Okay looks like your post got 23 thumbs up. For sure I will do a manual transmission. I was actually already planning on it. I'm swapping my 68 Camaro from an automatic to a manual. But I'm working on my e-book right now so it may be a while, hopefully this summer. I'm a manual guy and have been driving a manual transmission as my daily driver since I was 22

I'm perfectly happy with the TH400 in my '88 Chevy G30 work van. Bought it '94 as a former GTE fleet vehicle with 85,000 on the OD. The odometer broke at 93,000 so I decided to wait until the speedo cratered to replace the unit. That hasn't happened yet so think the original 5.7 and TH400 has around 300,000 of use with no breakdowns.
Turbo-Hydramatic 425 (TH425 or THM 425,[1] later 325) was an automatic transmission developed and produced by General Motors. The THM425 was a derivative of the THM400; most parts directly interchange and some others will interchange with minor modifications. The internal parts spin the opposite direction in the THM425; the helical angle of the planetary gears is "reversed" and the one-way clutches freewheel in the opposite direction, for example. The THM425 was developed for the 1966 Oldsmobile Toronado and the 1967 Cadillac Eldorado.
Yeah there were a lot of transmissions that I didn't cover, unfortunately just didn't have the time to do them all. I tried to cover the mainstream transmissions that most of my LS swapping viewers would enjoy
Those Transgo kits come in different types for various different transmissions. You can get them in stage 1/2 (quicker shifts, but still auto) or stage 3 which is stage 2 shifts with full manual shifting. Highly recommend
My 1955 Chevrolet 3600 had the Hydramatic 4 sp. ORIGINAL. 1st gear was what I would call a Granny .......in the owners manual it listed at full throttle it came out of 1st at between 5-7 mph. !
Also the THM350B, which at least Buick used in mid-sized cars with smallblock V8' from '71 to '73. Essentially a heavy duty THM350 with extra clutches. Then there was the TH350 with a lockup converter... Then the THM400 'Switch-Pitch", has a converter with 2 different stall speeds.
I had a 1993 Silverado with a 5.7 and 4L60E. The original trans lasted until 118,000 miles and lost 2nd gear, so i had it overhauled. That build lasted until 258,000 miles. Then it developed the notorious 1st to 2nd slam shift due to a worn check ball passage. I sold the trans to a Jeep builder at that point because the truck had bad salt cancer.
I had a similar experience and it was the best 93 z71 gmc I ever had. The engine, front end , axles and body were never touched for 258,000 miles. The frame rust eventually got too bad and had to be sold.
I had a "cast iron" case PowerGlide in a 57 Chevy with a 61 spec 283 FI. The only good advantage was the Iron case Powerglide, the bands could be adjusted externally without pulling the pan.
I had a 81 Chevy 1/2 ton pickup with a TH-350C. It had the lockup converter on it. I wired a switch to the vacumm relay that I could drive it around town with the TC unlocked. Otherwise it was constantly locking and unlocking around town in traffic
Yeah I had scripted it and had it ready to go but I totally forgot to record it. So I had to delete the video with 50,000 views and repost it. So painful.
There's no mention of GM's Roto-Hydramatic (Slim-Jim). This lightweight, aluminum-cased four-range, three-gear transmission was used in some Oldsmobile, Pontiac and Holden (Australian) models between 1961 and 1965. The larger Model 10 was used on full-sized cars whereas the lighter-weight Model 5 was used on intermediate and compact models, such as the 1961-63 Pontiac Tempest and Olds Cutlass/F-85/Jetfire. The 1962 Olds Jetfire with its Turbo-Rocket 215 V8 aluminum block engine coupled to the Model 5 transmission was the first turbocharged production car ever made.
The ONLY reason the OEM's spent the million to develop 8- and 10-speeds was to meet emissions and mileage rules - keep the engine in as narrow an rpm band as possible, then tune it to meet the regs. So the EPA drove up the cost of vehicles, PLUS the cost of repairs (go price a 10-speed rebuild). Compare that to the amount of fuel saved and reduced emissions, both of which are so small as to be insignificant.
One variation of the TH400 that often gets overlooked is the TH475, which was beefed up for use in heavier duty trucks and motor homes. They're unique among factory transmission offerings in that they use straight cut gears, which have a pronounced whine that is even louder than the famous Muncie M22.
Looking at this very good comprehensive video again , im thinking of the 1960s Super Turbine 300 or ST300 2 and a half speed auto , it came out in the late 1960s Oldsmobiles with drag pack , instead of using the torque Converter as a lock up , they used the hydraulic actuation to flip the converter blades in two different pitches ( some times called a swich pitch transmission) so you drove to the track at a normal 1000 rpm stall Torque Converter , flicked a swich in the car and the Torque Converter changed to 2200 stall , drag the car and flick the switch and drive home on normal 1000 rpm stall, it was in other GM cars . Also the T425 trans in front wheel drive Olds Toranados and Caddys , a strange transaxel that left the motor north south but drove the front wheels by sliding the trans under the side of the motor , running a chain from the end of the Torque Converter on the back of the motor to the trans facing to the front of the car, bolted on the front ( normally the back )of the trans was a 10 bolt diff with two half shafts , one running through the oil pan of the V8 to one wheel and out the other side to the other wheel ! And lastly the T475 heavy duty trans .
The manual mode was not limited to the 8 and 10 speed units. Not sure what year it was introduced, but the manual shift mode was also available on the 6L80/6L90. I know for sure they were in the trucks in 2017.
