Yea totally missed that I said a glide had a 1.48 first gear. My bad I meant 1.80 or 1.76 for those who are extremely specific

Very good video and information. Always thought a power glide, was better for 1/8 mile racing and th400 was better for 1/4 mile. But after this video, I see the power glide is better for higher horsepower engines. While the Th400 extra gear helps out lower horsepower engines.

You are the only channel that is consistent with the videos love what you put out bro keep it up

I have been so torn on which trans I’m going to run. This video definitely helps break it down bro. Thanks!!

Awesome video as always, straight to the point and easy to understand.

I've driven a lot of GM cars from the 70's and my favorite transmission is the turbo 350. I would only use the turbo 400 on an extreme build, like a drag car. Even though they might seem similar from the names, they drive totally different, turbo 400's can feel kind of heavy and clunky, 350's are smooth. Also, just for amusement, if you happen to knock your car into reverse while driving down the street, the 400 and 350 react totally differently. The 400 will lock your wheels up and kill the engine immediately, the 350 will kill the engine if you don't give it any gas, but if you give it some gas it will start spinning the wheels in reverse.

Love the vid’s , I personally have a built 4l80E in my heavy turbo big block truck as it shares many hard parts as the 400 and its 90% street driven with the ability of having a high stall lockup converter

John Doc: “ Power Glide has the POWER TO FIGHT WHEELIES.” SHOWS The Boosted Rooster Doing a Wheelie with a Glide 😂😂😂🦅🦅🦅🇺🇸🇺🇸🇺🇸🐓

I loved my Powerglide in my 68 Chevelle in high school, neutral lock out, Hurst shifter ,trans cooler...man 76mph pop that bad boy into second and them 295 50 series Bf's would squak .Drove it daily for almost 4 years and it took everything a teenager could throw at it and I was destroying 5speed cobras and 400s all day.This was late 90s early 00s here in Vegas with extreme heat no issues, its amazing how much more they have improved the parts for it nowadays back in the day you just made sure you had neutral lockout and pray Lol im 41 now and still swear by powerglide to this day.great video great explanation 👍

Glides for racing, 3 or more speeds for driving.

I would be interested in learning differences in lock up vs non-lock up converters, pros and cons

I have a OBS short, wide regular cab truck. I got it down to 3200lbs. The interior is stripped with one aluminum plate for gauges and two aluminum seats. Truck is back halfed with a 9in ford with ladder bars. Rear adjustable shocks. The roll cage runs from the rear frame over the axle through the cab and runs out to the front frame horns. No inter fenders. The frame has holes drilled for weight. Still running stock front suspension. That’s about to change. I’m installing light weight A-arm and I plan to remove the front and side glass and go with Optic Armor. This should get me close to 3050-3100lbs. Running a big cubic inch SBC with a Built Power Glide. Truck best time is in the 6:50’s in the 1/8th mile. It has a 4:56 gear, so the power glide really helps me get off the line before having to shift and upset the truck. I’m hoping going with lighter front suspension and using Optic Armor I can get in the 6:30’s. That’s pretty good for a full size truck that’s all steel but the hood. I’m a big fan of the Power Glide even for street driving. My truck makes enough power that I don’t need a low first gear to get moving. Plus I have the 4:56 rear gear.. I had several people tell me you can’t run a Power Glide on something over 3000lbs. It’s all about setup and gearing. My truck was setup to race 1/8 mile. I can’t run down the interstate at 80mph for long distances. But at drag and drives I hope to cruise at 55-60mph. I’m excited to try anyway. Great video, sometimes I feel the Power Glides get a bad wrap, but it’s because guys don’t have them setup right. 🇺🇸🦅🏁🛻

For a drag car I’d always take the glide. But for a street car a th400 is nice, 80e is even nicer with the OD for a mostly street car

The lockup powerglide has been around since the late 90s. You didn't see them much after 2004 because they got outlawed in class type racing because people who had them were kicking ass with them. Only place you found them was grudge racing if they were willing to tell you. Once the rule went away they now own just about every record where they're aloud to be used. You can also get them for under 10k as a package. He's right in the fact if you want one of the best out there it's expensive. 15k won't even get it done in many cases. Also the Th400 is popular now with cars making 2500hp+ with the first gear removed. Some keep the 3 gears. Just depends on the tuner. It's not that the 2speed is better it's just easier to get to work. Nice video bro..

