I put it in 2wd and put encoder back on. Lights just flash on dash and then 4 low light stays on even though it's not in 4low. Obviously will not shift does nothing. And yes encoder still clicking even with truck off.

did you try the modes with the encoder removed from the tc? it may be out of phase or just a defective part

That's what I was thinking also. I have also heard you are not supposed to run the encoder when it's not installed on the tc. I didn't put this one on so I am thinking I will try a different one.

did you have a chance to check it for tc codes? its a pretty simple system but it may shed some light on the problem

In my generation truck, you can't just plop in new encoder motors without calibrating them, you have to use a Tech-2.  What does your shop manual say?

      Looking at 2022.5+ Silverado/Sierra 1500 (5.3L) - Lifter/DFM Question

      By asilverblazer · Posted

      You should be evaluating enough comparable trucks to know if one sounds different than the others - if you can't tell something is amiss by ear, it's probably fine.   Further evaluate enough trucks so that you can determine what 'normal' looks, sounds and feels like. Even if this is the first truck you're looking at and want to buy, go look at several more (regardless of whether you intend to buy them).   Insist on taking the vehicle to be evaluated, spend some time looking ALL OVER IT, look for overspray where it shouldn't be, paint damaged on bolt heads that are not normally removed. Check for rust, missing fasteners, non-factory style fasteners, suspiciously new parts especially on non-wear items. Check for leaks, check fluid conditions and level (dirty isn't the worst thing in the world but exceptionally low is).   Ignore tire shine and plastic dressing that makes an engine 'shiny'.    Beware of heavily fragranced interiors to mask odd odors that could hide potential mold from a leaky rear window.   Carfax is barely worth the paper it printed on. DO NOT trust it, a vehicle can be wrecked, fixed by a bunch of drunk hillbillies in their cousin's backyard and still have a clean Carfax. I can meticulously maintain my vehicle at home with top quality parts, materials and methods, the Carfax won't show a thing.   Taking it to a shop to have a teenager working afterschool (an inexperienced mechanic) evaluate it is a waste of time.   Lastly, a good, well taken care of truck will present itself as such, it would be generally comparable to a new truck. An uncared-for truck will show it, dents, scratches, seat stains, paint swirls, tears, scuffs, marks, rattles, vibrations, clunks, miss matched tires, etc...

      If you suspect an engine swap or similar modification to the front accessory drive...   Maybe try spending some time plugging in different make/models/years that utilized the same engine (prime donor vehicles or swap candidates), vans, full-size cars (Impala, Roadmaster), 4x4 trucks to get a collection of pump and brackets that are similar along with their associated part numbers; take that collection of part numbers to the parts store to compare.   Another Okie.

      Lower trims ( WT, Custom, Silverado ( aka LT )

      By newdude · Posted

      There are knowns and unknowns.   Knowns:   - LT, RST and LTZ names/trims are gone.  The new "Silverado" trim level replaces all 3 of those.  You should be able to configure the Silverado trim to match the equipment levels of those three trims.    Unknowns:    - Custom.  No mention of what engines it will have access to.  Dual exhaust being standard does seem to confirm a V8 option for the Custom trim though.  My "guess" is that Custom will have access to the Turbomax and the 5.7.  I could be wrong though.  The current Custom trim went 2.7 Turbomax only the last 4-5 years, and only had a single side exit exhaust.     - 40-20-40.  I would imagine that is NOT going away.  They only focused on showing the new interior on the top trims, Trail Boss, ZR2 and High Country, hence the images shown are just bucket trucks up front.         The info should start coming fairly quickly over the next weeks and months.  Production is supposed to start up later this year, so when the order guide launches, you'll be able to see the configurations of engines, cabs, seating, etc.

      Brand new to this forum. Questions about re-gearing my 26’ HD

      I don’t do offloading other than a dirt road literally for me it’s more about the look which I really appreciate a nice looking truck and I like sitting a higher and not just because I’m 5 foot seven lol..  I’m also not compensating for anything lol..  but I truly think it’s safer on the road the higher you sit you have better visibility generally speaking especially a few of your Sideview mirrors adjusted correctly. They do make a programmer rough country does they’re $1000 for these new 2500s but when I do a gear swap that would be a moot point. A lot of the shops that I go to in my area they’re all saying the same thing that Yukon Detroit axle Eaton Spicer Richmond they don’t have gear shot for these trucks which surprises me because hasn’t this body style been out since 2020? I’m hoping soon they have something because yeah I’ll have to spend the 3K to get both axles done. Thank you for all of your response responses. I apologize if there’s any grammatical error errors as I’m doing speech to text on my iPhone without proofreading