Decades ago GM had a TH600 as well but special order not normal on their own lineup of vehicles. From what I remember they were a 400 with extra clutches to run cooler and for heavy fleet use.
chrysler small block transmissions used the same bellhousing for 50 years, you can bolt a slant six to a viper transmission (ironically the dodge truck v10 is NOT the same bolt pattern), some of the newer engines kept using it too (some) the hemi and 4.7 and 3.7 and even the diesel crd from a jeep liberty can be directly bolted to any trans made in that 50 year period
Love your stuff. Just a heads up, New Naming 4L80E slide has the transverse and longitudinal, FWD and RWD backwards. Transverse is FWD Longitudinal is RWD. Keep up the good work though. Great stuff.
Interesting point about a powerglide before 1967 is that they also had a rear pump therefore could be used to push start the car if rolling 30-35 miles per hour. I know because I had a powerglide in a 1966 Impala.
You forgot the TH200.... no, not the TH200-4R. I don't know what internals may have been shared, but the 200 non-OD transmission was a thing. We had one behind a 1983 307 Olds.
Very interesting indeed! Thanks, that clears up a lot of confusion. The powerglide was great for neutral drops.... couldn't kill it. Whatever the Chevette had in it (probably a TH200)? could go 60 mph full throttle and then into reverse where it would skid to zero mph and then start kindly backing up. (video on my channel) Got a Vette original footage). Thanks again.
Funny thing is Powerglides and TH400 (2 or 3 speed configurations) for drag racing are everywhere... Mark Mickey's TH400 as got to be the most bad ass transmotion
You missed the TH200 intended for 6l and 305 2V engines. Ended up installed in 350 4V Impala and Caprice cars. Of course the increased vehicle weight and engine torque caused a bit of trouble, eventually repaired. Then they added the OD.
I'm an old car guy, I seen a 57 Chevy Belair at a car show with a Turboglide transmission, it was orginal low mileage car with the orginal transmission. It would be very interesting to me to know detail information on this transmission. Thanks!
You have most GM automatics except for the early Hydramatic ,one version being a 4 speed auto that came in some Canadian GMC trucks , I seen a 1957 with one of them behind a 283 2 barrel.
Yeah there are quite a few transmissions that were not on my list that were built for just a few years or in low volumes or are not really for performance applications. I try to focus mainly on V8 automatic transmissions which is where my viewers are with their builds
They might refer to the turbo 350 as a three speed powerglide. But it has enough differences that they don't do the same thing a powerglide does. Other than the obvious third gear. And that is the fact that the pump is driven by the input shaft instead of the output shaft. Which means that you can't push start a turbo 350 but you can with the powerglide.
@@concretesteelmsn I'm not sure i understand what your saying. The early cast iron and early aluminum cases I believe at least until 1964 had front and rear pumps. If you had a battery going bad place the tranny in neutral get the car going about 15 miles an hour and with the key in the on position you put the tranny in low and it would fire off and you were good to go. The power glide is a two speed two pump transmission. The turbo 350 has three gears and a single front pump leaving it and the following trannys not push startable. I've lost count of the times I've pushed started my 64 Impala. But I've never even attempted it on the turbo 200, 350,400 or the 4L80E and I'm not going down the rest of the list of automatics they have out now.
Thanks for the great information, and Really Thanks for the Ebook 👍 I wish there was info about the Hydramatics of the 50s, they were bad _ss, or the Dynaflows. Subscribed!
An interesting detail I noticed when debating a 10L vs 8L: for a tall tire, tall rear gear vehicle, there is no tangible difference. Not even when towing. The two extra gears are basically useless unless you're running a short tire and low gearing.
Yeah the car companies are so focused on fuel economy I think that's why you see the extra two gears with the 10 speed even though it's probably only 1 or 2% more efficient versus an eight speed
@AutoGuild it would have to be a ridiculously miniscule difference. Top gear is virtually identical, weight is virtually identical, and power loss is virtually identical. Like you said, if it's a MPG difference it will be 1-2% at best. On my pickup, that would be right at 2-4 tank fills per 100,000 miles. Pointless.
@@AutoGuild yea and I notice that the more auto gears they put the lower the gears are on the rear end ..I see 10 speed autos with a 2.77 rear ..trash !!!!
Early 90’s GM was not operating with the metric system like that, hell, the transmissions are still advertised in lb-ft first with nm in brackets behind it. I wish the 4L60 was rated for ~440 lol
I think another transmission missing is the TH200 from approximately 76 to 89. I believe the 1979 Caprice Classic with the 305 engine had this transmission. Failed after a few years and replaced it with a TH350.
As a diehard PONTIAC fan (with no General Motors politics to hold me back), u didn't mention the Super Turbine 300 two-speed transmission that came in the B.O.P. bolt pattern. I had one behind a 350 PONTIAC in a Le Mans. It's maybe a weaker trans than the powerglide but, i hope u include more B.O.P. & Cadillac transmissions in future videos. Thanks.
You missed the Turboglide ( I had one in my 1960 348 powered Impala convertible).It was a forerunner to the now popular continuously variable transmission designs. The one-forward-speed automatic with a torque converter was totally different from its two-forward-speed Powerglide sister. You also missed the 3 speed Hydra-matic that I had in My 1960 Oldsmobile Super 88 conv.Please update this so Your video is correct for the younger generations!
