LS SWAP WITH OLDER GM TRANSMISSION

[@brandongibson85]

Dadgum folks he even drew ya pictures and broke it all the way down for ya. Listen to learn not to reply. Thanks for the info man I'm in the process of swapping a 72 nova four door with an LS, going with the original 350 tranny that came in it, rebuilt of course, and a 4000 converter. Should be a fun one

[@BadLuckGarage]

Finally someone who pays attention! Lol. Ironically that’s the same combo we started with in Chaos Theory, right down to the th350 that we pulled out of the DR Nova when we swapped it!

[@brandongibson85]

It's gotta be frustrating for you to keep answering the sane things repeatedly. Don't let them chase ya away from making he videos man I appreciate everything I've learned from them on my lil journey. I'm putting a 4.8 in mine and my intention for it is to be a street driven, drive it to the track( i57 dragstrip in Benton Illinois) to bracket race it.

[@BadLuckGarage]

@@brandongibson85 Brother when I started this channel years ago it was to help people help themselves. What I’ve come to find out is a lot of people don’t want to help themselves. They want to be spoon fed and your time means nothing to them. People will click on a video that seems to be about what they need to know, never watch one second of the video or skip through missing all the important bits, then ask questions that were already answered in the video. Then when I tell them to watch the video they get pissed like I’ve got time to type out answers for 150,000 people when the answer was already in the video. This video is a perfect example of that if you read through the comments. Are used to reply and let them know the answer was in the video or if the answer is in another one of my videos I would just post a link to that video. But now days for the most part if it’s obvious they didn’t pay attention I just don’t even reply. It’s just a waste of time. My parents always told me “You can’t help those who won’t help themselves.” And if I tried to take the time to re-answer every question that was needlessly asked I wouldn’t have time to do my read job. I’d literally be sitting on my phone 22 hours a day.

[@BadLuckGarage]

@@brandongibson85 Just curious, have seen seen our DRNova project? That car is literally my uncles daily driver. Cruises nice, gets around 22mpg and runs CONSISTENT 7.84s in the 1/8. And when I say consistent I mean the it ran 3 7.84s back to back to back. Lol. I told him we should pull some timing out and get it doing solid 8s or 8.50s and let him bracket race it.

I have a 4l80 trans and a 4l80e converter that is supposed to work with a 4l60e dished flexplate. Everyone swears my 2002 silverado 5.3L has a dished flexplate and it doesnt and I've taken this transmission in and out 3 times. Trying to find a dished 4l60 flexplate local. I actually put the 6.0 spacer behind the flat 4l60 plate and everything fit perfectly except none of the starters I have will reach the ring on the flexplate.

[@BadLuckGarage]

Sounds like you’ve got some weird fuckery going on. Possibly something done by the previous owner. If you’re using an aftermarket converter then call the converter company and use whatever setup they built it for.

have a 6.0 with a longer snout on crankshaft and wondering witch flywheel to use when using a th350 so i do not have to extend holes on flywheel, dont know what year motor it is, i followed your advise on your flywheel video and bought proper one for the 5.3 i was going to use. thank you love your vids

The dished flex plate in my swap came with 5.3 from a yokun 2003 also I've an 03 silverado 4.8 also has the dished flex plate 🤔 maybe the difference you mentioned could be in 99-2002 models? But the bolt pattern for the flex plate to the tourque converter is there i drilled it with a cone drill bit.

[@BadLuckGarage]

As I explained multiple times, the engine didnt determine which flexplate you have, the transmission does. You seem to be misunderstanding alot of what I said in the video so I'll summerize again.....4L60=dished flexplate, 4L80=flat flexplate. Engine doesn't matter.

[@rafatrill]

This great information, what about for a 700r4 transmission?

[@BadLuckGarage]

700r4 and early 4L60 used same bolt pattern as a TH350. So unless you get a converter with dual patterns you’ll need to grind the bolt holes a bit. I edited that info out because a 700r4 makes zero sense to do in an ls swap when the 4L60e fits exactly in its place and doesn’t require a tv cable or crude lockup techniques.

