Thx bro I will try it

[@MohawkMotors]

Good luck!

[@suxelcamp]

Like your work we swap 4.8 to 5.3 ls truck turns on but dont run turns off iits a 2000 chevy to 2004 chevy

[@MohawkMotors]

What did you swap?, just the engine? Engine and harness? engine, harness and computer?

[@suxelcamp]

Pulled out engine from 2000 Chevrolet with 4.8 swap it with a5.3 LS from a2004 Chevrolet took everything off the 5.3 installing everything that we took off 4.8 we left wire harness and the same computer to the 2000 Chevrolet turns on but as soon as u accelerate it it turns off

[@MohawkMotors]

OK so it sounds like you used the entire intake manifold, wire harness, and computer that is original to the truck, so it shouldn't be a vat's issue or a software compatibility issue. If it shuts off when you go to accelerate, does it shut off hard like someone turned the key off, or is it a slower shut down like it's not getting enough fuel? There's enough difference in displacement that you're going to have to get it tuned to run correctly. If it will idle until it reaches operating temperature without turning on the check engine light or anything then it's probably fine as far as wiring and sensors.

[@suxelcamp]

When u say a vat,s or software issue dont really understand

[@suxelcamp]

Yes a slower shut down like not getting enough fuel

[@breakinggames6356]

I might be getting a 4.3 from a close friend soon and I intend to swap either the 4.8 or 5.3 in since the millage is 180,000 but its pretty damn clean the only rust this truck has is on the left bed fender it just started but the cab rockerpanels and cab corners are completely solid the frame is clean I might do it

[@MohawkMotors]

Sounds like a really nice truck! Swap it!

@@MohawkMotors or maybe ill go one step further lq9 swap it and make a home made Silverado SS

[@MohawkMotors]

@@breakinggames6356 could absolutely do it, especially if you're not on a tight budget. In my area, LQ9 are substantially more expensive than an LQ4 for not that much performance gain. You can build a "poor man" LQ9 by putting some 862 or 706 heads on an LQ4 for less than you can buy an LQ9 in my area.

[@breakinggames6356]

​@@MohawkMotors ah noted the reason I was thinking of it is because the local junkyard in my town has a ton of escalades and yukon denalis which people keep telling me have the LQ9. all the other vehicles just dont match the year the ones with 4.8s and 5.3s are the 99-02 style I have the 03-05 style

[@MohawkMotors]

Yeah to my knowledge all of the escalades came with the LQ9 engine, only the 06 Denali's got the LQ9, 02 to 05 denali's had got an LQ4.

Are you sure there were no 6.0L 4L80E 1500 Silverados in 2005? Or were they just 4WD?

[@MohawkMotors]

I don't know of any regular 1500 silverado's that got a 6.0 in 2005. BUT gm did build 1500 seirra's in 2005 that IF you upgraded to the Denali trim, came from the factory with a 6.0 in them. Could also get a 6.0 in the Silverado SS which was technically a 1500 platform. I believe in 2007 gm started offering the Vortec MAX option that got you a 6.0 in a 1500 series pickup also.

[@gilbertcruz5878]

I’m haveing issues with the ac it only works when bypassed on the fuze box helppp???? Same engine swap 6.0

[@MohawkMotors]

Have you checked all the pressure sensors to make sure they are reading what the PCM wants to see?

[@user-bj5ig2gn2s]

How much need you charge for the entire job??

[@MohawkMotors]

To do a V6 to V8 conversion with a 4l80 swap also I would charge between 11 and 13 thousand depending on which V8 you wanted.

[@Humbertoponcejr]

Okay I got a question so basically where does the gray , dark blue and gray and black cable connect into the cruise control box ?

[@MohawkMotors]

You're going to have to find a wiring pinout brother. I don't know exactly where they go off the top of my head and there are slight differences in connector pinout based on the year truck.

[@Humbertoponcejr]

@@MohawkMotors okay thanks 👌🏻

[@jesseesquivel6248]

Nice video bro I did a LS swap also but I keep getting a code PO106 map sensor. I checked my wiring to plug and am getting 5V like I’m supposed to and changed map sensor and still getting this code. Can it be the tuning is off

[@MohawkMotors]

Did you check the signal wire to the pcm at the pcm connector? Could have something going on in that wire causing an out of expected range signal to the pcm. If you can, back probe that pin at the PCM with a large needle or T pin and then see what you get for voltage with the key on but engine off. Should be able to look up the signal voltage for atmospheric pressure and compare that to what you're getting.

[@SevastianNavarro]

I got a question for you man

[@MohawkMotors]

Sure, what's your question?

[@user-lt6hj8zv3r]

i been doing some research and i was wondering if i could hypothetically take the 6.0 vortec with the Hydra-Matic 4L65-E transmission from my 03 escalade into a 99-03 gmc sierra

[@MohawkMotors]

Yes you could. It will bolt in without too much issue, but if you try to put it into a 99 to 02 gmc sierra, you'll have some electronic troubles to figure out. In 2003 GM implemented the canbus communication system in the trucks and suv's that allowed all the different modules to communicate with each other with more detail, it makes it challenging to get an 03 or newer pcm to be happy and get along with the 99 to 02 vehicles.

