Probably not going to like it because your customer wasnt fully informed, nor did you have the information to really give them. 6l80s have a myriad of issues that cause them to fail just as easy as the 4l60hd aka the 4l65e. When driving a high horsepower engine on the street and being afraid of it any shift is going to be terrifying. Fd ratio being the same, the only thing you actually did is put him through MORE terrifying shifts with the early gears being MORE torquey and likely to spin tires. Officially solving NONE of your customers actual problems besides .5mpg improvement.
Hes a scammer that knows nothing about cars. He is just a face man standing at the front desk out of his mind on multiple drugs falling over on his mechanics that need to stand him back upright while smiling at the customer the whole time.
I like almost everything I watch. I appreciate the effort, and unless the video-maker is contemptible or dumb, there is no reason not to like it. People act like the “like” button is actual money out of their own pocket. Selfish bass-turds, give a like if you watch at least 1/4 of a video and don’t h8te it.
6th gear in the 6L80E is 0.67:1, if I remember correctly. I figure it was a typo in the video. Also, the 6 speed won't change the cruise RPM much at all without a much taller rear end gear. The reason the 6 speed was a big deal is because it allowed tall rear ends for fuel economy to be paired with good performance because of the gear spread. 0.69 vs 0.67 is basically the same, so not much should've changed unless you guys also swapped the ring and pinion, which wasn't mentioned. Also also, I've been occasionally coming back to this channel to watch your ITB setup on the E92 dyno video since it came out. It's really nice to see you guys branching out.
0.67, same in my 545rfe in my Dakota. Noticed even with my moms 2019 Ram with the Hemi and the 8spd, same mph same RPM as me, ~2000rpm at 70mph. Think her final drive is a 3.21? mines a 3.55. Biggest difference would be tire size. She's on 20s with a 31" tire, I'm on 17s with a 27" tire
@@NXT_LVL If the RPM is about the same for the two vehicles, and you know your final drive is 3.55, the RAM’s would have to be 4.10 with that tire size you specified.
I know with the T56 and 3.42 is just below 2000rpm at 80mph. You must be sure that your engine can work below 2000rpm. Depending on your cam choice that might not be possible. That being said, the corvette can be challanging to gear. If you do the 12 bolt internals swap the lowest gear ratio you can get is 3.73 and I think you need a thin one at that (one that fits a 4 series posi). I have dealt with C3s - the real challenge is physically fitting the transmission in. The cross member is not adjustable and the floor is fiberglass (up to 1975). TH400 is stock on most of these applications, but the 4L80 was supposedly a tight fit.
You have to have a motor with extreme amount of low rpm torque from idle-3500rpm for a transmission like this. Not loads of high rpm 6000-7000 tire busting horsepower
The ZF 8-speeds from the BMW and Dodges goes into a lot of conversions now. Aftermarket TCUs make the conversation easier. The 8-speed comes with fast and crisp gearshifts instead of a slow automatics or even an old manual gearbox.
Explaining the axle ratio with the RPM and final drive ratio would really help bring the concept together for people. Show that an old axle ratio like 3.42: 1 can be replaced by 2.62:1 because of the low first gear and the better spread with 6 speeds. Subscribed!
Thanks for the breakdown, OJ. I have a C3, mostly stock 350 with the Turbo 400 trans. I have been thinking about doing as trans swap, mostly to reduce RPM on the highway. The way the car is currently configured, I was looking between the 700R4 or the 4L60E (since I have a 4L60E available. Debated on making the jump to the 6L80, but I think it wouldn't make sense for this car. Again, thanks for breaking things down and helping me take the 6L80 off the table!
4L60 is quite abit skinner. With the higher rpm and horsepower/lower torque of a 350 and simplicity of a controller and narrow cockpit it is probably the smarter choice over the 6L80. But the R700 can easily by customised to handle the higher rpm smallblock over the Ls3 and up motors and not need modification to the trans tunnel. Youll need to seriously up the lowend torque as much as you can of the sbc and drop the diff ratio and fabricate trans mount and tunnel. Plus your going to need an electronic third party aftermarket electronic controller and if your thinking about Ls swapping it one day you might as well buy the holley controller now.
