Chrysler NAG1 5-Speed Transmission Power Flow

[@lukemalloy2488]

The NAG1 and AW4 were the two most reliable Chrysler has ever used. Good vid. Tech since 97.

[@floorpizza8074]

That was very cool. I've always wondered how the different ratios were achieved. Simple, yet remarkably complex piece of engineering, explained very well. Thanks!

[@seanbordenkircher7854]

Thank you for making this so naturally easy to follow. I never thought I'd understand it but you explained it and showed it perfectly.

[@WeberAuto]

@tnphysics Hi, the input shaft connects to the input ring gear. The K1 clutch connects the front planet carrier and rear ring gear when it is applied in 2nd, 3rd, and 4th. The B1 brake, when applied, holds the F1 sprag which is connected to the input sun gear in first gear and 5th gear.

[@WeberAuto]

@durin23 Hi, good point. These transmissions are for training purposes only and are never going to be used in a real vehicle. I could not figure out a way to perform this demonstration without the screws in the slots of the housings.

[@ericterrill1785]

This is awesome thanks! I'm trying to diagnose/repair a Mercedes 722.6 and this helps visualize the inner workings

[@WeberAuto]

Glad it helped!

[@makaveli200369]

This is a great video this guy really knows what he's talking about

[@amhater]

I would pay to watch a video on how to completely rebuild the nag1...

[@SuperSynoptic]

Thank you very much for the technical review. I was hoping that you would comment about the pros and cons. Very informative. NAG 1 means New Automatic Gearbox. There are only a few issues I know of: 1.) water seeping through due to the dipstick O ring (white) which hopefully has been replaced. 2.) Chrysler recommends a triple flush which I have never performed. I would very much appreciate your views relating to the aforesaid. Thank you again.

[@PHXGlock]

This trans is also found in the 2012 and up Jeep Wranglers with the 3.6 pentastar engines with Auto Trans

[@WeberAuto]

+PHXGlock Yes it is. Thanks for the feedback.

[@pkranz937]

Through 2017. After 2017, the Charger Pursuit is the only vehicle using the A580.

[@jjlwis]

so this W5A580 is better than the 8R45 8 speed? ZF in terms of being reliable, rebuild-able, and somewhat fast shifting?

[@GBDGhotbear]

@WeberAuto great video,mercedes never had any real issues with that trans untill mopar started using it .. we had a recall for them with water leaking in from the fill tube,lol chrysler said to us to flush it and hope for the best . 90% of the time i ended up doing a compleat teardown and installing new clutches and seals :-/ ans flushing the coolers , great job, keep the vids comming .

[@jjlwis]

Thank you for the demo! also nice EPIQ box in the background!!!

[@tOSdude]

And now for reverse-second gear. Is it even enabled in Chrysler vehicles?

[@RoyalHippieGangstercom]

About 1:28...when he got to "annulus"-???...I nodded off into an impressed stupor. I started to think about why we listen to people we don't understand. I think it's because we love them, or the subject on which they pontificate, educate or phornicate. (i just made that last one up because I felt like it) - And for me, it's the 5 G-tronic. That's why I'm here. That little hunk of spinning metal, is what the engineers at Mercedes, say is 'the one', to put behind the venerable Stuttgart Steamer...aka The M120...aka a badass V12...(ask Pagani). (In other words, it can handle some torque.) - Now, back to the video... - That was dope!

[@WeberAuto]

Thank you and thanks for your feedback

[@biasbilt]

Brilliant explanation but with that workshop coat I kept thinking of Dr Evil from Austin Powers

[@atheris86]

awesome video. thank you for the explanation

[@WeberAuto]

Thank you!

[@asdefsaa9261]

How do you replace the Torrington bearings in the K2 clutch? Are they press to fit?

[@remedyfarm]

Cool. I just learned something about the 2011 Jeep Grand Cherokee I just bought. thanks!

[@MoparRob1]

Thanks for posting this!! Great info!

[@my-kecontent8488]

Do you have a video on how to check the valve body on this trany? thanks

[@WeberAuto]

No, sorry.