John you've definitely gotten more knowledgeable about Drag racing stuff since your early Drag radial video !! Keep up the good work.. I'm planning on running a 4L80E cause I daily my F-body so I like having OD ! 🇺🇸🦅🏁

Manual, no converter issues. Run an over under and you can do a 1st into over with a switch, then go to third and then 3rd over again with the switch.

How could anyone argue something that literally has the work POWER in its name

If you have a light car with a lot of power a powerglide is the way to go. I drove mine on the street quite a bit with a 4500 stall

GTO's had 2 spds. mine from factory lasted me about 350k on a 326 with 2 filter changes. my 500hp 455 is eating up th400 soft parts. thanks for the discussion.

Everyone knows a stock 4L60e is the best transmission on the planet 😂

Depends on the HP and the gears in the rearend

I like the Glide we have but we run the Chance converter (bolt together) 60 foot is great with a glide

4L80E=TH400+OD+ lockup torque converter

Damn, Reid Case in the house!

Why is there not alot of views on this channel. Sad

Thank you for the information im gearing up to start building my 1987 camaro and just these little info vids help a good bit. Keep up the good work cant wait to see how the cow flys with the new wheels and such.

I’m rolling with a th350 in my foxbody. Honestly love it. Making 550hp in a sbc and with 4.10 gears and 3 speed reverse manual valve body. It’s very streetable.

I think the new hot setup is the turbo glide. Glides certainly have their place. The downfall of a glide is the same now as it has always been. It might be a lot lighter it also means its a lot weaker. You can make a seriously strong glide but its certainly going to cost. If your willing to sacrifice weight for strength but you still want a better first gear ratio then the 2 speed turbo glide is what the industry has turned to. I think it also depends on where your budget is. If you want something that will work behind a dump truck and is built for pure strength and you dont want to invest 5k in a tranny then a 400 is where its at. The 400 is an excellent option for someone who wants to go racing reliably on a budget. Your going to sacrifice the hp that all that extra rotating mass robs though. If your not so much on a budget and you are shooting for every 100th that you can squeeze out of the car and you dont mind all the additional maintaince then a glide is for you. Knocking out weight is just free horsepower. There is a reason why in stock eliminator and super stock most guys are running glides, 200r4, c4 and 904s with 3 clutch packs in them. Weight=hp. Just my 2 cents though. Nice video thumbs up.

Hey bud know im late to comment on video but i think its badass move and its gna rip like never before imo!

I owned a 71 Vega with a 283 4B and a 2 speed Powerglide and LOVED IT. It's a great street tranny. I am not sure of these new versions but the originals like I had could also be pushed started. 👍

Great video.. easy to understand.. but reading the comments I see some confusion over a built PG vs stock PG.. A stock PG is still good for the street in a low HP car say 300-600 hp after all GM put them in 3400 lbs + cars.. after 600hp it's best to put some stronger parts in them up to 1000hp with a blanket or shield of course .. After 1000hp you really need a built PG with a aftermarket case... Low HP cars with a stock PG work better when the car is 3000lbs or less.. Any thing over 3000 lbs street sometimes strip car really needs to be a th350 or th400 to get all that weight moving... After 1000hp it really don't matter.. It will be a built transmission anyways.. 1000hp + cars with a built PG is less weight and gives you more time to settle the car down before you have to shift... Any strip car that's a 1000hp+ a PG is the way to go..

I heard one advantage of a non-lockup converter is that they can handle more horsepower and torque than lockup ones 🤔. Nothing necessarily wrong with a non-lockup converter.

Th350 here. Freakshow converters. About to build this trans to hold 1000+hp

Good choice on the glide! I’m running a 1.80 Reid Cased Glide with a Pro Mod Gear Vendors I It. Best of both worlds!