[@user-lt6hj8zv3r]

@@MohawkMotors thanks for the reply, i couldn’t find anything other than this helpful video 👍 would it be smarter to put it in a sierra that is an a newer model than an 03 for the pcm to get along better ?

[@MohawkMotors]

The least difficult swap would be to put your 03 escalade engine and transmission into, would be an 03 to 05 sierra. The gmt 800 platform which includes 99 to 07 classic GM pickups and 99 to 06 fullsize GM suv's, are all electronically very similar from 99 to 02, 03 to 05, and 06/07 classic. There are a few late production 2005's that have a ground battery control module which can be a pain to delete or add but other 03 to 05 trucks and fullsize suvs you can swap the drivetrains around however you like.

[@AndrewLeist-q2q]

What driveshaft did you use?

[@cozart2241]

I have a 2001 single cab Silverado 4.3 & want do a 6.0 swap my questions are what year should I get the engine off of , I would like to do headers as well along with the swap will I have a service engine light due to the headers , will I have to mess with the fuel pump , I’ve heard people mention to be careful on which motor mounts we get so am I free to get any ls swap motor mounts or is there a special kind for the 6.0, will I have to mess with my break booster my truck is a v6 but came with disk breaks all around , will the v6 plumbing work on a 6.0, these are my questions thank you for the guidance with the KZbin videos & thank you in advance

[@MohawkMotors]

Going to try to answer your questions in order, The easiest 6.0 to swap in will be one from a 1999 to 2002 silverado or sierra pickup, if you can, be sure to get the engine complete with harness, accessories, and pcm. Don't cut anything, unplug all the wire connections and disconnect all the hoses. Headers aren't a problem as long as you get headers with bungs for the upstream oxygen sensors, the pcm need the information from those sensors for the engine to run correctly. The 4.3 V6 1500's and the V8 1500's use the same fuel pump, you don't need to do anything, just use the factory pump and sending unit. You can use factory motor mounts. Just get a set of motor mounts for a 2001 silverado that originally had a 5.3 engine, and the motor mount frame brackets for your year and drivetrain truck with a V8. If your truck is 2wd, you'll need the driver and passenger side frame brackets for a 2001 silverado 1500 2wd with a 4.8 or 5.3 engine. Don't need to do anything to the brake booster, all it needs is engine vacuum hooked up, it doesn't care what size engine the truck has. Same with the brakes, no modifications needed. I did another v6 to v8 conversion last year and went into a bit more detail, here's the link to that playlist kzbin.info/aero/PLW-JXcGYHUpTEVb4mJFNglNM2aCFmKptZ

[@ImNotHereToArgueFacts]

Q: Why did you need to do a segment swap? You kept the rear O2 sensors, I assume. Is the rear end different?

[@MohawkMotors]

Segment swap was necessary for the PCM to be able to control the transmission. 4L80 has different operating parameters than the 4L60. Segment swap for the engine as just the easiest way to get the correct tuning for the 6.0 engine. Can neither confirm or deny that the rear O2 sensors are are functional. Rear end is the original to the truck, didn't make any changes to it.

[@ImNotHereToArgueFacts]

@@MohawkMotors Was that a legal reply? 🤐 I thought engine/trans/ECM were originally from same truck. Maybe another swap video I watched.

[@MohawkMotors]

Engine, trans and ECM were originally from same truck, but that truck used a different operating system (OS) than this truck. So I had to use another ECM with an OS compatible with the truck, and then swap in the engine and transmission segments.

[@MohawkMotors]

The connections/wires you need are run to the cruise control module mounted to the firewall of the V6 trucks. You will need to find the wires you need in that connector, and relocate them to the c100 connector for a drive by wire v8. If you haven't already check out LT1swap.com all the pinouts and diagrams you need are there.

Why is it turning so many RPM at 70? I assume it is a 342 rear end.

Any idea if it works to use a early 2000s 5.3 and swap it into a 2010 silverado

[@MohawkMotors]

It would take a lot of electronic conversion. The 2010 silverado uses a much more elaborate electronic communication system than the early 2000's 5.3. It would be less expensive and easier, to just get a 5.3 from the same generation of truck.

[@zeppelin926]

Great series of vids. I'd like to have the same thing but with a manual. Considering most manuals are v6 would it be better to start with a v6 manual and swap to v8 or start with a 5.3 auto truck and swap to manual? I wouldnt mind the 5.3 for now.

[@MohawkMotors]

There's a few things to consider but if I were going to do it, I would start with a v6 truck with a manual and swap it to a V8. Around me it's a lot easier to find V8's to swap into a truck than it is to find all the manual parts, pedal assembly, transmission, driveshaft, etc. As far as the actual work, it would probably be a little bit less work to convert to manual, but not much.

To just swap it from 4.3 to 5.3 or 6.0 and keep the 4x4 would be pretty easy.
