All 15 Automatic Transmissions (Powerglide to 10L90)

Brother can you do one on GM manual transmissions please ? They are iconic too man 😬🫣

[@AutoGuild]

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

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.

[@zacharymorris9917]

The first time I saw a "TH400" in a front wheel drive car I was blown away.

[@mattrodgers4878]

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

[@ronreyes9910]

Also used in the GMC Motorhome (RV).

[@AutoGuild]

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

The 200r4 was never in the corvette. The th350 with a lock up converter was used in 81. The 4L85E also had straight cut planetary gears for strength.

[@brucegillies1694]

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. !

[@ujmrider]

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.

[@hugieflhr03]

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.

[@deltacx1059]

1:21 Chevy had one in the corvairs that you could push start, which is pretty unique for a auto.

[@petercraig806]

Early aluminium powerglides could also be tow started . They had a rear pump as well as the normal front pump .

[@billwilson-es5yn]

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.

[@jamyers1971]

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.

[@xmo552]

How many overdrives do they have, 2?

[@dan1906]

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.

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.

[@StephenViola-ib8dq]

They had no pan on cast Iron Glide.

[@jamyers1971]

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.

[@HansBelphegor]

My 81 camaro had the locking one

[@leskeegan9033]

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

[@crionics99]

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

[@theEVILone0130]

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]

you got that wrong it is the other way around

[@theEVILone0130]

@@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.

[@petercraig806]

The powerglides with a rear pump also had a front pump and it was only the early powerglides that had the rear pump .

[@user-tb9rw7dh2t]

We used to pull start my 63 Impala and my 66 Chevelle, both had 2 speed Power glide trannies with 283 V8's.

[@FordGTmaniac]

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.

[@1979royalknight]

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.

[@knucklesskinner253]

this content is so specific and im glad i found it

[@zone47]

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.

[@snappyaj9053]

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.

[@T0mmyTune]

The Power Glide My all time favorite. Raced one behind my Ford 4 cylinder. No torque converter necessary. Would work on the street too!!

[@paulasturi4199]

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.

[@zacharymorris9917]

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.

[@AutoGuild]

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

[@zacharymorris9917]

@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.

[@1965bruiser]

@@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 !!!!

This is nice, but you seem to be missing a lot. This mostly seems to be a list for Chevrolet (and a couple Cadillacs) and not GM as a whole, while also omitting all of the FWD transmissions that were used with V8s too. 1.

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 KZbin 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.

@@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.

[@xmo552]

@@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.

Would have been nice if you mentioned about the 2-speed jet-a-way transmission with the switch pitch tork convertor as well ss the the switch pitch 400 turbo found in the Oldsmobile, Buick, & Cadillac's only that had and external switch to adjust the RPM stall of the tork converter ...they were the best transmission's set up you can take a small block 2-speed jet-a-way transmission switch pitch tork converter and swap it out i to the 400 turbo that would allow for a higher stall speed and put a switch on the shifter to manually control the stall of the conveter when I set (power) the switch in the up position I'm in high stall, when I turn tge switch down (power) the low stall direct drive on the converter great for drsg racing without buying expensive high stall tork converter just go to the wreckers snd look through the Buick / Olds section for the small block 2-speed and big block 400 these transmissions looked exactly the same as the chevy transmission's only difference was the switch on the left side the convertor and pump assembly to handle the extra tork from the Buick & Oldsmobile's

[@xmo552]

Yup

[@darylmorse]

Great video. Thanks for sharing your research!

[@racekar80]

You missed all the 50’s dyna flow Buick, and Oldsmobile transmissions. As well as the early Cadillac models.

[@AutoGuild]

I know I'm sorry for not covering the BOP transmissions. The video would have been too long!

[@shootermcgavin2819]

that deserves its own separate video

[@wyattlewis8671]

Didn't mention the most overrated transmission of all time either: the Allisons used in 3/4 ton and up trucks.

[@m3rdpwr]

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.

