Tonight we finally start the 4l80e swap in the gmc sierra. I have had issues with the 4l60e ever since I did the v8 swap. I should have know it would cause problems. In this video I show you how to remove the old 4l60e transmission in preparation for the 4l80e replacement. The 4l80e in stock form is way stronger and should do well in this truck. This process will work in other vehicles like silverado and tahoe. I will be should you how to do the 4l80e swap and the parts and tools you need to do it. I am going to be breaking it up into multiple videos to make it easier on me as I am still gathering parts. Hit the Comments and let me know what you think.......

[@jefflaney9355]

Quick note on GEN3 decat. You can turn off the cat codes like, P0420 and P0430 (and rear O2 codes) but the GEN3 PCM still commands the cat test. It commands extra fuel to check the reaction of the rear O2s. So if you remove the rear O2s the PCM goes into a cycle that it cannot answer. Some strap the O2s to the frame. I leave them in the pipe.

[@TWAMotorsports]

Interesting and thank you

[@jefflaney9355]

@@TWAMotorsports GEN4 you can actually unplug the rear sensors and get rid of them but also important to turn off "desoot mode" in that case.

[@TWAMotorsports]

Thanks for that. I will make sure that is done

[@thomasgreen1557]

Perfect timing, About to do the same thing to my 05 rcsb. Can I ask what kind of tires and size are on the red stepside. They are exactly what I been looking for? Instant subbed👍

[@TWAMotorsports]

Thank you. They are 2015 up Sierra wheels. I listed a link to tires on red truck videos. 275/40-20

[@Velly_drums]

Good to know how to do this for the future!! I’ll wait to ask questions if any till the end since this is part 1. Thanks Travis!

Hopefully it helps others.

Hey man I’m doing a header swap on my gmc what should look out for I would just wanted to know why should I look out for since you have had a lot of nbs trucks

[@TWAMotorsports]

Pretty easy install. Need it high enough to get long tubs in

[@jamesquarlesjr.7743]

great when are you doing the install

[@TWAMotorsports]

Hopefully next week

[@mattkiser9965]

Where did you buy the polished aluminum center caps without the ugly gold bowtie for the green truck? I have looked everywhere but can't find them

[@TWAMotorsports]

Came with wheels. Link in video description

[@carsondillon403]

Yo do you have a video of you installing those headers?

[@TWAMotorsports]

Kinda. Did it with the motor install videos

[@nep639]

I plan to get lq9 and use the rebuilt/goodies as well in the 4l60e that I have laying around, I don’t tow much on my single cab so I do want to get 40k cooler etc but here I am debating if I should get it with 4l80e instead…. lol

[@TWAMotorsports]

In a 2wd it is such an easy swap for a 4l80

[@anthonyvansel8675]

Is that your old white Tahoe for sale sitting on 13 hyw just south of Warrensburg

[@TWAMotorsports]

Not by me

[@Saifmohed.8]

For the swaped 6.0 hd engine, the 4l80 will fit directly and tune without needing for any extra wiring or anything else?

[@TWAMotorsports]

Not if the original motor or transmission was different

[@TheDeen83]

Ok, Denali Deen here again lol. So I've been researching the swap, and I'd like to know your thoughts on this VS just putting in a Performance Heavy Duty 4L60e build, to avoid the swap fitting process? Also, Have you any thoughts on rear diff upgrades, or even front diff HD upgrades, to better handle more power, rather than just relying solely on the tranny to handle it all? I'm asking bcuz my 4L60e is starting to go, and will go to the top of my list for repairs and I wanted to go ahead and do what I could in the process......

[@TWAMotorsports]

They are good too. I don't know about diffs though

[@bruceherrera977]

Brother do you recomend headers on a 03 silverado 5.3?

[@TWAMotorsports]

Its worth some extra power

[@fpsweet66]

Super excited for this video. Wanting to due this swap on my 2005

[@TWAMotorsports]

Hopefully I can finish it soon

[@bigb589]

Ah, the fun of owning your own lift. I just lay on the ground the hoist the trans off my chest once it's unbolted.

[@TWAMotorsports]

Been there. Done that too

[@nickking256]

What’s the measurements for the driveshaft?

[@TWAMotorsports]

Don't remember

[@CristianGarcia-dn5fm]

Can I get the link of the headers

[@TWAMotorsports]

I rhink a link is in video description

[@ImNotHereToArgueFacts]

Looks like that exhaust might have been cooking your trans fluid that close to the pan. Watching to see how you address on re-install.

[@TWAMotorsports]

No issues after getting good transmission

[@ImNotHereToArgueFacts]

@@TWAMotorsports After watching all the videos, it looks lower. Is that what drags the ground or is it the crossmember adapter?

[@TWAMotorsports]

@danblackburn2859 the part that goes under motor to frame

[@essinnocents7125]

I had to replace my rear main on my 5.3 and let me tell you it was a pain in the ass without having the right tools and transmission jack

[@TWAMotorsports]

I agree. Lift makes it easier

[@sphincterSplasher]

Why the 4l80e? Strength right. but did any of the gear ratios get changed? Why not rebuild a stronger 4l60e with better gear ratios?

[@TWAMotorsports]

Actually the 4l60e could be built for more power but the separation between gears is not as good as the 4l80

[@sphincterSplasher]

@@TWAMotorsports can't you put better gearing in the 4l60e to make it just as good? Or does separation between gears mean something else?

[@TWAMotorsports]

It will never be as strong. Money ahead to switch

[@cherry2036]

What brand headers and y pipe is that

[@TWAMotorsports]

Cheap Ebay. Speed engineering was out of stock when I put it together

[@cherry2036]

Ok thanks i kinda want the speed engineering headers

[@TWAMotorsports]

They are the best for the money

I didn’t know about taking the starter off to get the torque converter bolts n I did it with the starter on 😂it was a pain

Thank you

[@weareallamericans7358]

4l80e will always be stronger than a built 4l60e, but it's also a major power drag. Unless your 5.3 is Supercharged you'll never put out enough power to damage either if done right.

[@TWAMotorsports]

Hopefully down the road will be turbo