[@krakass86]

What would cause the shaft speed to spike once shift pressure and modulating pressure drop after shifting from 3-4.

[@asbargathi]

do you have videos regarding how to replace the conductor plate??

[@WeberAuto]

No, but that is a good idea. Best wishes

[@H3mif4v5r]

Which is better between a stage 2 NAG1 or a hellcat trans?

[@johnringoo756]

What's your opinion of the 42rle? I love the four speed rear wheel drive!

[@tomb375]

I would love to see a 722.9. Thank you.

[@hksjoshua]

What is the verdict on valvoline maxlife at for the NAG1?

[@jasonkellner6357]

I have a 2007 Jeep Wrangler it’s making a whining noise as I accelerate to go and hear like a whining like sound almost like a vacuum leak or like muffler loud sound but had it all checked and it’s nothing to do with muffler system at all. Need help

[@WeberAuto]

Make sure your fluid level is correct at the correct temperature

[@GeorgiaBoyJake]

what is the maximum trans temp for this transmission? My 2017 Wrangler has this trans and I pull a small camper (2800 lbs) and don't want to over heat the trans!!

[@THEIMPERIALDUCK]

After 15K Miles It Works Just Fine!

[@nicholaselias8542]

is this identical to the mercedes 722.6 transmission?

[@WeberAuto]

+nicholas elias Hi, no, it is the Mercedes W5A580. Thanks for watching.

[@PHXGlock]

+nicholas elias Yes the 722.6 is a W5A580

[@nicholaselias8542]

+PHXGlock I thought so... now they use mainly the 7 speed 722.9 on later model cars.

[@PHXGlock]

+nicholas elias Yes most Benz after 2007 have the 722.9 7 speed also know as the NAG2. 722.6 is Now a quite old design, I saw the first on in a 1997 E320 PDI back when I was still a snot nosed punk. When I left Benz the 722.9 was the main Trans we were dealing with.

[@kermets]

if its the 722.6/NAG1 it should have 2 reverse gears also not 1 like weberauto says en.wikipedia.org/wiki/Mercedes-Benz_5G-Tronic_transmission

[@kevingrant8563]

Hey I have an 05 chrysler 300c with the nag1 transmission. It will not move at all in forward or reverse. I pulled one of the trans cooler lines at the bottom of trans, started car and have no fluid flow. Trans fluid is where it should be.

[@WeberAuto]

Try pulling the gear selector into the low or 1st position and see if the vehicle will move forward.

[@kevingrant8563]

It doesnt move in drive and it wont let me shift it manually. Should there always be fluid flow when the engine is running?

[@WeberAuto]

Did you see if there was cooler flow in gear? If there is no flow, but the fluid level seems fine, there is an internal problem with the filter or pump.

[@kevingrant8563]

Removed filter. Pretty dirty. Fluid is pretty dark and has a burnt smell.

[@kevingrant8563]

No metal shavings or chunks. Car sat for 3 years not running. Think it was just the filter and fluid?

[@rishikataria7614]

Anybody have info on building a stronger NAG1 as Paramount wants almost 5k for their best/strongest model and I'm considering a Jeep SRT8 and getting a turbo kit, 2006-2010

[@aibarberguy3141]

Ever found that info?

[@lords2112]

Thanks...helps me understand my.2008 chrysler 300c 5.7 sedan(LX) better. Peace.i4i.

[@geraldhulton6856]

I have this transmission in a 2013 Chrysler 300 S and in 2nd gear it's making a turbo like whistling noise that increases in pitch with the rpms, it stops when it hits 3rd gear. Brought it back to the Dealer and they have had it there over a month trying to figure out what that 2nd gear sound is. They now told me they're going to replace my transmission with a re manufactured one but that's on back order. Any idea what might be making that 2nd gear turbo like sound? Thanks

[@WeberAuto]

There could be several causes: fluid level, worn bearings, worn gears, a solenoid problem. It sounds like a gear noise to me. The fact that it quits in 3rd gear is a good diagnostic clue. I would figure out what internal transmission part(s) stopped rotating in 3rd gear? That is how I would diagnose it. Best wishes.