[@rafatrill]

@@BadLuckGarage well I have one that was currently rebuild and works great. I was just going to used it in a daily driver build. Till it breaks then upgrade to a 4l80/6l80 what ever I can find

[@BadLuckGarage]

Like I always say brother, it’s your build so you do you. But if it were me I would sell the 700r4 to someone and buy a 4L60e or better yet a 4L80. The 700 is going to require more work and money as you’ll need to buy adapters to properly attach the TV cable to the ls throttle body and there’s the flexplate grinding, and you’ll need to purchase the lockup kit to control the torque converter lockup since it lacks the computer controlled lockup. Or you can wire it to a toggle switch and lock it up manually while cruising. We used to wire them up that way back in the day. Just don’t forget to unlock it when you come to a stop. Lol.

[@rafatrill]

@@BadLuckGarage how much u think I can get for a rebuild 700r4? Less than 1000 miles

[@longbow60435]

I have a 93 chevy 350 4l60e,,,just rebuilt,,,the flexplate has that butterfly weight on it,,,since I got it back from the trans shop it has a wobble in the van,,,that weighted flexplate is what is called for in my van g 20,,,,why doesn't your flexplat have a weight?

[@BadLuckGarage]

Because a 93 4L60 flex plate is totally different than a 99-up LS style 4L60e flex plate. Your 93 4L60 is basically just a 700r4 with a new name and some extra wires. The 99-up 4L60e is a completely different case with interchangeable bellhousing and “upgraded” internal components and fully computer controlled.

[@goober2021]

I am putting a 5.3 ls in s10 and running a 700r4 and I went and bought a flexplate for 2004 chevy 2500 HD with 6.0 with 4l80e trans.it would not bolt up to my torque converter on my 700r4 unless I modified the holes.

[@BadLuckGarage]

That’s because your converter has a 10.75” bolt pattern as explained in the video.

[@goober2021]

@@BadLuckGarage do you think it will be OK to modify the holes on the 4l80e flexplate since I have already bought one? Hey man I sure enjoy your videos I have learned alot watching your videos.Thanks.

[@BadLuckGarage]

Like I said in the video, people do it everyday brother. I probably wouldn’t trust with on an 800hp turbo build, but for a lower power NA build it should work just fine in my opinion. There are companies such as speedway that now sell LS flexplates with a 10.75” pattern for around $70-$80 though. So that’s a lower budget option you have now that wast there back when I first made this video. 👍 Glad you’re enjoying the videos too brother.

[@JKlife760]

Hey so I used the flex plate and bolts it came with and got it all bolted up. I can’t spin the torque converter because the torque converter stub is hitting the bolts that mount the flex plate to crank. I’m going to try the oem bolts that I off the dished flex plate see if it clears.

[@BadLuckGarage]

B Hinz sounds like you don’t have your converter fully seated into the transmission. I’m also not sure how your converter snout would be wide enough to make contact with the bolts. That makes no sense to me.

[@JKlife760]

Bad Luck Garage The converter is fully seated in the transmission. I figured it out it was the flex plate mounting bolts. I meant to say that the snout on the torque converter is welded inside the dish part of the converter. Well the dish part was hitting the bolts that came with the flex plate. It was grinding on the dish where the snout is welded to. The oem bolts are shorter at the head by 1/8 of a inch. When I put the oem bolts in the torque converter was able to spin. Thanks for the tip on the flex plate though. Everything bolted right up. No shimming or anything.

[@BadLuckGarage]

Glad you got it worked out brother. Yea you had me totally confused. 🤣

[@TheMrVad]

[@Dying2Live220]

So, I have a customer car with a customer provided 6.0 with the long snout. I have the flat flexplate (no spacer) with a th350 going behind it. What do I need to adapt it. My concern is the torque converter snout. Thank ya.

[@BadLuckGarage]

@@Dying2Live220 This is one of the reasons I said in the video that I avoid the long crank flange engines. Depending on what torque converter you use, it may slip right in or you may have to do some grinding to make it work. The good news is as long as the converter has an 11.5” bolt circle, you should be good with all other clearances and it should bolt right up to the flat 4L80e flexplate without any adapters.

