Great video! Thank you.
I'm glad you liked it!
Thank you for taking the time to put together this video. Everything is so well laid out, very good visual aids, and you sum up hours and hours of r&d i one 17 minute video. Very helpful to the community.
Josh Schattenkirk no problem and I am really happy you found it useful.
I built my own 4T65E. Zzp input and output shafts, reinforced baskets, kevlar clutches, TH125 chain and sprockets. Drilled spacer plate, transgo shift kit, sonnax boost valve, 12x12x1 plate and fin cooler. Got about 10k on it now putting down 380 wheel daily driven
Yo where did you find the TH125 chain and sprocket at
How much to rebuild my transmission like that?
I'm loving it. Makes me wanna put an ls4 in my caddy
This video will be very helpful for so many people looking to upgrade to a stronger transmission.
I certainly hope so!
I use both you guys for my knowledge
Glad ya'll are finally recognizing the 4t80e as the most robust option.
Nice and thorough with the tidbits.
Much better with many of the "soft shift" valves deleted internally....they really went to 11 with the NVH compromises/features for the finicky Caddy buyers.
Someday we'll look at two ls4s for the 442
I FOUND THE PERFECT REPLACEMENT FOR MY TURBOED AND BLOWN CORVAIR STREET BUGGY
These videos are really not helping me forget my long time desire to build an LS swapped fiero...
My LS4/4T80E Fiero should be on the road soon! You can find my build thread over on PFF
Such an in depth video, Thanks Brandon!
While I don't see using any of this in my future, I watched anyway and found your video informative and very thorough...Thanks!
he really is the ls4 king, ive never gained so much info about this fucking engine and tranny ever.
New to the LS4 game… I’ve got a very special and unique project I’m gonna use mine for, so I appreciate your videos!!
nice stuff,,,if i ever go this route he seems to be the go to guy for all my help
This man's knowledge is amazing
Thank you!
Excellent video one of the best I've seen thank's
Can't wait to do this to the monte carlo ss my dad left to me when he died I've been talking about doing this for years thanks for the vids of all I need truly helpful
What year
A Wealth of Information!!!.....You Should Publish Your Own Workshop Manuel!!!.......Great Idea!!!.........Good Luck!!
Dude you saved my pondering thoughts😂 I have been hearing I can swap my 4t 65ehd with a 4t80 but been so lost on how but you helped
That looks super clean and ready for some great performances. I have the 5.3 with an aftermarket remanned 4t65e hd that I ended up going with after my previous 2 transmissions were shredded to pieces. Still holding onto the road with an 06 Impala SS for 18yrs now 🤞🏾🤞🏾
Very well done, highly informative.
We just installed it on Eric's 07 SS.. SUPER TIGHT FIT, VERY HEAVY TRANS, but we got it no sweat, and we used your solid subframe mounts
Yea, that 4T80 is a monster! Glad you guys knocked it out!
@@LS4King we had the subframe on the ground on "rollers" set the engine and trans down onto the subframe (after some light shaving for clearance) lowered the car down then caught 4 bolts... Nice n smooth👍
thanks for the great video
Very informative I told my boss im omw before this vid started haven't moved.. Splitting this off a North Star Seville 04
Awesome video.I watched your first transmission video. And you talked about the starter mounting location...
Hurco VMX42 Thank you I am going to be doing a separate video that just discusses the starter as the main topic
@@LS4King awesome, And I really like that provision prototype you made with the plastic printer.. I live in Michigan I wish you were closer I'm a journeyman 3D tool & die maker.for over 30 years. We definitely could make some stuff. Again Super job on the videos.
@@hurcovmx426 That sounds like a cool gig! Thanks for the support!
Wow. Very nice.
Thank you!
This is very good to know once my Northstar blows up I’m going LS4 in my caddy but for now I build up my Northstar but I’ll have a LS4 at the ready
@LF X Yea once studded those things are bulletproof lol
This is awesome, planning on swapping into a X-Body. You can beef up the 4T-65E HD to handle the power ZZP does this and many others. My issue would be the plumbing but the front cover solves that issue. I'm going more a simple small block 383 N/A but this is all paper planning. Anyways great content and can't wait to see the finished product.
