As luck would have it my 2004 2500 HD has run its course the rear diff has began to seep from the housing the body is trashed rusted through beyond repair and the frame is not far behind

but the engine is still running great with only 140k miles. so today i began my search for a different truck and i happened to come across a 2015 Silverado 1500 with out a motor

i did not even think about the transmission i instantly started considering a swap.

So my questions are as follows:

 

1. what is all needed to throw my 6.0 lq4 in front of the newer 6l80e if it is any good yet?

2. if the trans is shot on the 2015 what is all needed for me to throw my engine and trans into it?

3.do i need to use my transfer case?

4.what about the rear end if i have to use my transmission and transfer case? 

 

i know the ECM needs to be changed if i use the 6l80e along with the cam sensor but i'm sure there's a lot more to it that i cannot find

so i am asking for every persons input and help.

please all information will be helpful and useful even if it doesn't seem like much to you it will be valued by me.

 

THANK YOU

Modern cars have what’s called a can bus system that allows all the computers and sensors to communicate with each other. It allows a lot of features, functionality and safety measures that would otherwise be impossible.

 

While it’s not impossible to LS swap a k2xx, it is so difficult that the cost and time would far far exceed any savings or benefit that can be had from the swap and you would probably be going with a custom dash with custom gauges.

You'd need a newer 6.0 like from a 2015-2019 HD.  And even then, its LS vs LT engine.  Some things might work from the 1500"s wiring, but its still gonna need some work.

As said you can't put a port fuel injector engine into a vehicle that needs a direct injected engine.

 

There is no way to make the computer function at all, it will not have a clue what to do without any of the correct sensors, direct injectors or high pressure fuel system hooked up.

 

Your only option for this truck is another Eco Tech 3 DI engine.

It could be done but would require a lot of custom work.  Which means expensive.  You are much better off getting another 2014-2019 5.3/6.2 and using that instead of the 04 6.0.  Use the 6.0 in another project vehicle or sell it.

      on-wheel cellphone control: 2026 1500 WT (2.7L 4WD std cab)

      By bwiese · Posted

      I have a basic 2026 1500 WT  (2.7L/4WD reg cab shorttbed). Comfy, generally happy with electronics/radio - but is there a way I can add switches to steering wheel right-side position (curr. empty) so I can adjust volume, push phone button to voice dial, etc? Bill W San Jose

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By Tyler Gibbs · Posted

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.

      "Life is getting back to normal."    I'm driving again and all new joints are operating as expected for this stage of recovery.   My most recent joint replacement still requires a lot of attention but experience has taught me that time will quiet the remaining pain.  I joked with my surgeon that another joint replacement would take my mind off my most recent surgery and he responded by saying the next will be a hip!  There are no plans for another surgery but, unlike me, I don't think he was joking!  I certainly wouldn't refuse further replacement  if required but hope to spend time out of the "post-op"  period.  I can't stress enough that if you have been recommended for total hip, knee or shoulder replacement that you welcome the offer.  Post-op "recovery" may sound daunting and painful, however, this is far better than the insidious erosion of mobility you are currently experiencing.  Imagine what it would feel like to wake up most mornings feeling better and more mobile than you did the previous day!  Prior to my first surgery in June 2025, even getting out of bed was becoming a formidable task.  Since the day after my first surgery, I get out of bed everyday easily and unassisted.  Making the switch to feeling a little better each day rather than a little worse, is hugely motivating!