Nice content. I like seeing OJ’s personality come out more than you see in other channels, and the subtle jokes in the dialog and the added imagery are great. I’m always impressed at the variety of makes and projects you take on. 👍🏻
_Another great informative, and entertaining video from FMU. And what better way to explain a 6-speed auto in an LS-swapped '69 Corvette Stingray. My exact sentiment was why the car had the LS swap but kept the old transmission set-up(then you noted the diagram of the LS engine and drivetrain package). Here's the greatest point about classic somewhat resto-modded cars, without a good mechanic shop, going down that rabbit hole can be cost prohibitive. Kudos to Mr. Mills and to the future of a nice early C3 Chevy Corvette._
Another note: the 6l80 from GM & the 6R80 from Ford are half-siblings in a sense that they're derived from the vaulted ZF 6HP26 featured in other foreign luxury automobiles.
Fun video. Had this debate when putting together my LS3 Roadmaster Wagon swap project (it’s all on the Internet Brands Auto Group YT channel). I really wanted to do the 6L80 Connect and Cruise, and for a while, it was actually cheaper than the 4L65e, but as a first time DIYer, my Chevy Performance dealer recommended the 4L65e bc it was easier to fit in the OEM Roadmaster trans tunnel. With 3.42 gears it hits 2300 RPM at 75mph on the highway, but I can still manage 28mpg if I back down to 60-65mph in 4500 lb wagon. The downshifts are a bit weird at times… you want to accelerate but suddenly you’re back in 1st at 5500 RPM… and I don’t like how it rushes to get to 4th gear (I still need a trans tune). And the supermatics make a weird buzzing sound Chevy says is normal. But it has some fun features where you can blip the throttle (almost like a rev match) and it’ll drop down a gear consistently. Overall it’s working well, but would recommend the 6L80 of folks can manage it. Cheers!
Very informative, I'm a believer in drive train performance. Best improvement for your vehicle is drive train, doesn't do anything to add power if you're trans isn't translated
Great timing. I haven't watched the video yet but wanted to comment. I have a 97 cobra I'm rebuilding right now, all forged and arp, should be good for 1000hp and I'll be aiming for 600-700. I have a t45 5 speed that won't be long for this world if I don't baby it. Always liked the t56 6 speed but never felt it would get me much. Hopefully this video will make it all clear!
I have a 6l90 is a suburban, it’s an impressive transmission. They have issues with the stock JMBX converters so if you have an 80/90 swap it cost you &5k + for a transmission job.
The C3 was such a sexy ride these upgrades are definitely in the correct path. I would guess the frame and suspension could benefit from a little massage. After seeing you on other channels you have the rep to make this a "GREAT" channel. Good luck and I'll be watching.
At Corvettes at Carlisle there are a couple companies who do chassis swaps for Corvettes . C1, C2, C3's . Allows you to use whatever engine and more modern suspension . It's not cheap even just the frame ready to accept your style of engine and modern Corvette suspension . I saw at least two owners who showed up with enclosed trailers and purchased complete rolling chassis including the drive line . The chassis came on what looked like orange wheeled donuts to roll. You supply your own wheel and tire combos . I think the bare chassis were over 20 grand close to 30 k . Talking to one chassis builder he said with complete driveline and his chassis with newer Corvette suspension he had about $120,000.000 in a 73 Corvette . Not including the body itself . So these swaps using the best and more modern suspension/ chassis and engine swaps get very pricy .
I never knew that more gears were so important until I switched from a truck with a 6 speed to a truck with a 10 speed but the same engine. It is quicker and feels as if it has more horsepower.
Great video O.J. I have a 1970 Chevelle that I have been thinking about doing some type of trans swap to. Thanks for making the video. I'm not far from your shop maybe I'll bring it over one day. Keep up the good work.
Hope to bring my 90 iroc-z to your shop for custom exhaust to clear heidts irs we have installed. Grew up in Naperville in the early 80s and haven’t been back since late 90s so would be nice to get this work done with your shop.
