigarette-Lighter-Socket-Adapter/dp/B0F87WNQKB/ref=sr_1_1_sspa? Not sure if they provide the correct amperage that a device like a tire inflator would need.

      Wiring Help, Please

      Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.

      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.

      Different requirements for oil filters?

      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. 😉