HOw can you strenghten the 4t65e?
@@w41duvernay check out zzp's website but you can run a hardened input and output shafts, oil pump shaft, 1-2 clutches and gmr 1 inch chain replacing the double chains which is it's weak point.
Nice caprice in the background
Are certain ratios better than the others? I just found a 3.11 at a junkyard for $200 with 123k miles on it. From a 2000 Deville.
Very nice design of mounts! Dam when you said get rid of the dog bones I start smiling. Lol, I have a 3800v6 s/c. Unless I swap motors.
Great and subbed!
Thanks!
I'm wanting to do the 80e swap on my l67 so bad I'm tired of going through transmissions. Hope you can come out with a swap video for them in the future
We may have something in the pipeline with GM EFI Magazine!
That would be lovely I'll be lookin forward to it. 😁
I've owned 2 white Caprices just like that one in the background
Concerning the torque converter... How much space should be between flex plate and convertor pads to allow for converter swell and proper pump flex on input shaft?
Could the length of the detent arm (where the cable hooks to transmission) be changed to keep stock 4t65 shifter?
Dune buggy, here I come!! Hell yeah, brothereeeerrreeeerrrrrrr!!!
your answering a question I've had for a while, like can a transverse transaxle take big power back in the day I knew the answer but do the modern ones fare better?
I got a 06 Buick Lucerne CXS with a Northstar I was swap a modded ls4 in it .
What about trying to bolt it up to an L67 in a W body impala..? I'm not happy with my 4T65E, and for some reason, the 4T80E is cheaper than a reman 4T65E-HD. Any help or parts list would be MUCH appreciated. As well as trying to tune it to the OEM computer.
Serious question….do you think this engine would bolt up to any Fwd/Awd import transmissions? Like let’s say a DSM Mitsubishi Eclipse Auto Awd trans? And also any 6/8 speed gm Awd trans?
Do you know if a f35 transmission (5 speed manual cobals ss trans) will mate up with a ls4?
How much would you charge to do this if I were to provide the engine, trans, and frame I have a LT 3.5 I want to swap
Hmmm...LS4 and a 4T80 in the bed of my S10. Here goes my savings account.
Niiiiiiiiiice work
Does the 4t80e swap allow you to keep the paddle shifter functionality?
Unfortunately not, but it's a worthy sacrifice.
Is this trans strong enough to run in serious tow application thinking about old 70s Eldorado subframe and suspension to make a fwd coe or van front cab with a trailer style dual axle flatbed car transporter seen one used a lumina front with the cut behind doors to haul a speed boat
If all eternal parts are the same as a regular impala SS or Grand Prix GXP transmission can I use them parts from the Cadillac transmission to rebuild my original one in my impala ?
What kind of axles do you use?
Hi do I need the trans module and do I need to re-pin it to keep automatic do you have a video and also do I need a tune after that
I would like to put an LS four into a 2002 Eldorado get rid of the Northstar is that possible
What intake can I put on my 08 LS4 to have better flow
Would the ls4 bolt in to a 2000 grand prix GTP? What kind of modifications would i need if not?
Hey can i put this setup in my 67 cadillac
Ls4king my 4t65e GXP trans just got rebuilt with a high stall torque converter and shift kit what Brian Tooley cam or any other camshaft can I use?
what is the axles or cv joint combination for a v6 wbody impala?
How much would you charge me for a ls4 engine with a 4t80 ready to install in a 07 monte carlo ss?
i didnt see anything on the starter in this video...where do you put it now??
Do you do these modifications in your shop, and if so, where are you located?
Question is, where do you mount the starter? I don't see the starter on the video
Is this a swap that would be possible for a 1996 cadillac seville
What it takes to swap ls4 into 95 eldorado if have whole donor car with ls4. Is Impala LS tcm will connect to 4l80 external neutral safety switch or I need get whole another late model 4t80 with internal switch? What it take to make 4t80 functional with ls4 ecm tcm
So I bought an ls4 not knowing what I was looking at and I my idea was to put it in my Jeep . I do know that the bolt pattern on the ls4 matches the bolt pattern on a 60 degree 700r4 would you know if I could make that work as far as fly wheel, your oil pan starter provision or another type of starter set up . And lastly I’m sure I could get the motor mount situation fabricated. Could you let me know if it seams possible to do I can’t find anything on any forums about ppl finiothis type of project
Would this whole set up too big for a 2005 Toyota Camry engine bay?