[@Dying2Live220]

@BadLuckGarage yeah I heard you mention that, I think someone ground the snout of the converter so I'll probably be replacing it. I don't like how much clearance is in between it and the crank. Thank you!

@@BadLuckGarage might be better to replace

[@BadLuckGarage]

Yea I personally don’t see any benefit in using a 700r4 in an LS swap, only negatives as it creates more problems, especially in regard to the TV cable and it doesn’t take advantage of the computer controlled shifting and and tuning that the 4L60e or 4L80e would be able to. Matter of fact the ONLY time I would personally see it as a feasible option is if you were going to be using a carb setup instead of the fuel injection.

@@BadLuckGarage I am using a carb. Also I'm using stock speedo cable. And I have the transmission. One swap combo does not fit all

[@BadLuckGarage]

@@332ARA Thats what I just said, If you're using a carb then it makes sense. If you kept the efi then the 4L80 would make sense and be the cheaper option. You're choosing to run a carb so slot those flexplate holes and throw the 700r4 in since you wont have the computer to run the 80 anyway.

[@Chupapi1990]

So is this the same for a 700r4? Never heard you mention it.

[@BadLuckGarage]

700r4 uses a 10.75” torque converter bolt pattern like many other transmissions. That’s what’s important and that was explained in detail in the video.

[@notsure7874]

Alright! Now my only issue is that torque converters in the aftermarket seem to LOVE that 10.75" bolt pattern. Be nice if there was a 4L80E flexplate drilled for that.

[@BadLuckGarage]

What transmission are you using? If it’s a th350/th400 then either use a th400 specific converter or a dual pattern th350/400 converter. If it’s a 700r4 or pre99 4L60 then you’ll have to either slot the holes as explained in the video or purchase an aftermarket flex plate.

[@notsure7874]

@@BadLuckGarage th400 - which is why I'd want to use a 4L80E flexplate. Here's the issue: the 11.5" and dual pattern torque converters I'm looking at (Summit, and I think I looked at Jegs) are nearly twice the cost of a 10.75" TC. Lots of aftermarket TC's for th400/350 only seem to come in 10.75", So I'll be using the dished 4L60E flexplates I have, and slotting them, I'd just rather have the holes drilled in the right spot (on an aftermarket 4L80E type plate) and not have to use that cheesy adapter or weaker plate. The Dirty Dingo flexplate other than being SFI rated, is nothing more than a 4L80E plate with 11.5" hole pattern. I just don't get why they wouldn't drill both holes if they're going to the trouble of making a plate and getting it SFI rated and whatnot. 100% I'd have bought that plate if it was double drilled.

I have a 97 4.3 2wd Gm pick up and my transmission went out. I have a 2005 2wd transmission and I was wondering if I can use that 05 transmission to my 97

[@BadLuckGarage]

No

[@georgerose3187]

now what can be done about a kickdown cable ?

[@BadLuckGarage]

Don’t run one or make a custom cable and bracket.

Have you had issues with start getting stuck on plate I have 5.3 on a th400 transmission

[@BadLuckGarage]

@@drewdowncutomz4792 nope

[@eduardomontanez4661]

Can I use the converter from my 4l60e transmission with the flex plate in my 350 turbo transmission, thanks for sharing

[@BadLuckGarage]

No. A th350 flexplate won’t bolt to an LS crankshaft.

[@eduardomontanez4661]

@@BadLuckGarage you misunderstood my question?

[@BadLuckGarage]

@@eduardomontanez4661 I think you misunderstood the title and intent of this video.

[@obsant7214]

Everyone that needs flex plate and a adapter Jegs sells the set for the LS to older gm trans for $135 that’s all you will need to bolt it up

[@BadLuckGarage]

You can buy the 4L80 flexplate with spacer and bolts for less than $70 from most auto parts stores brother. Why would you want to pay twice as much from Jegs?

Great informational video thanks

I'm swapping a 2004 Cadillac Escalade 6.0 into a 97 chevy silverado and the flywheel from caddy wont bolt up to the 4l80 in the truck so that flywheel from 4l80e will bolt up to it thanks

[@elinino5275]

I found one of those with the spacer at O'Reilly. Wtf I had already bought the aftermarket spacer lol. I didn't know they came with a spacer. I'll be darn!