Yes , everyone support this channel please! I remember first time I seen OJ on Alex’s channel with the 400,000 miles M5 ! I could tell then OJ was very sharp. Thanks fmu
Haha, 0.07:1 6th. Now THAT is a proper overdrive. If you wound out 5th gear to 6,500 rpm somehow (probably already impossible but work with me), the shift to that 6th would drop RPMs to 535 (if the torque converter stays locked). Otherwise it would just stall against the converter and make copious amounts of heat.
It would probably spin the tires backwards like hitting curb straight on at 60mph. Flood the motor and hydrolock the pistons from turning after bending valves and/or pushrods or just break the rockers. Doh!
@sean smallblocks used to spin anywhere ups and to 10,000- 12,000 with hypertech pistons and worked rods along with a factory forged crank in the 70s. Guess you forgot at 80 years old. But they dont manufacture anything forged anymore now do they?
I imagine this has to be over 6,000 to do this swap, I could be wrong but everything is so expensive and the knowledge to do something like this is not cheap. Great video and have a happy new year.
Great video. Love the thoroughness and detail. Great presentation. Also, the ‘ask’ for likes, comments and subscribes is the best I’ve ever heard. It was sincere and heartfelt. Finally, I agree with another comment that the ratio of views to likes is off. It’s not hard folks- hit that like button!
I had a supercharged c5 with the 4 speed auto (4L60 built by RPM transmissions). I also ran a 3.42 gear set. Motor was basically a stock ls1 with heavy valve springs and a borla catback. No headers. That combo made 472 /444 at the wheel through that setup. The blower was a Vortec V3si. My only complaint was the gap in the ratios between 2 and 3 gear and between 3 and 4th. The car was a great from a dig to 80 mph. Then the torque had to pull the long gearing. That car would have benefited immensely by having some split ratios in between 2nd and third and third and fourth.
I own a 97 trans am with a 6 speed manual , and a 2003 c5 with 4 speed auto. Before I went 383 , my trans am regularly got 30 mpg on the highway. My mostly stock corvette still gets 31mpg when cruising at 70mph.
Rebuild torque converters for a living and 8 out of 10 6L80 converters have a failed lock-up clutch lining. I recommend reprogramming this transmission as soon as it is out of warranty to help prevent this problem.
Great video! Never really though about a newer auto. I’m always the manual swap guy. But, sometimes if you’re gonna daily a C3 Vette, maybe a modern auto isn’t a bad option. Looking forward to watching the rest of the videos!!
Ive driven both 6 an 8 speed gm trucks and its a huge difference in the butt dyno. I do like a 3 speed in my older truck with more power. It feels like its always in the right gear and doesnt hunt for gears.
FMU for the win, OJ getting more comfortable every video. Quality editing too. Dont give up, keep going it will be worth it. Educational and informative content.
Bravo for being able to competently making the unexpected modifications for this swap/ The muscle car community online LOVES LS swaps and you can read raves about them online all day,. HOWEVER,..real world reviews and info about using updated transmission for these beloved engines are few and far between.
I have a 2012 C6 Grand Sport 4LT with the A6 and it's a nice driver. ARH headers catless x pipe with Haltech 108 intake and tuned sounds good runs good great daily driver.
Thanks for entertaining me for 15 minutes....lol. No worries, I have been a fan since I saw you on Alex's channel. You will grow, just takes time in this space. Cheers
Great start OJ. Looking forward to continuing the channel content! Adding a comment regarding the use of the "green-screen" effect. Don't have your body shifting across it. Keep it stable/anchored to one spot...closer to the "books" in this case...and just maintain the space to the left as your picture-in-picture area. It will function better for the video.
Cool car. I just dropped a slightly modded LQ9 mated to 6L80 with a 2600 stall, all turning a 10.5 rearend in my o2 reg cab short bed. Should be interesting lol. I also put the thermostat bypass in the trans cooler.
I instruct on race tracks and we get drivers with older cars that have automatic transmissions in their cars show up. Most have overheating issues. A video on that or what they can do without spending tons might helps. New subscriber and saw your work on the exhaust for Alex LS Porsche. Very nice work and enjoy your skills and content!
