Mercedes 722.6 Chrysler NAG OVERHAUL complete

This video covers the complete overhaul of the Mercedes 722.6 RWD transmission used in many RWD and 4WD vehicles. This transmission is also commonly known as the NAG1 for Chrysler, Dodge, and Jeep vehicles. These transmissions are still offered in 2021 models and arrived on the scene in 1996!! In this video, I cover the disassembly, inspection, measurement, and assembly of the 722.6. This video is intended to teach a student or a technician the various components and measurements found with this transmission.

Accompanying this video are other videos including the 722.6: (note: if there are no links, it's because they're coming soon)

This is all part of the SIU Automatic Transmissions Curriculum, which can be found at:

Go to that site to view other videos on this and other transmissions, such as the FCA 41TE, Ford 6F50, GM 6T70, GM 4L60e, ZF 9HP48, GM 6L80, and Jatco CVT.

Such an excellent teaching video. This really helped me understand and complete my NAG1 rebuild for my 2006 dodge charger. I am curious though, during Park condition, the 3-4 solenoid stays active, why would this be?

Wow, the best video on 722.6 I've ever seen. Thank you very much, great job.

[sergioortiz]

Muchísimas gracias que gran explicación, que buena explicación a fondo 👋🙏

[krakass]

Great video. The only thing I ask is if you could post the clutch clearance specs for each configuration. I had a couple that had a different number of friction disks and the paper guide only gave specs without the compression tool

[jaehunlee]

Thank you very much for the awesome video. I am thinking to follow the instruction and overhaul my spare transmission 722.612 for my MB C250TD.

Please correct for 34:20 TURNS COUNTER CLOCKWISE! The Rear Sun Gear and K3 Clutch Hub should turn Counter Clockwise and Lock to the Clock! The same as F1.

Nice demo, would like a little more sound volume to hear you clearer .but really good tech description, and good knowledge good teaching.thanks

[Jovemdaluta]

Thank you for the video!
Question: Has anyone put new teflon rings (say Transtec or others) that leaked during the air test, kept them and they actually developed a problem in the actual vehicle?
(I say this because other kinds of Teflon seals need to "adjust under pressure" on most applications to actually seat/seal)

Bless you for sharing your knowledge ...

Please make a video for troubleshooting... so that we can decide if we can just flush fluid, change filter, change conducting plate, change valve springs... (All these we can do without taking down the tranny), or tranny has to come down to change the fiction plates, and/or sprag bearing, etc... These transmissions can be had for $500 on ebay. Instead of taking ours apart / out a few times, it might be better to swap with a used one, put on new conductor plate, filter, adapter, and fluid.
Swapping tranny does not require programming (like the meghatronic in BMW), am I right?
I see a "722 618 0" stamped on my tranny. All I need is another "722 618 0", regardless of what model / year of the car it came off from, right?
