4l60 to 4L80 Swap on a NBS Silverado

[@1ruckus1]

What was the total cost of the whole swap

[@sanjuan240]

Used trans (risky) 600$ Flex plate 130$ Torque converter bolts 15$ Cross member 165$ Trans cooler 150$ An adapter for cooler 16$ An adapter for transmission 45$ Custom driveshaft 150$ Jump harness 38$ A couple of this things you can pick up together like all the transmission things and the trans cooler isn’t needed but this is what it cost me

@@sanjuan240 thanks! How does it feel when you are driving? Do you feel a difference? What made you do the swap?

[@sanjuan240]

@@1ruckus1 I kept breaking stock 4l60 with just bolt ons. Plan on going turbo eventually and read that even stock 4l80 can take handle some decent power so figured why not.

[@1ruckus1]

@@sanjuan240 yeah mine is starting to slip so I'm trying to decide to rebuild swap or replace with but the 4l80e I find here in Tucson dudes are asking 800-1000, I might go turbo in the future to, how is the driving now dose it stay in gear longer? Are you able to break tires loose easy now?

[@sanjuan240]

@@1ruckus1 honestly bro I would buy the cheapest 4l80 you can get and have it built even a stock build would be better then nothing. 1st and 2nd are a little longer. Can still break the tires easily. You could always mess with the diff ratio so it works for you

[@joelrugg]

Good instructions

[@sanjuan240]

Thanks!!

[@LSXMILLER]

Cool info 👌

[@sanjuan240]

Thanks

[@tokitrucks]

I just pick up a a yukon with a 6.0 4l80e 2wd how hard will it be to swap it in a Silverado 2wd

[@sanjuan240]

Pretty easy i would think you literally have all the parts you need. Might just need a different/custom driveshaft I would think

[@orabates1823]

Why did you hang the TruCool upside down rather than the way the factory one is hung?

[@sanjuan240]

Just from research I found out it didn’t really matter orientation wise. It was just easier for to mount this way. I just figured if I ever take it off the mess will be minimal. Trans never got hot this way btw.

[@juan_chava4383]

Keep this silverado build going

[@sanjuan240]

Plan on it we also got my brothers truck we will be working on.

[@chrisshreffler2116]

What's your electric fan setup

[@sanjuan240]

Oem fans from the corresponding truck WITH the oem harness and relay box. Repined to stock ecu AND tuned so they operate as factory would.

[@CL-qb8xp]

I don't know if you did or not but lube up the snout on the torque converter or the pilot hole on the flex plate along with the lineup pins on the transmission case. Prevents any corrosion from forming on either the trans or torque converter in which saves them from becoming a bitch to get apart from the engine in the future.

[@sanjuan240]

Good tip I did the torque converter but didn’t do the lineup pins

[@joshkorson5991]

Freakin awesome

[@sanjuan240]

Thanks

[@MiguelSanchez-rb3tw]

Can u use the stock 4l80 flex plate? They’re cheaper than that one or does it have to be that one

[@sanjuan240]

The one I showed is a stock flex plate just different brand

[@MiguelSanchez-rb3tw]

@@sanjuan240 alright thanks bro appreciate it🙌🏼

[@leotapia7426]

What dipstick did you use and were did you get it ?

[@sanjuan240]

The 4l80 dipstick

[@Slowboymanny]

Would this be the same concept for a crew cab ? 4l60 to 4l80? 06 nbs

[@sanjuan240]

I would think so only difference I can think of would be the drive shaft length.

[@Pedritoe]

Does the truck still feel light and spunky or does she feel more lousy it’s the only thing holding me back from actually doing the swap my truck already has 4.11s so it should help it

[@sanjuan240]

It actually feel the same honestly just get a proper tune when your done

[@caesarsalad5932]

How did you go about finding the measurements for your driveshaft

[@sanjuan240]

I would go to a driveshaft shop and ask what measurements they need might be different from mine. In my case they wanted from the output shaft on the transmission to face of the yolk on the differential side

[@TerrickHarden]

If I pull my 80e from a junkyard I should be able to use the flex plate that it was attached to right? Instead of buying a new one??

[@sanjuan240]

You should yeah hopefully your grabbed all the bolts for it and and the torque converter bolts

[@adriancervantes19]

What was the length on your driveshaft you got made?

[@sanjuan240]

I don’t remember actually. I’ve read the stock 4l60 stock driveshaft length works with a new yoke but I can’t confirm.

[@Kevin_Yagoonie]

Trucks same color as mine

[@sanjuan240]

Nice!! It’s not a bad color, I don’t see it that often where i live

[@manuelmtz10]

Same color as mine, mines a ext cab. Great video!

[@Kevin_Yagoonie]

@@sanjuan240 same here.

[@generamos8745]

Did your gas mileage change?

[@sanjuan240]

I haven’t calculated it yet but I feel like it’s around the same

[@snowman6512]

are you running the starter from the 4l60?

[@sanjuan240]

Yes bolts up and lines up fine. Reason why you need the the 4l80 flex plate

Do you got a insta??
