LS4 Tech: 4T80E Swap - Electronic Control Options & Full Manual Conversion - PT 3

[@1320orRoll]

Glad you're sharing the information to help make other LS4 guys more reliable and faster if they're modded. Glad you're not holding on to the information. The Ls4 guys need this kind of information. Great video

[@LS4King]

LS Crazed thank you! Happy to help.

[@conncorey1066]

Man I'm so glad you shook back. You are a pioneer in the wbody community!

[@LS4King]

Conn Corey thank you 🙏

[@ktwosrt8life]

Everything you do is absolutely amazing! You’ve been so much help I got a transmission out of a DTS 2006 I can’t wait to get started on my 2006 impala SS

[@colebriden8548]

Thank you for the wiring for the 3800 shift logic. Ill have to try this on my 3800 swap

[@LS4King]

Cole Briden no problem!

[@tptrsn]

You are a champ!! Seriously inspiring me to forge ahead with a ridiculous project I've had in my head for a while, but I didn't quite know what drivetrain to use until now. Subscribed!

[@KevinShannon-v4s]

Great info here thanks. I am considering a LS4/4T80e full manual shift in a sand car project looks like your videos will be a big help. Subscribed!

[@dailycivicsi9295]

Great informative video,does nothing for my honda but watched anyways lol,keep up the good work on your channel

[@LS4King]

JDM jeff plenty of good info for your honda! You just have to LS swap it first! 😂 - all jokes aside, thank you 🙏

@@LS4King do u still sell the rear mount that elimate the dog bones?

[@John-cw4lz]

Thank you for doing this and sharing it. If I understand this correctly, a 3800 TCM pinned to the 4t80 correctly (as you lay out) will run the 4t80? As in once i get past the caveman part i pin it out and plug it in and fine tune from there? With the relay trick of course.

[@jaybrown679]

Thanks for the info... do you have a known to work pin out for a 70 to 4L80 swap with a T42 E38 06 tbss ...theres no info out here for this one ive looked for days and im so close to getting it to work...im missing something small somewhere thanks again for your videos

[@civicsr2cool]

Great and thorough video! Any experience on an f40 g6 manual trans with an ls4? It supposedly pulls the motor a lot closer to the trans and packages better in Fiero/Corvair swaps.

[@LS4King]

CivicsR2Cool i have a new F40 at the shop and I have bolted the two together, but i have yet to use it in anything. It is very compact for sure.

[@el_7017]

LS4 King you think it will be possible to put a 6T70 transmission on this ls4 engines

[@LS4King]

@@el_7017 Yes it is possible, but I have no experience with how "durable" those units are.

I trying using the links in the subscription however they are nit allowing me to view them

[@TheBPHero]

Would it be possible to retain the tap shift stuff with GXP models?

[@LS4King]

The BP Hero if you inverted the shift logic and used the relay method I show in the PDF...yes...you could retain the 4t65 file.

[@TheBPHero]

LS4 King I thought that’s what I had picked up from what you were saying, but wanted to make sure! Loving the content man!

[@LS4King]

The BP Hero thanks dude!

[@woodydouglasv9185]

@ls4 king so basically for someone that has 06 ls4 MCSS for a daily would it be easier to just invert the signal with a homemade harness and not worry about a tune. I have a 06 MC I just got but the trans is doing the once in awhile slip at start, and overall shifts strange. I drive about 100mi daily to work. And want a trans that is worry free. Would this be the easiest and work.

[@CruisinComPTon]

I have a stock 07 GP GXP. i just want a reliable trans to keep using it as my daily driver. So it seems going with a later model 4t80e would be the easiest solution. When I go looking for one, do I also grab the TCM or use my factory TCM? Sorry not too knowledgeable about this part but i learn quick

[@LS4King]

Cruisin Compton I would grab the TCM from the donor vehicle you snag the transmission out of.

[@tec9tjguntek]

Will a late model 4t80e still shift without the Internal range switch connected. I have a standalone controller and for 4l80e/4l60e and I believe it doesn't have range switch pins.

[@LS4King]

sam Davidson yes it will still shift

[@projectgattago]

Am I correct in thinking that something like Holley Terminator X Max with the trans control for a 4L80e will work on the 4T80e?

[@LS4King]

Yes, it’s been done multiple times.

[@projectgattago]

Thank you.

[@red92da]

Is it possible to control the transmission and use a different engine aside from a gm?