If they don't already have one an external trans cooler would be a good and cheap place to start. And if the trans has a lock-up converter then a switch to keep the converter locked up under hard throttle would also help. Of course the trans and converter need to be strong enough to handle the abuse.
You guys do some awesome work, and have very informative and entertaining videos. This channel needs many more subscribers. By the way, I don't think your supposed to lift a transmission on to the bench like that.... 😂 🤣
Only about half the views are liking this video. Let's support this quality automotive channel and get the likes up 👍

I appreciate the acknowledgment of the difficulty, even the factory is having, in making these electronically sophisticated transmissions reliable
Nice to see a shop take on challenging work rather than just refusing to help.
You got that right!
Kudos to you and your team for this informative video! Now I have a more clear path on what I can do for my own C3. 🙂
Glad it was helpful!
I did a full reverse manual valve body with a 4200 stall and triple disc lockup converter. I’m very pleased!
to your 6L80? sounds fun!

Ive seen small blocks spun past 8k ... its 2024 not 1970
It would probably spin the tires backwards like hitting curb straight on at 60mph. Flood the motor and hydrolock the pistons from turning after bending valves and/or pushrods or just break the rockers. Doh!

Became a subscriber after I saw you on Legit Street Cars. Enjoy the info and the videos. Thanks for your time.
Love the channel and all of your knowledge! Thanks for keeping the content fresh and educational.
Enjoyed the video, but I understand that you are a business. I'm hoping that you have more of both in the future.
New to the channel and I'm enjoying the videos
Very informative, nice to see a comparison
Just the thought of an 8 speed in an older model muscle car seems pretty cool to me.
I had a supercharged c5 with the 4 speed auto (4L60 built by RPM transmissions). I also ran a 3.42 gear set. Motor was basically a stock ls1 with heavy valve springs and a borla catback. No headers. That combo made 472 /444 at the wheel through that setup. The blower was a Vortec V3si. My only complaint was the gap in the ratios between 2 and 3 gear and between 3 and 4th. The car was a great from a dig to 80 mph. Then the torque had to pull the long gearing. That car would have benefited immensely by having some split ratios in between 2nd and third and third and fourth.
Keep the videos coming, OJ.
I own a 97 trans am with a 6 speed manual , and a 2003 c5 with 4 speed auto. Before I went 383 , my trans am regularly got 30 mpg on the highway. My mostly stock corvette still gets 31mpg when cruising at 70mph.
Vettes have a weird combo of lightness and straightforward engineering that works out to good mpg.
You show very interesting content to me, all though i own no Corvette. Thx a lot.
Keep it up! Always like your content.
Rebuild torque converters for a living and 8 out of 10 6L80 converters have a failed lock-up clutch lining. I recommend reprogramming this transmission as soon as it is out of warranty to help prevent this problem.
The way he just MANHANDLED that transmission up onto the workbench!!!
U guys are one of my favorite channels thank you !!
Great video! Never really though about a newer auto. I’m always the manual swap guy. But, sometimes if you’re gonna daily a C3 Vette, maybe a modern auto isn’t a bad option. Looking forward to watching the rest of the videos!!
Good content and great work as always. On a unrelated note, I want some of your e39 M5 headers one day.
Ive driven both 6 an 8 speed gm trucks and its a huge difference in the butt dyno. I do like a 3 speed in my older truck with more power. It feels like its always in the right gear and doesnt hunt for gears.
Great video Good luck with the Channel. Love seeing content from IL.
FMU for the win, OJ getting more comfortable every video. Quality editing too. Dont give up, keep going it will be worth it. Educational and informative content.
This is great content about a topic that nobody else seems to be covering... Well done. 👏🏻
Watching from 'down under' Oz 🇦🇺
U guys are going places with this channel🤘
keep it going don't give up
great to see this knowledge transfer and discussion on drivetrain on non European vehicles. You guys cover a lot of ground. Cheers and much respect.