Also Powerglide take about half the power to turn compared to a TH400. But I have the TH400 in my 12’ Camaro with a centrifugal supercharger. I do not have as much power off the hit as a proper turbo setup.

I have a 1967 impala with 327 and a powerglide and i can tell u the powerglide is great cus u can launch and wind 1st gear waaaaaay out then 1 shift n ur in 2cnd and thats it n it just keeps going in 2cnd!

The answer is "it depends" because its a loaded question. You cant answer it without being more specific about the application

👍 great content lots of good information here keep it up good luck on the track.

John, keep doing your thing Bro 👊🏽

some shops are starting to do a race T400 case with powerglide internals, best of both worlds

Out of all the big transmission companies who’s best? Chasing a 1500-2000hp powerglide 💪🏼

I had no idea on the either transmissions great lesson.

I have a rebuilt 4ll60 in my 95 Z28 and I love it.😎

I want to put one on my my 280zx with my 350. My rear ended is 3.9 so I need less reduction on first so I feel like the powerglide would be a better option.

Great decision. Your going to pick up a ton with the reduced rotation weight. With your SBC the turbo 400 takes about 25 to 40 hp more to spin it. Your going to feel the difference when you make your first pass with the glide. Good luck.

John your awesome man and your content is killer !!! Quickly has become my favorite channel !! Thanks

At what power level do you feel either changing 1st gear in the 400 or going with a glide is necessary? Excited to see how much better the COW leaves, suspension dialed in & Glide should be quite a big improvement since she likes to Hit those tires hard!

I’m building a 3200lb road car with a tubular rear chassis. 1200 rwhp and a BTE glide. Hope it’s good. The NZ champ prefers a th400 because he loads it up in top.

John be putting in that work

Which is better? Whichever one will help you Stay Toned. That's the real answer.

Why run any of them run a 4l80e same as 400 but has over drive and lockup few mods runs 1000hp from factory sooo

Both are good aslong as thier not automatic....kickdown cable on a carb is just asking for meltdowns and 400 A/T is asking for a hot cabin

I have an FTI TH400 and matching FTI 3600 stall converter (to keep it somewhat streetable) and love it. Highly, highly recommend FTI! Though with my new combo I’m likely to run into a somewhat similar situation you’re in and may have to switch to a glide. But if I do, I’m putting a gear vendors unit (has been plan for the 400, but haven’t done it yet) behind it and turn that 2 speed into 4speed, sorta;)

I don't like the idea of only having one gear to grab but I can't afford a fast enough car to need a powerglide lol

I had a 78 jeep cj 7. Full time 4 wd w a hydromatic 400 .it was pretty sweet

Outfit looks good.

John thanks for all the great vids. What stall size r u running and what are you launching at generally? Also - if you use a 2 step which is part of the question above are you WOT on launch and letting the 2 step hold you.

Shout out from Australia jon doc love ya channel

Look at that you taught me something new!

60K soon! Awesome!

Very cool video. I've always had stick shifts, but it did answer some of my questions concerning the powerglide.

We have run power glides in Top sportsman cars for years.

Since you said make a comment if you have any questions I guess i'll drop one in here because i'm just curious what you think. I'm a young car enthusiast that's trying to make his dreams a reality and trying to soak up as much knowledge as possible. I'm building a pro touring setup 1970 Chevelle that's going to be setup for autocross, but i'm going to be putting a twin turbo 6.0ls in it so it should be at least 1k hp, I also plan on driving it a lot and maybe taking it down the strip once or twice. I'm leaning towards powerglide but am just curious what your opinion is since you're much more knowledgeable than me

How about the rear end gear ratio with the power glide, will you need to change the ratio now?

I usually use a late model cd009 pr tr6060 in my builds because I am either drifting or coarse racing. I was just curious what a powerglide was.

3yrs later....You still hanging out here in the comments? 🤣🤣🤣 Love all the videos bro, Freaking amazing content here folks, if you havnt subbed yet then what the hell are you doing! You know the drill get this channel the likes and shares it deserves so we can keep getting the amazing content!