[@LS4King]

With a standalone controller yes. Honestly you could probably make a TCU from a late model cadillac work stand alone if you could supply vss and rewire it.

[@jamesmenge6214]

If I wired it to manual shift, would that work if I installed an actual manual transmission like a f40 or f23? Thanks for your help

[@teocummings808]

Hey I wanted to find out something on the 4T80E transmission that I have the housing crack, now we got another transmission same number but the difference in two transmission is that the extension on the transmission to jack into the harness is different. The plug in from the new one we got is different to the other one, I'm studying to swap the two valve bodies, the electrical wires and the shifter rod because the one I have has a groove for the sensor while the other one is smooth.

[@gailliardander]

Thank you

[@obetztyranthunter]

Will this concept work for the 3800

[@Ranja1930]

Hey man! Been keeping up with your vid's about the 4T80E swap since I found them. Really appreciate all the information! great video's all info to the point and easy to understand. So thank you! I've got my hands on a 06 Grand Prix GXP 245k (crazy) and i've been working on suspension and chasing down some electronic gremlins. but otherwise car runs fine. I was told it's is on it's 2nd tran's and since I've been watching your vid's I'm trying to wrap my head around this swap. What kind of price difference are we talking about, once the job is complete. vs a strongly rebuilt 4t65e. if I'm not out to make big hp numbers like you're cranking?? If you read this I really appreciate the thoughts. I took a look at the holley terminator x. and if that replaces the entire main engine harness and gives you the new controls i mean. that is almost a no brainer. (after 245k the wires under the hood are basically cooked and causing gremlins). Any thoughts on that as well? I appreciate the help man. LS4 life!

[@Ranja1930]

Also just read you were in an accident recently, Hope you get better soon man! Heal up! We need you out here crank'n them wrenches!

[@onikisusalt3665]

I'm in pretty much the same spot right now. What did you do? How did it end up?

[@heribertogarcia3670]

Sir would the ls4 swap work on my 98 cadillac deville it already has the transmission you recommended. I would be interested in manually shifting as well.

[@LS4King]

Anything will work with enough time, money, research and dedication. Im sure your projected project is more than feasible.

[@heribertogarcia3670]

@@LS4King do you think the mount you make would fit into my projected project?

[@coachablebean3345]

What all soft wear and parts would I need to do this? I have an 01 monte carlo ss I'm rebuilding and the trans will not shift through all the gears only first and 2nd with the trans plugged in and unplugged it only shifts 3rd and 4th would love to make it full manual like this

[@CantHaveEnough]

If I heard you correctly- I can still use a 4l80e code segment on a factory p01/p59 style ecu to run a post 99 4t80e even though there's electronic differences between the 2 gen.s? Any hiccups to watch out for? Thanks

[@Shadow0fd3ath24]

Do 4L60e and 4L80e shifters work with these FWD 4T80e transmissions?

[@LS4King]

As long as you correct the shift geometry yes. In other words you just need to make some brackets.

[@DrakroxT]

Is it possible to swap 4t80e on my impala ss and still use it as the 4t65? I mean having the "D, 3,2,1" gears. I Just want to use it for daily drive.

[@TheProchargedmopar]

👍✅

[@kevinhumphrey932]

Would the 96 model year be a good transmission for swap and still have the tcm control the shifts rather than manual shift the reason I asking about the 96 is a few years back I installed a remanufactured transmission in my neighbor's caddy about 1500 miles later she over heated the engine I can purchase the complete car for 500 bucks thank you for input and reply

[@joshuamcneil7349]

N body 00 GA GT1 LS4/4T80e Are you saying if I follow exactly what you are saying to my 4T80 and get a shifter and kit for it it’ll be manual??

[@LEGOCAMARO]

So will the Holley with the transmission control work? Or do you need a 4t80e trans controller regardless on the ecu?

[@ImMrKuzco]

What about an F40?

[@chocolatcolumbo9484]

how hard would it be and what all would i need to do an f40 trans on a 2008 grand prix gxp?

Any advice for the W body 3800 guys..?

[@chuckfults9256]

LS4 king, back in the day, we use to call that switch on the shift shaft of the transmission the Prndl(prendle) switch ...just sayin

Can we just pay you to put or swaps in

Eventually when i recover from my accident!

[@meechdouble4297]

I have a 2007 Grand Prix GXP (4t65e) and I have a 2002 cadillac 4t80e transmission. I wand to run it stock. Will the wiring harness that you referenced to in the video work that's made by pcm of nc ??