[@joshuadavis6094]

Forgot one very important ( due to lawsuits and failures) automatic transmission used on full size V8 GM cars equipped with the 305 and diesel 350... The infamous GM TH200 metric 3 speed transmission that eventually became the 4 speed TH200R4 that was used in the Grand national... But by then was a much better and stronger transmission than it's 3 speed metric counterpart... Also the TH250 as well... But I'm not as well versed on that one... Then you had the TH350

[@AlienMonkeyDXB]

You forgot to mention of manual shifter buttons for the 6L90 used in some models like the CTSV V2.

[@KevinVarga2002]

Thanks for all the info! Great video

[@73SDR]

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.

[@jamesgeorge4874]

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.

[@AutoGuild]

Yeah I didn't cover the heavy-duty transmission stuff. My channel is mostly focused around LS engine swaps and performance cars

[@1411MEDIA]

The 5l40 and 5l50 were also used in the BMW E46 3 series

[@DavidB7474]

Not sure I agree with the statement about the 700r4 around 3:30. The 700r4 I don’t think was ever used behind any 454 or in any 2500/3500 series truck. Square body trucks 2500/3500 series got th400 transmissions, then the 1991, still a square body style 3500 series trucks got the 4L80e. Prior to 1991 all dually trucks were th400 trucks. The new body style in 1988 didn’t offer the 454 with the 700r4 either. The only c1500 in the 1988 and up body style to get the 4L80e was the 1991-1993 454SS trucks. Regular 1988-1995 C1500 trucks didn’t get the 4L80e. 2500/3500 1988-1995 trucks got the 4l80e.

[@marksmigle7967]

FYI The cast iron powerglide was used in my 62 with the blue flame 6 cyl.

[@andertonforza]

Great video, but I noticed at about the 8:00 mark you have fwd and rwd drive reversed on your pics.

[@dadgarage7966]

Yeah, that's kind of a big deal when the topic is centered around GM's longitudinally-mounted transmissions.

[@PotatoeJoe69]

If I am going automatic, give me a Torqueflite 727. Absolute beast of a transmission..

[@9greatdanes981]

I know 5 people whose Chevy truck transmission went out at 100-150k miles last year, mechanics said their pumps are garbage.

[@youtubecarspottersguide1]

forgot the turbo glide 1958-61

[@itsmeagainmargret]

A couple to add to the list 4L75 and Allison 5,6 and 10 speed. The 5 speed Allison could be had behind the 8.1L BBC. the 6 and 10 were Duramax.

[@hughjass7025]

I will take a properly prepped TH200 4R over anything on the list. Better gear ratio combos than the other 4sp OD units.

[@VietyF]

I wish someone made a video exactly like this but for Toyota/Lexus, especially for their Aisin 8 speed direct sport shift in the IS F

[@mikehiers4819]

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.

[@mikehiers4819]

Turboglide link en.m.wikipedia.org/wiki/Turboglide

[@pmotorsports8276]

​@@mikehiers4819dynoflo also

[@pmotorsports8276]

Dyno flow also

[@mikehiers4819]

Dang, The things that go by in the decades that fly by!

[@jamesglavich1426]

I don't think that a factory 700-R4 would stand very many full throttle shifts behind even a mild HP 454 engine. I don't think GM ever offered this combo, for obvious reasons, but that being said, if you could get it to hook, it would have a great launch with the Deep 1st gear the 700-R4 had.

[@dadgarage7966]

You're right, GM didn't offer anything other than TH400s or its later variants bolted to big blocks. GM did put TH400s in C3 Corvettes but that was likely because of tight packaging (the electronic kick-down switch saved space).

[@FatCat715]

You should do more contect on Hemi engines and Chrysler transmissions.

[@james10739]

There is so much aftermarket stuff that could be covered like i remember a 5 and 6 speed 4l80e option but im not sure anyone is even making it still because a 6l90 probably makes more sense

[@NorthernChev]

You have the 5L40 as being introduced in 2003-04, yet my 2002 BMW 330xi, which has a build date of 2001, has the GM 5L40 in it.

[@THEFERMANATOR]

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.