Th2004r went to 1990 and I'd like to see the Info on the th2004r ever being in a Corvette. Ive installed multiple 2004r's behind LS engines and work good. They can be built to hold over 700RWHP. Your info is funny.
5:05 weight is not the only downside of the 4L80, it has a much narrower gear spread. First is 2.48 compared to the 4L60’s 3.059 and it even has a shorter overdrive at 0.75 vs 0.696. There was a company making a wider first and second gear for an 80 but from what I’ve read they were weaker than stock. TCI developed a 6 speed version of the 4L80 with a 2.97 first gear. The 6L80 has a 4.03 first gear. Many things to consider.
@@samholdsworth420 but a consideration for lower powered vehicles, like 250-400 HP. To your point, though, super comp dragsters run in the 8s with two speed powerglides, so you don’t have to have 6 to 10 gears if you have 4 digit HP.
The added parasitic drag with the 4L80 is worse imo, most guys running >400hp are running 60/65/70’s over 80s anyways, but if they do have a 4L80 and need the power you can always shorten the rear end a bit
The PCS TCM-2650 allows the later model 6 speeds to be swapped behind earlier EFI & even carbed engines. It may also work with the 8 & 10 speeds, but I'm not sure on those.
Import driver, always love muscle but who can afford? Planning on a project hearse and it may be an automatic. Seems like rebuilding a trans would make a fun project itself. Thanks for the vid!
Great video. I have a low mileage 2001 LS Camaro in beautiful condition. It's Procharged and makes over 500/500 to the wheels. I'd like to make more but I'm pretty limited by the tranny. I don't really like the available options I'm aware of. I need at least 4 gears. So we start at the 4l60e(which it has now with some minimal upgrades). A built 4L60 gets really expensive, will still be in danger over 600whp or so, and honestly I'm not that big a fan of it. The 4L80 can be built to handle my power goals but it's darn near 100 pounds heavier, expensive, and doesn't excite me very much. Honestly after that I'm not really sure what goes into making a more modern tranny work in my application. Something like the 6l90 sounds ideal as it is modern and won't need to be built up a ton because it's already made to handle good power. But as I learned in your video the housing dimensions are big and they might have some reliability issues(?). I am at a loss what to do. I can't articulate why I don't like the 4Ls in performance applications but they just don't feel that fun or exciting to me(even with a high stall converter). I would rather not pour all my savings into something I won't be in love with but as of right now it's looking like my only realistic option. I would love to hear your thoughts and possibly a video. Over the many years TH-cam has existed I've only subscribed to 2 channels because I feel the yt algorithm does a good job bringing me to what I want to see and there is no reason for me to mess with success. However, I found this video very insightful and eagerly await more. You will now be my 3rd subscription ever. Great work.
Yeah sporty bill at 70-100lbs heavier 4L80 is hard to accept. Your car sounds super fun. Even a five speed would be ideal. I'm actually a hard-core manual transmission guy, so I'm converting my 68 Camaro into a manual, I think that's where the fun is! Thanks on the subscription. I'm actually subscribed to by think around 300 channels which is crazy but I watch mostly TH-cam in my free time I don't watch too much regular TV. I have a few other videos you may like if you want to check out the rest of my channel. Thanks for joining
@@xmo552 I appreciate your advice. In my cursory search it doesn't seem like it can handle much more power than a 4l60, nevermind a decent 4l80. Is there something I'm missing? Even the higher end built versions seem to be rated for like 475hp max and I'm already making that to the wheels with plans to go even further. Thanks for your help.
@@robertborgeson1821 I didn't look at their specs. I assumed they were currently handling more. You may have to give up extra gears. If you're open to that (or If you're forced to go that way) you could go to a Powerglide. In my case for a street truck/tow/hauler in an old truck. : I don't want to lose my th400. I don't want many electronics. I want/need an overdrive. I'm going with a Gear Vendors. It will give me overdrive in 3 gears. 1st, 1 OD, 2nd, 2 OD, 3rd, 3 OD. 6 forward gears. I keep my vehicle in the powerband without searching for gears. It can be automatic or manually done. A big benefit for me is I can tow in (.78) overdrive and the GVWR is 30k I think. In my truck the additional length is a non issue. Draw backs for me: 1) th400 is a non lockup. 2) th700-r4 OD is .70 3) th200-4r OD is .68 Another benefit is I keep my 4.56 in the back for launch and heavy loads. With GearVendor in high OD that now acts like a 3.55 rear gear for cruising. If I have to I can change that later if I want higher. 4l80 looked good but if I swapped in that trans I may as well do a full LS swap. The current plan is a TPI turbo. Plan B is Cummins. Check out the Gear Vendors site. They have units for many different transmissions. Maybe they have a possible combination you haven't considered. I already mentioned 2 GM muscle car transmissions. I know you probably won't want to adapt a Ford but..... C6, toploader, t56. T56 Chevy, Viper, Terminator. Lastly Mopar has great transmissions. The 426 Hemi 4 speed manual or the legendary 727 TorqueFlight. The 727 evolved into the 46re, 46rh, 47rh, 47re, 48re. The modern TorqueFlight Dodge transmissions don't have a great record behind a Cummins. Fix it with upgrades and you're golden. My long bed 4 door 4x4 dually Ram has a 48re with all the goodies. Besides the transmission... the truck is 100% stock. In my case stock is 325HP and 600TQ. Zero issues. It's a big trans for a Camaro, but maybe. Idk. Last idea would be a GM Allison. Again it's a big truck trans, but that may be your huckleberry.