[@geraldhulton6856]

WeberAuto thank you

[@okami6]

great information...wish i could swap my (NAG 1) for the current 8 speed transmission

[@WeberAuto]

Thank you!

[@alphamoto466]

ik me too the nag1 stock is rated for like 500 hp at the most i think, whats the 8 speed rated for?

[@josevatanaqota2346]

wow it helps.....thanks a lot.....need more....

[@WeberAuto]

Josevata Naqota Thank you!

[@AliVeli-vt2hl]

I have 2007 Jeep G cherokee 3.0 crd. I want make adaptaion how ı can make ? Same Mercedes ? Like push gas 30 second And wait 10 second like this ?

[@VladWork]

Thank you very much man!

[@newwavepressure6478]

I have an 06 Dodge Charger with about a hundred thousand miles on it I'm getting a vibration or shudder at low RPMs when maintaining speed if I shift it and manual mode it goes away it also shutters when I'm slowing down to stop anybody have any suggestions it shifts fine but after it runs through all the gears and I'm just cruising it starts to shutter I change the fluid twice and put a new filter in I also added friction modifier but nothing helped it it almost feels like the torque converter isn't disengaging could it be that TCC solenoid for the torque converter I just find it strange that when I shift it in manual mode it goes away

[@WeberAuto]

Manual mode bypasses the one-way clutches in the transmission. Chances are high that one of them are slipping. they cannot slip in manual mode because an additional clutch is applied to perform the same function as the one-way clutch. It sounds like you have a serious failure in the works. Best wishes!

[@newwavepressure6478]

WeberAuto thanks for the reply so I probably need my clutch discs replaced sounds lovely lol

[@filomartinez247]

jt12000, what are you going to do or did to remedy this issue? I also have a 2006 charger with the exact issue, if you repaired it what did it cost total please and thank you....@@newwavepressure6478

[@newwavepressure6478]

@@filomartinez247 i still have it its got to be the torque converter or the trans im goin to buy a factory remanufactured trans and now converter i flushed the trans 3 time with a new filter and the friction modifier nothing worked i did engine mounts just to make sure it wasn't that i had my overhauled like 2 years ago cost me lik 1500 if i had to do it over i would have put a new one in and did it right the first time and i wouldn't have the prob now so if u have the money go with a factory remanufactured can just spend too much money trying to figure out what it is by the time you put a torque converter and you have to drop the tranny anyway and might be the clutch packs or bad sprag or bad valve body and just a remanufactured valve body is about 800 good luck man iv bin just shifting it in manual mode after it gos thru all the gears and when im about to stop

[@filomartinez247]

``@@newwavepressure6478 ok JT thank you for answering, makes allot of sense not wasting money fixing one thing after the other, I will do the same ...thanks again...luck

[@Service4Mercedes]

Amazing demonstration! Big thanks for you. It's very interesting and useful! Now i know that clutches are infinite use for. all that can be broken is fucking hydratransformator! damn it

[@maresking22]

Does the 2013 charger v6 use this transmission?

[@WeberAuto]

+Omar Mares This 5-speed automatic was behind V8 engines. I think the Charger V6 got the ZF 8HP45 8-speed automatic. I could be wrong, but it should be easy to tell if you have a 5-speed or an 8-speed. Thanks for watching!

[@maresking22]

+WeberAuto my charger is a v6 and uses the 5 speed that's why I was wondering if those was the transmission in it and thanks for replying!

[@WeberAuto]

+Omar Mares It sounds like it is the NAG1 transmission.

[@PHXGlock]

+WeberAuto NAG1, 722.6, and W5A580 are all names for the same trans.

[@pkranz937]

The A580 was used behind the 3.6 engine through 2014. The 845RE was optional. In 2015, the 845RE became standard on all retail V6 cars, and the 890RE on the retail V8 cars. Hellcats use the 895RE. Charger Pursuits (all) use the A580 through 2018, and will switch to the 845/895RE by 2020.

[@Sean8294]

This is on my 2007 Jeep Grand Cherokee 3.7L v6 am I correct? thanks

[@Slapaho1100]

Sean no.you have a 4 speed trans

[@justintyme3043]

The WK Jeep (05-10) had NAG1 standard in STR8(6.1) and Laredo(V6). The Limited and Overland came with the Chrysler 45RFE.