Hm..I wonder if that 4T89 could be mated to a 4.3 vortec v6??????
I want to put an ls4 in my 99 Cadillac. Will it work?!
Have you ever made it successful in a 1994 Buick GS 2 door coupe ?
Youre making it hard for me to keep my Impala stockish😂 I need her as the daily but I want to build it now more than ever!!
I remember you talking about starter location in the last tranny swap video, what ended up being the solution?
The solution is to still relocate to the oil pan. I will be doing a new video next week highlighting the pas I have dropping in 2020
Waaaait a damn minute are those 317 heads ported and welded? Is there anyway you can give a bit more info on that lil trick?
How can I get the mounting plate for this set up ?? I want to run my 2007 Gxp as a automatic but I just want to hold the v8 power
How did you do the starter hook up?
Hats off to you sir nice discovery!!
And I thought swapping a Tremec T56 into my 09 LS4 impala was a bitch , cracking up, I wish . . Anyhow that trans does look pretty dam stout
Thanks!
》▪︎One way that could make the tasks of the swap easier for you is to create a program for both the LS4 & 4T80E and have a CNC Mill automatically trim away all of the unnecessary fat from each piece. Might take some time but would be more efficient and helpful to others.
doubt is with this GM 4T80E Transmission Swap. The Chevrolet LS4 V8
is, instead4T65E ( That couldn't even handle the HP & Torque from a 3.8l V6 The Owner & Host of this Awesome TH-cam Channel, 》
use with a CNC Mill
What is the cost for the Pan, mounts, etc?
Please email me for pricing and availability brandon@ls4king.com
Will it work if i swap it in a LUMINA Z34 EURO
any update on that converter you were working on getting made? also just a thought could they make it work with the ls4 flex plate? or make a 4 bolt flex plate to mount to the ls4?
Precision did a hybrid converter for me. It has the "guts" of a 4T80E, in the shell with a billet cover of a 4T65E. They were really cool about working with me on it. Charged me 1k at the time (about 2 years ago?)
SO it bolted up to my stock LS4 flexplate. To Brandon's point, trying to get a billet one made is tougher. I talked with Meziere, they do have a drawing for one, but you'll notice from the edge to center the LS4 flexplate has two "steps". The one they made only has one. They had me take a boatload of measurements to make sure theirs would work, but after all was said and done, they were only about 90% sure there wouldn't be any interference issues. So sticking with the stock one for now.
Can i use the dog bones still ????
I want to shove this combo into a U-body (04 Aztek). Besides the obvious question of why someone would juice up an Aztek, I am a road Troll. I don't rage on people, I just like F>
Do you have to swap the transmission
How about this set up in a lambda platform?
What final drive are you running in your monte? I'm looking to put a similar setup in a fiero.. wanted to see if you could help with a recommendation. Figured I would come to the king.
mondo mondo i am running the 3.11 with a 26” tire. It depends on your needs.
3.48 might be nice if it’s lighter snd less power.
How much for one of those transmissions that will fit on my 2008 Impala SS?
Are all the shift control logics of the 4l80e (line pressure, pwm for lockup frequency, ect.) the same as the 4t80e? I have a standalone controller for the 4l80e so that should work for the 1999 and down 4t80e right
That's all correct
Can I do this swap in a 98 Cadillac deville??
I bet you get a lot of questions regarding a swap from the 4T65e to a 4T80 with a V6. I only ask because I have a friend that wants to build up his SC'd 3800 Bonneville.
Thanks for the video. Got a ?
Will an ls4 work with a versatrac awd drive train?
With my oil pan conversion I don’t see why not!
Could I run it mid mounted how do I get your mounts
cool
Excellent job !! Would love to install into a late model Ferro … with custom mounts and axles. Would be inline of being a Supercar at 1000HP!!
Can the auto Tranny be set up for paddle shifters? Is there any close ration gear sets that can be used for racing and or off road options ??