@@robertborgeson1821 I think you answer will be found by playing with gear calculators and ultimately choosing an older trans like I did + GV. Look at the Tractor Pull and Truck Pull world. Those are brutal torque test. My buddy does that in the gasoline class. He whoops butt on the big blocks and even diesels and he's running a 355 SBC th350 combo. The staple is th400 or PG. The diesel classes are usually running their stock trans model but built to the hilt.
Great video 👍🏼however you said the 10 speed can not be swapped to a ls motor. That is not true. Powertrain swap solutions has a swap to swap a 10L80 to the 6.0 ls 6.2 ls motors.
You didn't mention the THM 200. I know everyone tries hard to forget that abortion, but they did exist and I am sure there are still some vehicles out there with one. Or maybe not, the TH200 to TH350 swap was a huge thing. Another thing about the TH350/400, there were two "TH375" transmissions, which were not the same. First was the TH375 which was essentially a TH400 with a TH350 sized and splined output shaft. Used extensively by Oldsmobile in their B cars (Delta 88, 98 Regency etc). Then, there was the TH375B, which was a beefed up TH350. Mostly found in some Buicks of the day, could be identified with a dual pattern bellhousing case that fit all BOP and Chevrolet V8 engines.
Yes, I was going to mention the 200 3 speed. They were high warrantee items, but the fact remains they are very popular in NHRA Stock class GM cars. Why? Because they are fast !
HP to price you really can’t do much better than a 4l80e and 6.0, find a clean used combo and a reliable 500+ crank hp for less than 5k is hard to beat. A healthy cam, 243/799 heads, a higher stall converter and a few transmission internals and you’re there.
Bad ass video ! Full of information. You can tell you did your homework..... Speaking of swapping transmissions,... A couple years ago , I swapped the stock 305/th350 in my 78 firebird, to a 355/700R4...... As far as size and position (relative to the stock engine location ) , would a 4L60E be a direct swap for my 700R4 ?
Somewhere there is a list of the lengths which is I believe is the deciding factor for a direct swap (other than electronic interface for shifting). YES, we need the author of the video to weigh in, please.
What about the LCT 1000/2000 series ? They lived behind the 8100 Vortec (496) in 2002-2006 GMT800 from class 2 to class 6, and of course, the Duramax. The 8 and 10 speeds are awful busy shifting units, and not to my liking, personally, but I would encourage anyone to install whatever _they_ want, in their build. Informative vid.
It’s funny, with all the transmissions, GM made, that the Powerglide is the most popular transmission at the drag strip. I even have one in my ‘67 Barracuda. 95% of the cars with American V8’s at the track, have ‘Glides.
Excellent educational video... I do have a question for you... and I have some trivia for you also. I am looking to swap out the power glide in my '63 Impala wagon for a Tremec 5 speed. I might consider an automatic, if I could get one to fit without much modification. I was told the Short shaft Turbo 400 was the same length as the Powerglide... if not, are they close. I do not want a TH350. The car has a 3.55 - 3.73 rear gear. I may do some toning with it. The engine is a minimum of 320 hp. Torque unknown at this time. Looking at a floor mounted shifter, regardless of trans used. Thanks! :)

There is also a fwd used in the mid 80s riviera, Toronado and Eldarado based on the 2004r trans. I believe it was referred to as the 325-4L
Also used in the GMC Motorhome (RV).

There's no mention of GM's Roto-Hydramatic (Slim-Jim). This lightweight, aluminum-cased four-range, three-gear transmission was used in some Oldsmobile, Pontiac and Holden (Australian) models between 1961 and 1965. The larger Model 10 was used on full-sized cars whereas the lighter-weight Model 5 was used on intermediate and compact models, such as the 1961-63 Pontiac Tempest and Olds Cutlass/F-85/Jetfire. The 1962 Olds Jetfire with its Turbo-Rocket 215 V8 aluminum block engine coupled to the Model 5 transmission was the first turbocharged production car ever made.
The less said about those, the better.
1:21 Chevy had one in the corvairs that you could push start, which is pretty unique for a auto.
Early aluminium powerglides could also be tow started . They had a rear pump as well as the normal front pump .
If a transmission has a rear pump in it, it can be push started
@@455buick6 they did stop doing that though.
Awesome video! The knowledge you’ve tracked down and shared with us is worth a like and subscribe!
The ONLY reason the OEM's spent the million to develop 8- and 10-speeds was to meet emissions and mileage rules - keep the engine in as narrow an rpm band as possible, then tune it to meet the regs.
So the EPA drove up the cost of vehicles, PLUS the cost of repairs (go price a 10-speed rebuild). Compare that to the amount of fuel saved and reduced emissions, both of which are so small as to be insignificant.
How many overdrives do they have, 2?
So true. It's also why trucks are so big now. The bigger and heavier they are, the more "wiggle" room they have for efficiency, or lack-there-of.
@@xmo552one...torque converter lock up
I liked my Ford 4EOD. Even after 300,000 miles it never slipped or skipped.
You must be .5 percent of owners. My co couldn't get 80 k miles.
This page is about GM.
Don't ruin our good time please. 😮
Thank you for this detail. I have been looking for this content for a long time.
The Power Glide My all time favorite. Raced one behind my Ford 4 cylinder. No torque converter necessary. Would work on the street too!!
Thanks for all your videos ! 🤙🏼
Your channel is number #1 for me !