[@TheChrisneal]

Is there a way I can talk to you personally I have some questions please.

[@WeberAuto]

Sorry, I am unable to provide that type of help. Best wishes

[@uhmeizuhngralphf0549]

what about the torque converter

[@WeberAuto]

Here is the torque converter operation kzbin.info/www/bejne/q4nKhKeqgLGmftU

[@VladWork]

On chrysler 300c nag1 transsmition?

[@di4241]

How is the 2nd gear in reverse applied?

[@WeberAuto]

a second reverse position on the shifter

[@di4241]

My car doesn't have a second revers position on the shifter. It has a Button(switch) that allows the car to take off in second gear in both forwards and revers directions. You showed in your video how the 1 gear in revers is achieved through the manipulating of the clutches, how is the second gear in revers achieved through the manipulate of the clutches?

[@bigdan911]

great , I have a problem with my NAG 1 .......at ekeast now I know where the problem might be

[@LindomarReis-e2z]

Muito perfeito

[@babak1969van]

Hello sir, is there any manual version of this transmission? I have a Dodge Magnum RT with the NAG1 and I am trying to find an easy way to convert it to manual. I know its a long shot!! Thanks

[@camman301]

You cant convert an automatic to a manual but there are swap kits to take the auto out and put in a tremec tr6060 in the lx cars

[@emmanuelquinones5084]

I'll never be that smart :(

[@alphamoto466]

lmao i bet you know that shit now?

[@geraldhulton6856]

Had this transmission in my 2013 300 replaced with a remanufactured one. Now when it’s cold(not warmed up), when I put it in gear it’ll make a “swishing” noise. If I put it back in park or neutral it stops. After I drive it a bit it stops making that noise putting it in gear. Seems to runs ok but the “swishing “ noise when cold, is that something I should worry about? Thanks

[@DimlyAwareHUmAn]

Actually it's made by ZF not Mercedes

[@WeberAuto]

Hi, I do not know where you found that information, but I do not think it is correct. Every ZF transmission I have ever seen clearly is marked with ZF casting markings and ID tag. This transmission is clearly marked with Mercedes casting markings. Please provide your source. Thank you.

[@Moist_Handshakes]

Mercedes designs their own transmissions. I'm not aware of them using ZF either.

[@pkranz937]

The Mercedes 5-spd is their version of the ZF model. As is the Chrysler A580. Mercedes does not build this transmission for Chrysler, at least after 2008. Chrysler first acquired manufacturing rights from ZF, and later purchased the design from ZF, and produces the unit at their Kokomo 2 plant in Indiana. From 2011+, it is 100% Chrysler.

[@mohamadshamim295]

Good

[@TheXilya]

I didn’t get the part with paper towel, won’t it be all wet and soaked in the oil? Doesn’t make sense

[@stevemartens7873]

NAG1 is not used on the Hemi'

[@WeberAuto]

2005 and above 300C

[@NecromancerGarage]

That used be the only transmission you could get on the HEMI cars with the auto. Now there's 8-speeds.

[@bleachinuri]

WeberAuto 2011-13 jeep grand cherokee with the v-6, and 6.4l,3.0l diesel uses this now, 2011 5.7 hemi uses 545rfe,2012-2013 5.7 hemi uses the 65rfe, 2014-on 3.6l uses 845rfe,and the 2014-on 3.0l,5.7l, and 6.4l, use the 8hp70 along with all other chrysler platforms using these engines

[@mopar9250]

bleachinuri challengers chargers 300s all with the hemis 5.7 6.1 or 6.4 did all use the nag1 trans the trucks used the 545 and then the 645 but they all have a 8speed behind them now

[@dieseltech3695]

Gary L yeah I know that's why I gave dates. It was used on lots of cars and trucks up to 2010 when it was decided there were better candidates for fuel milage and durability

[@zuestoots5176]

So another pile of garbage...

[@superflyshy4471]

Can I use the NAG1 from a 5.7 charger in my 6.4 Srt8 charger?