What max power can it handle ??? If I ProCharger or supercharge it it could go north of 1,000 HP …. Advise
Keep them coming !!!
Hey Glenn! Thanks for the kind words!
PCS does offer a trans controller with the option to integrate paddles which would work excellent. Unfortunately at this time, there are no aftermarket gear sets.
As for power handling capacity; I have personally put over 800whp and 700ft-lbs through a stock unit with unknown mileage problem free.
I think a carefully prepared rebuild would easily support 1k ft-lbs with the normal tricks.
@@LS4King awesome. Very interesting idea. Thank you ..... for sure will put you on my Dial List when I start the project. BTW - love the 3D printed spacer block. Excellent innovative and as an aerospace engineer I love seeing this in Gearhead threads!!
Best of luck
@@glenningram9962 thank you sir
I'm trying to do a ls4 swap in a buick lesabre can u help with info and maybe someone in Texas that might do that type of swap?
what is the realistic list of advantageous doing this over a built 4T65? Any disadvantages?
Rick Dangerous it really comes down to your goals.
Under 400whp you could throw money at a 4t65 and have it probably stay together. Anything over that and you are playing with fire in my opinion. That is where the 4t80 comes in.
The downside to the 4t80 is just how labor intensive the swap is.
New sub here I want to do this swap on my channel I have question will the new subframe bolt to the same spot on a 2002 grand Prix gt? And is the Northstar trans stronger than the SS trans?
More than likly and yes
I'm thinking a mid engine GM version of the Ford Shogun. Maybe a Metro...
Shit Shower that would be insane!
You guys building these for rear/mid engine drive vehicles?
I have an extra 71 Ply Satellite/Roadrunner I'd like to convert to mid engine.
Make a street car wheelie machine. 😆
I am actually in the middle of swapping my best friends Fiero!
LS4 King That's gonna be insane!!!!!
@@LS4King serious business would you do this for me and if so how I get in contact?
Howdy Brandon! I just sent you an email regarding an LS swap into a Northstar Cadillac.
I have a 2005 GXP with a 5.3 what year of transmission should I look for 93-99 or 00-up and is it possible to make the tap shift work when using the 4t80 one last question do you sell your conversion brackets braces etc to do the conversion thank you
Hey Kevin, please email your questions to brandon@ls4king.com and yes i sell all the parts
I was wanting to put a ls4 into my 90 umc aeromate what would I do to make the computer work
I would just put it on a standalone.
on your lower bellhousing ear that gets cut off,, have you ever considered Tig welding up a different style boss and drilling then tapping a new higher mounting hole,, even if the hole is a little sketchy you can alway install a helicoil and with any luck have that lower hole mountable.. I see your 3D printed adaptor you made and I get the function of it but I just wonder if welding and making a new mounting hole would work
It's certainly not a bad idea...but it is most likely far beyond the average enthusiasts skill level. The clamp is a solution that the average guy can just bolt on for some added insurance.
@@LS4King absolutly,, and I highly believe the clamp will more than help in all situations,,I guess I am lucky that on a daily basis I do my share of AC Tig welding and have no fear of aluminum material,,, hence my job fixing tire molds.. and you are correct,,, slamming the pedal and laying a row of aluminum is not up to everyones skill unlike pulling the trigger of the mig welder,,, and even at that I have done alot of AC mig welding in my work career,, I wish we were closer I think our combined skill of fabrication and welding we could rewrite the LS4 world in its potential
@@LS4King I also forgot to ask,,, and I believe i am talking to the correct guy,,, I follow your buisness facebook page and I seen where you posted you was in a nasty wreck,,, you doing ok now
jeff king yea thats me haha. Im doing okay thank you for asking. It’s a long slow process
I was told only transmission that would work in mines is a 2006 as trans
Well, this means I can confidently LS swap my Cadi Deville! 🤣🤣
Have you done yr Ls swap yet? I want to do the same.
Same here on 06 impala lt
is a 6t80e swap a thing?
Can the 4.8 Vortec mate up or fit with a 4T80E in a Front Wheel Drive Impala?
Hey I'm trying to swap a LS4 in my 1999 Cadillac STS. Will those mounts work for my subframe
Unfortunately they will not
