4l80e Swap Guide for 4th Gen Fbody featuring Vasko Speed!

[@AMartin92GVR4]

Just finished my 80e swap up in a gravel driveway, and with someone who has never messed with an Fbody let alone anything LS, this swap was very straight forward and it all plugs together like legos. This video and LS1Tech will be your best friend.

Oof gravel sucks to work on, been there, I feel your pain! Thanks for watching!! What stall did you end up going with?

Did u have to get another pcm ecu for the 4l80e

[@wilsongarage9888]

Yeeeeessss turbo time baby. You already have the turbo might as well have the best in the game build a turbo kit.

[@Autofaze]

That's right! The old raffle winning turbo! Brad with Vasko Speed is a fabrication magician! Honored to get a kit custom made by him 🤘

[@felipemonreal4543]

You can use a stock torque arm with the umi torque arm relocator

[@Autofaze]

Hey Felipe! I forgot they made those kits. Yes you can, you'll need their 4l80e relocation kit which I'll put below. www.umiperformance.com/home/product/1998-2002-gm-f-body-torque-arm-relocation-kit-4l80e/

[@JoshuaGrooms83]

I'm going this route with my umi long torque arm to the umi 4l80e support with mount

[@johnsimmons8456]

Not a cheap swap… Need a new driveshaft and yoke 4L80E Crossmember Converter SFI flexplate (if racing) Trans cooler: I like Tru Cool 40k OC-4739-1 Cooler fitting adapters to 6AN male Banjo fittings for oil cooler lines Trans cooler 6AN line kit External Wiring harness - (make your own) Dipstick tube - Use Madman MM-DT 4L80E 4L80E segment swap Depending on converter, may need Crank spacer, Pilot adapter, longer flex plate bolts… I’d run a pressure sensor in the pressure port also to log trans pressure…it adds up quick but lockup and OD is so worth it over the TH400

[@Autofaze]

SPOILER ALERT haha! It is a very expensive swap but gets rid of the garbage 60e and lets you retain overdrive! The plug and play harness we used was pretty seamless and needed no segment swap. The Tru Cool 40k is a beast of a cooler, running it on multiple vehicles. We also used the madman dipstick, it is like you are naming everything in the video! Thanks John for watching (if you did lol)!

[@joe2guns]

Nice work guys im helping the transmission shop with there first 60 to 80 swap so looking forward to it.

[@Autofaze]

Thanks Joe! Appreciate you watching

[@josemarquez7731]

What spacer did you use with the flex plate

[@Autofaze]

Did not need one with the circle d tq converter. Thanks for watching Jose!

[@guysmiles2822]

Thanks for the video. Was wondering what you did for transmission cooling? Did you use the radiator or bypass it and install a external cooler?

[@Autofaze]

Trucool 40k, we did a stand up radiator for the turbo setup so it's just on the cooler 👍. Thanks for watching Guy!

[@Slowmo896]

Thought this was from stick to 4l80e at first..as that’s my need as this point..

[@Autofaze]

It is not sorry!

[@cariodelgado742]

Nice video guys.i have El Camino with 700r and I want to change to 4l80e what kit I need to make that happen

[@Autofaze]

Thanks for watching! Depends on your engine and ecu setup

[@brycegarrison2028]

I also have a Holley system on mine so would I still need to buy that wiring harness?

[@Autofaze]

Holley makes their own 4l80e harness!

[@tavarismickens927]

Hey I had question and wonder could u guys help me? I have a 98 trans am and did the 4l80 swap , I have the 99-02 ECU upgrade with 4l80 segment swap and had my original harness repinned for that newer computer and trans but after installation I’m still gettin in limp mode? And pcu tuned correctly and harness wired correctly and getting 12v, I can’t figure out what else it could be

[@Autofaze]

Im not sure tbh, kc maxx, our tuner has us get that pcm of nc 80e to 60e harness. It doesn't do a segment swap, one modified the 60e shift tables based on the instructions. The ws6 drives flawless. I've heard of guys having those issue with segment swaps but don't have any experience with doing one that way. www.pcmofnc.com/product/pcm-of-nc-4l60-70-to-4l80-conversion-harness/

[@butchjones615]

Did the stock drive shaft work with the 4l80/th400 slip yoke installed

[@Autofaze]

It does not sadly. Thanks for watching

[@shawng7902]

Those jumper harnesses arent super expensive in the grand scheme. If someone smart was to make a decent 60 to 80 harness about 12 inches long with a super low profile 90 on 1 end and car plug on other end, I bet they would be the only one anyone ever bought.

[@Autofaze]

For sure the price is insane on them right now! Appreciate you watching!

[@MrPacha098]

Did you guys use the same 60 trans shifter cable and bracket?

[@Autofaze]

Trans bracket was modified a tad. Thanks for watching!

[@DanielRivera-td7cd]

If I swap my tranny on my Maro, Do I need to reprogram the ECU? or after the change, the pinout will be like plug and play?

[@Autofaze]

Yes, you will need to reprogram when doing the 80e if you want the pcm to control shift points

[@MRGCustoms]

Did you delete the torque arm with the swap?

[@Autofaze]

No, we switched to a tunnel mount before going 80e. Thanks for watching!!

[@brycegarrison2028]

What slip yoke did you guys get? You listed everything but that

[@Autofaze]

We didn't list it as we don't know if we will need a new driveshaft yet. I can look it up for you if your still interested 👍

[@brycegarrison2028]

@@Autofaze yes! About to pull my trans this weekend and if I need a different drive shaft that would be helpful to!! Please and thank you

[@Autofaze]

Sonnax T3-3-5571HP is the yoke we are using. You will need a conversion u joint.

[@johnsimmons8456]

@@Autofaze Good call, that yoke has full spline engagement, I always recommend a fully splined output and that yoke for 4th gen to reduce vibration.

Know anyone that has put a ZF 8HP70 in a fourth gen???

[@Autofaze]

Sure dont!

[@PoppaSmurf3054]

Any cutting needed if you use a 4l60 instead?

[@ThaProfeshional]

?... the car comes with a 4l60. it goes right in, if that was your question.

[@Autofaze]

No cutting if your doing a 4l60 swap on a t56 car

[@brycegarrison2028]

I see other people using a 4l80 umi performance crossmember! How and why are you using the 60?

[@Autofaze]

What do you mean? We used the Midwest chassis 80e crossmember

[@JoshuaGrooms83]

I'm curious as well. Does anyone know if umi has a crosmember that works with their torque arm? I have their setup that takes it off the trans already, but id hate to have to swap my umi adjustable torque arm on top of already expensive trans setup

[@THATMOFODIRT]

Good stuff.

[@Autofaze]

Thanks for watching!!

[@mikeverything4098]

How much did it cost in total

[@Autofaze]

For this exact setup a hair north of 4k. This could easily be done for high 2s or in the 3s though. Get a cheaper converter, reuse your aftermarket 60e cooler, rubber transmission lines, ect. This car already had a chassis mount tq arm that we put on in 2020. Your biggest $ items will be transmission and converter.

[@jamieduckworth5946]

Can't wait to see the turbo. That car is gonna be sick