Bravo for being able to competently making the unexpected modifications for this swap/
The muscle car community online LOVES LS swaps and you can read raves about them online all day,.
HOWEVER,..real world reviews and info about using updated transmission for these beloved engines are few and far between.
Thanks for the video! I wish I lived closer so that you could service my vehicle. 👍

Thanks for entertaining me for 15 minutes....lol. No worries, I have been a fan since I saw you on Alex's channel. You will grow, just takes time in this space. Cheers
Superb video. I was just thinking prior to watching this what the new GM 10 speed tranny would be like in a C3.
Great vid OJ!
love the content you do with LSC! you guys do excellent work!
Much appreciated!
This guy really knows his shit
I love the channel! I look forward to every new video.
Love the ls3 swapped vette. My wife's favorite body lines.
I found you guys through Legit Street Cars. I've been really impressed with y'all's work on that channel. Looking forward to seeing more here!
Welcome aboard!
I’m planning on buying a 70-71 Corvette stingray and trying to collect as much info and ideas as possible
hopefully this video helped. if you need any consultation with that swap, we have services that can guide you!
I love your videos!
Brother, upgrading to modern technology under the skin is my jam, good on you, the 6spd is a great transmission.
I'm asking these exact questions looking at modernizing my OBS Suburban.
I really appreciate your videos OJ. I wish your shop was here, near where I live. Oh, and please thank Alex for introducing you to me.
I am very glad that I happened upon your channel through another channel. I love your content.
Glad you enjoy it!
Really enjoy the videos, very informative and learn quite a lot.
Keep up the great work
Great start OJ. Looking forward to continuing the channel content!
Adding a comment regarding the use of the "green-screen" effect. Don't have your body shifting across it. Keep it stable/anchored to one spot...closer to the "books" in this case...and just maintain the space to the left as your picture-in-picture area. It will function better for the video.
Thanks O J & FMU team for this well presented explanation about transmission swap.
Good stuff! A lot to consider, but I bet the owner loves the lower RPM at highway speeds.
Thanks for this video. I am planning a similar project! This is perfect timing!
Glad it was helpful!
I haven't seen OJ since his appearance in Legit StreetCars channel. Good content man!
Dexron VI is used in substitution of Dexron III for the people that didn't know
Thanks Oj, great shop. hope to bring you some work some day.
Please do!
Cool car. I just dropped a slightly modded LQ9 mated to 6L80 with a 2600 stall, all turning a 10.5 rearend in my o2 reg cab short bed. Should be interesting lol. I also put the thermostat bypass in the trans cooler.
I just completed an 8hp45 swap in my BMW z3. It brought the car into the 21st century.
That’s a thing people do? Would love to have seen what’s involved with that swap.
Great info, you shifted all over my 4l65E rebuild....time to go 6 speed!
Cost and a smaller size are the only legitimate pros for the 4L65 over the 6L80.
Nice dead lift intro! Great breakdown of the technical data. Keep it up!
I knew I wasn’t the only one to notice the 0.07:1 sixth gear ratio listed for the 6L80, but since you asked for comments, I figured I’d do my part. 😁
You were supposed to leave 5 comments if we got it wrong 😂.
Tremec 5 speed manual took care of it in my c3.
Video production getting better. Thanks OJ and team.
We got a long way to go before we are at a level we are happy with, but your support is allowing us to expend more time on it. Thanks for noticing.
I instruct on race tracks and we get drivers with older cars that have automatic transmissions in their cars show up. Most have overheating issues. A video on that or what they can do without spending tons might helps. New subscriber and saw your work on the exhaust for Alex LS Porsche. Very nice work and enjoy your skills and content!
If they don't already have one an external trans cooler would be a good and cheap place to start. And if the trans has a lock-up converter then a switch to keep the converter locked up under hard throttle would also help. Of course the trans and converter need to be strong enough to handle the abuse.
You guys do some awesome work, and have very informative and entertaining videos. This channel needs many more subscribers. By the way, I don't think your supposed to lift a transmission on to the bench like that.... 😂 🤣
Thank you for sharing this info!!