One variation of the TH400 that often gets overlooked is the TH475, which was beefed up for use in heavier duty trucks and motor homes. They're unique among factory transmission offerings in that they use straight cut gears, which have a pronounced whine that is even louder than the famous Muncie M22.
Looking at this very good comprehensive video again , im thinking of the 1960s Super Turbine 300 or ST300 2 and a half speed auto , it came out in the late 1960s Oldsmobiles with drag pack , instead of using the torque Converter as a lock up , they used the hydraulic actuation to flip the converter blades in two different pitches ( some times called a swich pitch transmission) so you drove to the track at a normal 1000 rpm stall Torque Converter , flicked a swich in the car and the Torque Converter changed to 2200 stall , drag the car and flick the switch and drive home on normal 1000 rpm stall, it was in other GM cars . Also the T425 trans in front wheel drive Olds Toranados and Caddys , a strange transaxel that left the motor north south but drove the front wheels by sliding the trans under the side of the motor , running a chain from the end of the Torque Converter on the back of the motor to the trans facing to the front of the car, bolted on the front ( normally the back )of the trans was a 10 bolt diff with two half shafts , one running through the oil pan of the V8 to one wheel and out the other side to the other wheel ! And lastly the T475 heavy duty trans .
loved the flow chart
The manual mode was not limited to the 8 and 10 speed units. Not sure what year it was introduced, but the manual shift mode was also available on the 6L80/6L90. I know for sure they were in the trucks in 2017.
I have the 6L80 in an 09 G8 and it has manual shift mode. Have also driven early 2010s vans with the 6L90 and they too had manual shift.
The 4T65 in the 04+ Pontiacs like the Grand Prix GTP Comp G had Tapshift.
Decades ago GM had a TH600 as well but special order not normal on their own lineup of vehicles. From what I remember they were a 400 with extra clutches to run cooler and for heavy fleet use.
Just saw this fir the first time. See the e book is out already 😢. Great video brother. Looking forward to more content
chrysler small block transmissions used the same bellhousing for 50 years, you can bolt a slant six to a viper transmission (ironically the dodge truck v10 is NOT the same bolt pattern), some of the newer engines kept using it too (some) the hemi and 4.7 and 3.7 and even the diesel crd from a jeep liberty can be directly bolted to any trans made in that 50 year period
I think the 6 cyl bolt pattern was different. The starter slot was located on top rather than at the bottom.
Use the converter with the correct balance weight for the engine you have.
Love your stuff. Just a heads up, New Naming 4L80E slide has the transverse and longitudinal, FWD and RWD backwards. Transverse is FWD Longitudinal is RWD. Keep up the good work though. Great stuff.
so informative. barely diving into the GM modding stuff with my Yukon and theres so many choices
Interesting point about a powerglide before 1967 is that they also had a rear pump therefore could be used to push start the car if rolling 30-35 miles per hour. I know because I had a powerglide in a 1966 Impala.
Manual shift buttons have been around a lot longer. My old 2004 Grand Prix Comp G with the 4T65 had them.
You forgot the TH200.... no, not the TH200-4R. I don't know what internals may have been shared, but the 200 non-OD transmission was a thing. We had one behind a 1983 307 Olds.
U r an organizing expert!
Thanks 4 the great videos and books. I don't know how I didn't find u years ago !😊
Daryl in Fl.
Thank you I ordered the downloads and appreciate your hard work!
Very interesting indeed! Thanks, that clears up a lot of confusion. The powerglide was great for neutral drops.... couldn't kill it. Whatever the Chevette had in it (probably a TH200)? could go 60 mph full throttle and then into reverse where it would skid to zero mph and then start kindly backing up. (video on my channel) Got a Vette original footage). Thanks again.
I greatly appreciate the time you put in to these videos
Funny thing is Powerglides and TH400 (2 or 3 speed configurations) for drag racing are everywhere... Mark Mickey's TH400 as got to be the most bad ass transmotion
Precision Transmission on TH-cam has some great videos on rebuilding 4L60E transmissions so that they can handle more power.
Just do yourself a favor and upgrade to a 4l80 lol
Darn, I must have missed out on the pre-sale. Good video. Subscribed
You missed the TH200 intended for 6l and 305 2V engines. Ended up installed in 350 4V Impala and Caprice cars. Of course the increased vehicle weight and engine torque caused a bit of trouble, eventually repaired. Then they added the OD.
beautifully done, amazing information, thank you brother keep it up! dope video and graph!!!
Great information!
I am looking to swap the TH400 for an overdrive trans on my 71 Oldsmobile 455. Very helpful!!
Th400 doesn't torque converter lock up ?!
The 4L85-E Also I believe had Strait cut first gears.
I'm an old car guy, I seen a 57 Chevy Belair at a car show with a Turboglide transmission, it was orginal low mileage car with the orginal transmission. It would be very interesting to me to know detail information on this transmission. Thanks!
I had a 1961 Pontiac Bonneville Bubble back with a 4 speed automatic transmission, you missed that one !
Wow. Nice video. Consider making eBooks regarding the powertrian: differentials, suspension (such as FE6), stabilitrak... etc.
Great video, I think you overlooked the 200C and the Superturbine 300/Jetaway transmissions.
Great video as usual. Wishing you well on your channel. Need to get you up to 100K.