Well the glide is a perfectly streetable trans gm ran many versions of it up till 64-65 whn the norm turbo hydro came out chevy had the power glide till 65-66 and for some cars even after tht due to da turbo hydro being a option altho some companies like pontiac buick caddy ran either a 3 speed or some even a 4 speed roto hydro trans till early mid 60s...some even had a "dual range" roto hydro trans which changes the shift points in the trans due to usein diff fliud passages.....honestly its about one gear/tires and how many times you wanna shift....a turbo hydro either the th350 th375 th400 ll have to be shifted twice where as a glide just once.....and as you said has a longer first gear allowin you to pull further i the power curve before shifts.....

Can we get an updated video of this? Now that you seem to run a 2 speed 400 more frequently

7:00 close your legs who’re 😂

I'm ready to see some action man, you gonna be rolling lol keep up the great content

when running the 1/4 mile in the cow what differences will you see going from the TH400 to the glide? Like does the glide hit your max rpm sooner, because I am thinking you will hit high gear or 1:1 sooner in the glide than in the TH400. Just curious. By the 1/4 mile the TH400 is stretched pretty far in the cow I would imagine so just seeing if the glide is more suited for 1/8 mile passes for you.

Running a PG behind my Big Block 9.Oh Ford engine. using 1.76 Straight cut gears. I'm building my own trans :-)

I have a single turbo coyote and want to do a TH400 swap, I only plan to be 1000hp at most and drive it pretty regularly. What would you recommend I do TH400 or get a stage 3 of my factory trans?

Could you have launched the 400 in second gear and got similar results as the powerglide?

I believe Coan makes a 1.90 gear set for Turbo 400

Dedenbear cases, transking and Borg Warner internals, with Neil Chance's converters. Oh and Trans King is out of Houston.

So which transmission made the car run faster ,quicker ?? At the track ??

What power range do you think necessitates a swap to a glide from a 400? I'm building a turbo ls foxbody, somewhere around 900hp for track use. I haven't picked a trans yet but was debating on 400 or glide.

I running a th400 in my 3300lb, will it be cheaper to just shortening my first gear or just do a powerglide?

Great video and very informative keep it up bro

There are SO many options you can get for your PowerGlide. Which ones do you recommend, why, and at what power level?

I'd like to see John Doc and Cletus McFarland run a couple of times :)

Both my cars fbody & foxbody have the power glides with the th400 input shaft,,let’s set something up,, fbody on fbody??

Man these cars are pigs so I'm curious to see how well the glide works for you. It probably would have been easier to just say that by the time you configured the th400 to work well for your setup then you would have ended up with a turboglide. Way more practical to just go with the powerglide so I'm glad to see this.

I really enjoyed this video

Keep making the great videos! When are you gonna build the Colorado with the choo-choo boy turbos?

You really should have a lock up in it John.

I'm only interested in highway speeds. Isn't running out the engine or not.

I always feel like, John Doc is watching meeee...

😎🇺🇸Hey Buddy 👍 Great stuff as always! very informative ✌️🤙

So is a th400 good for a daily driver

Do you have to swap a engine frame on a 90 Camaro rs that has a v6 to install a 454 big block

I have run T400s for years with zero breakaqge..I am building 2 new cars and plan to use nitrous at the launch...every trans co that I talk to has a different opinion..1 car will be about 3000#, the other..2600#...suggestions?

I have a dart 347 ford in my 88 foxbody and have been debating on either a th400 or glide, my problem is getting the right parts for it to work

Manual valve body recommendations for the glide? P/t quick release?

On power glide can you use Reid case and stock power glide internals. Look for power glide to use in my bracket / super street car. I like the idea of the Reid case for I don't have to use Blankets or external shields. what do you think?

solid housing rear end !! get rid of cv type joint axles

I know most people have their own opinions of how to do it. But how did you do go about burnouts with the th400 at the track? Burnout started in 2nd then shift to 1st once at the line? Or start in first and quick bump to 2nd to finish. then back to 1st at the line?

I have a 91 camaro running a 2 speed power glide I am having a hard time finding a driveshaft for it any suggestions?

Why not just leave in 2nd? and miss first? If its that much trouble?.