[@BadLuckGarage]

Yep they come in a kit. Should have come with bolts as well.

[@jeffmentzer6550]

will the 700r4 work with the 4180e flex plate

[@carlospayen9965]

I have a 99 chevy astro 2wd I have a 4l60e from a 2004 silverado 2wd is this 4l80 flexplate doable.? Thanks by the way my van is a 4.3 vortec. Thanks again 😮

[@shipmannorthcutt9226]

Very helpful.... when I sourced the 4l80 flex plate ATP# Z270. The TC bolt pattern was to big on the flex plate. Any recommendations

[@BadLuckGarage]

Yes, watch the video and pay attention to the part where I explain the different bolt patterns. 😉

[@shipmannorthcutt9226]

@@BadLuckGarage I must be missing something. My TC bolts are 9.5 inches and everything I’m looking at is bigger

[@BadLuckGarage]

@@shipmannorthcutt9226 I don’t know of any GM converter that uses a 9.5” bolt pattern so I’m not sure what you’ve got going on brother.

[@shipmannorthcutt9226]

@@BadLuckGarage I going to leave you a photo on you FB page. I’m sure I’m doing something wrong

[@JonOffgrid]

i have to get one form jegs for a 700r4 it didnt work out for my 700 r4

[@BadLuckGarage]

Thats because your 700r4 uses a 10.5" bolt circle as stated in the video

[@glenncivale6824]

Great video! I'm trying to remove a 6.7 Cummins from an Allison 1000 in a 2010 step van and replace the Allison with a 1988 GM350 gas engine. Can't find any info if the bolt pattern will match up or, will the Allison 1000 operate without pcm control. It has an electronic module in it. If anyone has input, I'd be really grateful,.

[@BadLuckGarage]

@@glenncivale6824 I don’t really know much about Allison transmissions pertaining to computer control. As for the bolt pattern, just measure it. There’s a link to a video showing you how to measure torque converter bolt circles in the video description.

Thank you I hope you’re doing well I have a problem I have a 2004 LS engine 5.3 that I bought in a junkyard I’m trying to swap into a Dodge dart everything’s in but when I try to install the starter Motor I’m having problems it’s making noise grinding noise no I have a two speed powerglide transmission and I took your advice and buying that flywheel what am I doing wrong I tried Spacing it out with shims nothing is working help please

[@MrZaner1]

Great information! Thanks for sharing

[@BadLuckGarage]

Thanks for popping in Zane!

[@Joshuathedestroyer1]

this video is a little older but my question is, will a stock th350 converter not fit the flex plate properly? is that the reason you have to upgrade?

[@BadLuckGarage]

Most stock th350 converters will have a 10.75” pattern.

[@Synthfidel]

Thank you!! Now let me ask a question. What flexplate to mount an old school 454 to a modern 4l80e?

[@BadLuckGarage]

The 4L80 actually came behind 454s in truck applications in the 90s so there’s no guesswork involved. Goto autozone and have them look up a chevy truck with a 7.4/4L80 combo and get your flexplate. 👍🏻

[@Synthfidel]

@Bad Luck Garage my ‘77 Nova thanks you!

[@sevaslee4865]

How About a ls gen 3 on to a old 77 th350 transmission

[@BadLuckGarage]

So I guess it’s safe to say you didn’t watch the video.

[@sevaslee4865]

Okay I guess it does fit LOL. But what about all the electrical and other stuff I read I need to add the kick down there anything else that would be a major role in the install

[@BadLuckGarage]

@@sevaslee4865 There are no electronics for a th350 unless using one with lockup. (Very rare and weak so I don’t generally recommend using it). If you want to use a kickdown cable then yes, you’ll need a bracket for it and a longer cable. But most people using a non-overdrive transmission in an LS swap are doing so strictly for racing purposes and just block the kickdown cable as shown in both my th350 shift kit install video and my th350 manual valve body install video. In any other instance I would recommend using a 4L60e or 4L80e instead.

[@StunnasTTV]

what about a 2008 6.0 gmc XL !