Would love to get there by the end of the year, 100,000 viewers. Thanks for the comment
You have most GM automatics except for the early Hydramatic ,one version being a 4 speed auto that came in some Canadian GMC trucks , I seen a 1957 with one of them behind a 283 2 barrel.
Yeah there are quite a few transmissions that were not on my list that were built for just a few years or in low volumes or are not really for performance applications. I try to focus mainly on V8 automatic transmissions which is where my viewers are with their builds
So the 1993 and 1994 model years of 4L60E transmissions used different electronic internals than all other 4L60Es in the following years. Just FYI
They might refer to the turbo 350 as a three speed powerglide. But it has enough differences that they don't do the same thing a powerglide does. Other than the obvious third gear. And that is the fact that the pump is driven by the input shaft instead of the output shaft. Which means that you can't push start a turbo 350 but you can with the powerglide.
you got that wrong it is the other way around
@@concretesteelmsn I'm not sure i understand what your saying. The early cast iron and early aluminum cases I believe at least until 1964 had front and rear pumps. If you had a battery going bad place the tranny in neutral get the car going about 15 miles an hour and with the key in the on position you put the tranny in low and it would fire off and you were good to go. The power glide is a two speed two pump transmission. The turbo 350 has three gears and a single front pump leaving it and the following trannys not push startable. I've lost count of the times I've pushed started my 64 Impala. But I've never even attempted it on the turbo 200, 350,400 or the 4L80E and I'm not going down the rest of the list of automatics they have out now.
The powerglides with a rear pump also had a front pump and it was only the early powerglides that had the rear pump .
We used to pull start my 63 Impala and my 66 Chevelle, both had 2 speed Power glide trannies with 283 V8's.
I run the 4L60 in my '71 F250 4x4. Love it....
Why?! Lol
4Lslippy for the loss.
Thanks for the great information, and Really Thanks for the Ebook 👍 I wish there was info about the Hydramatics of the 50s, they were bad _ss, or the Dynaflows. Subscribed!
Forgot the th375, had one in a 67 impala
An interesting detail I noticed when debating a 10L vs 8L: for a tall tire, tall rear gear vehicle, there is no tangible difference. Not even when towing. The two extra gears are basically useless unless you're running a short tire and low gearing.
Yeah the car companies are so focused on fuel economy I think that's why you see the extra two gears with the 10 speed even though it's probably only 1 or 2% more efficient versus an eight speed
@AutoGuild it would have to be a ridiculously miniscule difference. Top gear is virtually identical, weight is virtually identical, and power loss is virtually identical. Like you said, if it's a MPG difference it will be 1-2% at best. On my pickup, that would be right at 2-4 tank fills per 100,000 miles. Pointless.
@@AutoGuild yea and I notice that the more auto gears they put the lower the gears are on the rear end ..I see 10 speed autos with a 2.77 rear ..trash !!!!
Not to mention it skips gears if it doesn't need em
I always was under the impression that The “80” is for 800NM which equates to 590 Ft/lbs… 60 was for 600nm or 442ft/lbs which seems accurate lol
Early 90’s GM was not operating with the metric system like that, hell, the transmissions are still advertised in lb-ft first with nm in brackets behind it. I wish the 4L60 was rated for ~440 lol
I think another transmission missing is the TH200 from approximately 76 to 89. I believe the 1979 Caprice Classic with the 305 engine had this transmission. Failed after a few years and replaced it with a TH350.
You should have fun delving into the TH-180/3L30 that became the 4L30E.
How about the hydromantic in the 50's Oldsmobile's and Cadillac. I believe here were some prewar also.
and tanks with the cad flathead v8
Please do a video on the T series front wheel drive transmissions from GM thank you for the knowledge!!!!
As a diehard PONTIAC fan (with no General Motors politics to hold me back), u didn't mention the Super Turbine 300 two-speed transmission that came in the B.O.P. bolt pattern. I had one behind a 350 PONTIAC in a Le Mans. It's maybe a weaker trans than the powerglide but, i hope u include more B.O.P. & Cadillac transmissions in future videos. Thanks.
not weaker it had a switch pitch stator good trans
A video like this one but on Ford's automatics would be amazing. I know you are more of a chevy channel, but it would still be very cool!
FERD
You missed the Turboglide ( I had one in my 1960 348 powered Impala convertible).It was a forerunner to the now popular continuously variable transmission designs. The one-forward-speed automatic with a torque converter was totally different from its two-forward-speed Powerglide sister. You also missed the 3 speed Hydra-matic that I had in My 1960 Oldsmobile Super 88 conv.Please update this so Your video is correct for the younger generations!
There was also the 6L45 which appeared in a few Cadillac and BMW models.
Th2004r went to 1990 and I'd like to see the Info on the th2004r ever being in a Corvette. Ive installed multiple 2004r's behind LS engines and work good. They can be built to hold over 700RWHP. Your info is funny.
5:05 weight is not the only downside of the 4L80, it has a much narrower gear spread. First is 2.48 compared to the 4L60’s 3.059 and it even has a shorter overdrive at 0.75 vs 0.696. There was a company making a wider first and second gear for an 80 but from what I’ve read they were weaker than stock. TCI developed a 6 speed version of the 4L80 with a 2.97 first gear. The 6L80 has a 4.03 first gear. Many things to consider.
Taller first because its typically behind more powerful engines. 😊
@@samholdsworth420 but a consideration for lower powered vehicles, like 250-400 HP. To your point, though, super comp dragsters run in the 8s with two speed powerglides, so you don’t have to have 6 to 10 gears if you have 4 digit HP.
@@snappyaj9053 I only favor the 4L80 because I got tired of helping my friend swap a 4l60e in his Silverado...
The added parasitic drag with the 4L80 is worse imo, most guys running >400hp are running 60/65/70’s over 80s anyways, but if they do have a 4L80 and need the power you can always shorten the rear end a bit
I will take a properly prepped TH200 4R over anything on the list. Better gear ratio combos than the other 4sp OD units.
you forgot the TH375.which was used in the erly to mid 70's, and then again in the 90's.
this content is so specific and im glad i found it
Great video, but I noticed at about the 8:00 mark you have fwd and rwd drive reversed on your pics.
Yeah, that's kind of a big deal when the topic is centered around GM's longitudinally-mounted transmissions.
I know 5 people whose Chevy truck transmission went out at 100-150k miles last year, mechanics said their pumps are garbage.
Owned a colorado with a 4L60e, can confirm they are one of the slowest slushboxes available
You left out the ST-300 and Th-300 2 -speed's, had the same 1:72 & 1:1ration's as Powerglide but BOP bellhousing.
Good video but the 81 corvette did not get 200-r4. It came with a TH350C.
The PCS TCM-2650 allows the later model 6 speeds to be swapped behind earlier EFI & even carbed engines. It may also work with the 8 & 10 speeds, but I'm not sure on those.
3:25 Please tell me when was a 700r4 was put behind a 454?
Yes I believe that is a mistake on my part.
You missed all the 50’s dyna flow Buick, and Oldsmobile transmissions. As well as the early Cadillac models.
I know I'm sorry for not covering the BOP transmissions. The video would have been too long!
that deserves its own separate video
Didn't mention the most overrated transmission of all time either: the Allisons used in 3/4 ton and up trucks.
The 200 r4 would fit Chevy, or BOP. I used a 700R4 with my Oldsmobile motor and used a TCI conversion plate to use it.
I will wait and pay for it. Your information is valuable.
The 5l40 and 5l50 were also used in the BMW E46 3 series
You forgot to mention of manual shifter buttons for the 6L90 used in some models like the CTSV V2.
Great video but… You seem to have missed one. Ready? The early 60’s Turbo-Glide, yep. Almost seems like it kinda resembled a CVT, but fluid coupled.

Dang, The things that go by in the decades that fly by!
Import driver, always love muscle but who can afford? Planning on a project hearse and it may be an automatic. Seems like rebuilding a trans would make a fun project itself. Thanks for the vid!
Great video. I have a low mileage 2001 LS Camaro in beautiful condition. It's Procharged and makes over 500/500 to the wheels. I'd like to make more but I'm pretty limited by the tranny. I don't really like the available options I'm aware of. I need at least 4 gears. So we start at the 4l60e(which it has now with some minimal upgrades). A built 4L60 gets really expensive, will still be in danger over 600whp or so, and honestly I'm not that big a fan of it. The 4L80 can be built to handle my power goals but it's darn near 100 pounds heavier, expensive, and doesn't excite me very much. Honestly after that I'm not really sure what goes into making a more modern tranny work in my application. Something like the 6l90 sounds ideal as it is modern and won't need to be built up a ton because it's already made to handle good power. But as I learned in your video the housing dimensions are big and they might have some reliability issues(?). I am at a loss what to do. I can't articulate why I don't like the 4Ls in performance applications but they just don't feel that fun or exciting to me(even with a high stall converter). I would rather not pour all my savings into something I won't be in love with but as of right now it's looking like my only realistic option. I would love to hear your thoughts and possibly a video. Over the many years TH-cam has existed I've only subscribed to 2 channels because I feel the yt algorithm does a good job bringing me to what I want to see and there is no reason for me to mess with success. However, I found this video very insightful and eagerly await more. You will now be my 3rd subscription ever. Great work.
Yeah sporty bill at 70-100lbs heavier 4L80 is hard to accept. Your car sounds super fun. Even a five speed would be ideal. I'm actually a hard-core manual transmission guy, so I'm converting my 68 Camaro into a manual, I think that's where the fun is! Thanks on the subscription. I'm actually subscribed to by think around 300 channels which is crazy but I watch mostly TH-cam in my free time I don't watch too much regular TV. I have a few other videos you may like if you want to check out the rest of my channel. Thanks for joining
Borgeson, look at a th200-4r
@@xmo552 I appreciate your advice. In my cursory search it doesn't seem like it can handle much more power than a 4l60, nevermind a decent 4l80. Is there something I'm missing? Even the higher end built versions seem to be rated for like 475hp max and I'm already making that to the wheels with plans to go even further. Thanks for your help.
@@robertborgeson1821
I didn't look at their specs. I assumed they were currently handling more.
You may have to give up extra gears. If you're open to that (or If you're forced to go that way) you could go to a Powerglide.
In my case for a street truck/tow/hauler in an old truck. :
I don't want to lose my th400.
I don't want many electronics.
I want/need an overdrive.
I'm going with a Gear Vendors.
It will give me overdrive in 3 gears.
1st, 1 OD, 2nd, 2 OD, 3rd, 3 OD.
6 forward gears.
I keep my vehicle in the powerband without searching for gears. It can be automatic or manually done.
A big benefit for me is I can tow in
(.78) overdrive and the GVWR is 30k I think. In my truck the additional length is a non issue.
Draw backs for me:
1) th400 is a non lockup.
2) th700-r4 OD is .70
3) th200-4r OD is .68
Another benefit is I keep my 4.56 in the back for launch and heavy loads. With GearVendor in high OD that now acts like a 3.55 rear gear for cruising. If I have to I can change that later if I want higher.
4l80 looked good but if I swapped in that trans I may as well do a full LS swap. The current plan is a TPI turbo. Plan B is Cummins.
Check out the Gear Vendors site. They have units for many different transmissions. Maybe they have a possible combination you haven't considered.
I already mentioned 2 GM muscle car transmissions. I know you probably won't want to adapt a Ford but..... C6, toploader, t56.
T56 Chevy, Viper, Terminator.
Lastly Mopar has great transmissions. The 426 Hemi 4 speed manual or the legendary 727 TorqueFlight. The 727 evolved into the 46re, 46rh, 47rh, 47re, 48re.
The modern TorqueFlight Dodge transmissions don't have a great record behind a Cummins. Fix it with upgrades and you're golden. My long bed 4 door 4x4 dually Ram has a 48re with all the goodies. Besides the transmission... the truck is 100% stock. In my case stock is 325HP and 600TQ. Zero issues.
It's a big trans for a Camaro, but maybe. Idk.
Last idea would be a GM Allison. Again it's a big truck trans, but that may be your huckleberry.
@@robertborgeson1821
I think you answer will be found by playing with gear calculators and ultimately choosing an older trans like I did + GV.
Look at the Tractor Pull and Truck Pull world. Those are brutal torque test. My buddy does that in the gasoline class. He whoops butt on the big blocks and even diesels and he's running a 355 SBC th350 combo.
The staple is th400 or PG.
The diesel classes are usually running their stock trans model but built to the hilt.
Great video 👍🏼however you said the 10 speed can not be swapped to a ls motor. That is not true. Powertrain swap solutions has a swap to swap a 10L80 to the 6.0 ls 6.2 ls motors.
When will the LS swap e book be released? Thanks for the great content.
You didn't mention the THM 200. I know everyone tries hard to forget that abortion, but they did exist and I am sure there are still some vehicles out there with one. Or maybe not, the TH200 to TH350 swap was a huge thing. Another thing about the TH350/400, there were two "TH375" transmissions, which were not the same. First was the TH375 which was essentially a TH400 with a TH350 sized and splined output shaft. Used extensively by Oldsmobile in their B cars (Delta 88, 98 Regency etc). Then, there was the TH375B, which was a beefed up TH350. Mostly found in some Buicks of the day, could be identified with a dual pattern bellhousing case that fit all BOP and Chevrolet V8 engines.
I’ve rebuilt that hunk of junk.🤣🤣🤣
Yes, I was going to mention the 200 3 speed. They were high warrantee items, but the fact remains they are very popular in NHRA Stock class GM cars. Why? Because they are fast !
4l80 with the 6.o is the way to go
HP to price you really can’t do much better than a 4l80e and 6.0, find a clean used combo and a reliable 500+ crank hp for less than 5k is hard to beat.
A healthy cam, 243/799 heads, a higher stall converter and a few transmission internals and you’re there.
Thank you for the Videos !!!! my project daily driver, 2005 2500hd 6.0 4L80E....
Bad ass video ! Full of information. You can tell you did your homework.....
Speaking of swapping transmissions,... A couple years ago , I swapped the stock 305/th350 in my 78 firebird, to a 355/700R4...... As far as size and position (relative to the stock engine location ) , would a 4L60E be a direct swap for my 700R4 ?
Somewhere there is a list of the lengths which is I believe is the deciding factor for a direct swap (other than electronic interface for shifting). YES, we need the author of the video to weigh in, please.
Yes but 4L60E is electronic. You would want a 4L60 no E.
Go to Google and search this: 700R4 To 4L60E Transmission Swap On A 1989 Pontiac Trans Am - Electronic Overload
Search this on google: 700R4 To 4L60E Transmission Swap On A 1989 Pontiac Trans Am - Electronic Overload
What about the LCT 1000/2000 series ? They lived behind the 8100 Vortec (496) in 2002-2006 GMT800 from class 2 to class 6, and of course, the Duramax.
The 8 and 10 speeds are awful busy shifting units, and not to my liking, personally, but I would encourage anyone to install whatever _they_ want, in their build. Informative vid.
Yeah I didn't cover the heavy-duty transmission stuff. My channel is mostly focused around LS engine swaps and performance cars
It’s funny, with all the transmissions, GM made, that the Powerglide is the most popular transmission at the drag strip. I even have one in my ‘67 Barracuda. 95% of the cars with American V8’s at the track, have ‘Glides.
Excellent educational video... I do have a question for you... and I have some trivia for you also. I am looking to swap out the power glide in my '63 Impala wagon for a Tremec 5 speed. I might consider an automatic, if I could get one to fit without much modification. I was told the Short shaft Turbo 400 was the same length as the Powerglide... if not, are they close. I do not want a TH350. The car has a 3.55 - 3.73 rear gear. I may do some toning with it. The engine is a minimum of 320 hp. Torque unknown at this time. Looking at a floor mounted shifter, regardless of trans used. Thanks! :)
73 Monte Carlo I love that transmission I should have kept that
you have RWD labeled as Transverse... you have the descriptions backwards. Transverse is FWD and Longitudinal is RWD
You saw that also. I was wondering if it was an honest mistake or intentional to get comments.
