How to Rebuild a Allison 1000 Transmission | Duramax

[@davidgoliath982]

this is exactly the kind of person u want rebuilding your trans. very pro.

He's a pro for sure but not "Very Pro" You can see he's without gloves and a surgical mask.

I watched the rebuild from start to finish and I was impressed. I have rebuilt many transmissions and you impressed me at every step. I am 84 years old and you are all business. Thank you.

[@MrAdrianhdz]

man this guy put that back together like if he was tying his shoes , Experience shows much respect .

[@aman4189]

I can’t believe the number of parts that go into a transmission, and how complicated it is, you would think technology would reduce car parts and making cars less complicated. These guys deserve the respect & appreciation equal to doctors , engineers, etc , mechanics are way under appreciated

[@akonitony2]

Over 1,000 pieces in many of them. The imports are the worst.

[@armaletalia3254]

Good mechanics are under appreciated. Key word: good.

[@ivegonemad]

Nah, if anything technology makes it worse, they keep adding and redesigning transmissions like if they are cell phones lol

[@cl4367]

Watched it all. Its down in. Great video. Thank you.

[@CHICOB4261]

I have to tell you Truckmaster I have watched this video about a dozen times and this gentleman who does this rebuild is like an artist of the highest caliber. I am not joking when I say I would drive in my 05 GMC truck (Duramax of course) from Georgia to Wisconsin to drink some beer and maybe buy him a steak dinner. I love to watch someone do something with the kind of expertise and precision Mark does. He is in the “masters class” of his craft. Perhaps one day I will meet him. Thank you for posting this video!

I know NOTHING about automatic transmissions but I was impressed and captivated by this video. Firstly, the engineering that has gone into the development of this unit is incredible! Secondly, our teacher exudes expertise with the speed of his work and his rapid and clear non-stop narration. Truly amazing!

[@aaronmoritz9878]

I’m not sure how many times. But throughout the whole video I kept say, “that’s amazing”. This guy is so skilled.

[@aerialrescuesolutions3277]

Also, exactly what he said about " Making your own special tools to fit a particular application" This statement alone is golden truth. Total. Excellent. Quality. Jim

[@colinrathman2192]

i watched the whole thing and all i can say is i sure am glad my dad was a mechanic for gm for close to 15 years before moving to greener pastures. because there is alot of information to remember when rebuilding transmissions he helped me replace the tail housing on my lb7 without pulling the whole thing out when i let a u joint go to far.

[@aco246inf]

this is what im gonna do. but how far up did you have to jack it up to not have clutch plates move?

This mechanic is the best instructor in the internet....IK want him to rebuild my Duramax transmission.....

[@dieseljo2]

In my younger days I rebuild a variety of automotive automatics and a lot of 543 and 545 Allison's. The quality of this Kodiak rebuild is outstanding! The entire video was pure entertainment. Thank you for posting!

[@aerialrescuesolutions3277]

This person is totally beyond Qualified to do this. Awesome, I couldn't stop watching. I'll probably never do this type of rebuild, but as a mechanic it's great to watch a real Pro doing some serious work like he was sleeping. The upgrades are a must if you're gonna haul anything. Superb.

[@everardosalinasjr2812]

Not many mechanics like this man left!!! Very tuff to find QUALITY work on anything nowadays!!!

[@mtwz71]

What a good job on this rebuild. I really like Marks attention to detail and his style of building a transmission. A good and reliable transmission builder only come with time and experience.

[@jehoney]

The most helpful video on the Allison 1000 I have seen. All I was doing was replacing all of the solenoids and the pressure switch, but there is enough detail in this video of every part of the transmission so that it covered what I needed to know to do what I was doing. THANKS!

[@samthomas808]

I see why transmissions cost so much to buy , and rebuild, wow you have to be very smart to do that job. Good job very impressed.

[@FarmerSteveO]

“Professor” Mark! Thanks for the in-depth schooling! I would pay the freight to Wisconsin for a rebuild after watching this! That is 30+ years of experience in street and truck pulling builds right there! Thank you Josh as well! BTW, loved the cameo of Mrs. Kodiak with the 10mm spoof and Kile crashing the party at the end! Broken record here but your killing it Bro!!

[@7novalee]

Who knew how to design all these parts. There is gotta be 500 plus drawings to make all the trans parts. And builder/narrator is dong all the work from memory which is equally impressive.

[@UnderPressure04]

As an engineer and amateur mechanic, I agree that both the design of the thing and the ability to tear it down and rebuild are, at first glance, mind blowing and humbling. However, at least on the design side, keep in mind a couple things. One, no one person designs something with this level of detail. Obviously it is a team of people, most of whom have a very narrow scope- all they worry about is a specific component in a specific section of the transmission, and don't need to know or worry about much that goes on outside of that. Of course I'm sure there are technical experts within Allison that have a remarkable amount of knowledge of how the whole thing works, even they likely can't design things at the component level to create a working modern transmission from scratch. Second, keep in mind that what we are seeing is the result of 60 years of design evolution and iteration. It's not like someone, or even a large team of people, sat down one day with a blank sheet of paper and designed this from first principles. Rather, they were starting with a huge amount of proven knowledge and design history that they could refine and build upon for a specific application. That makes the design side a little easier to swallow. This guy tearing this thing down and reassembling from memory, though- that's just witchcraft.

Thanks!

[@tyrellboggs2863]

I have seen many tutorials and this guy just plain knows his shit. Usually the guy presenting this much material bores the viewer to sleep. Not this guy. Very knowledgeable, very sharp to all of the things that can go wrong and will if you dont watch this video. Or if you have not all ready made all of the mistakes and learned from them. Most of the people who make the small mistakes that lead to failure seldom understand what they did wrong to cause their failure. This makes it a lot more difficult to learn from your mistakes when you dont know what they were. This tutorial has to be one of the best at calling out all of the common mistakes the first timer is bound to make. Very well done. I really hope to see more of these tutorial videos for other types of transmissions. The presenter was able to make his points in a way that made the viewer pay attention. This was an absolute professional at work and it showed.. I wasnt bored one second. You didnt waste time showing stuff you didnt need to and you made all of your points very clear and easy to understand.

[@theyoungmechanic1677]

This is I deed the most in depth video of rebuilding a allison that I've see, I watched this whole video as i plan to rebuild my allison 5 speed in the 03 lb7, I will for sure reference to the video plenty of times to do this, I should be able to after all I am a diesel mechanic🙄

[@teamunicorn9389]

you'll be calling him

[@chevy5137]

I have an 03 with an Allison as well and there's no way I could rebuild it. I worked at a diesel shop but I was a welder/fabricator and autobody specialist and painter. I did do some basic diesel repair work as well but nothing to serious, I did know enough to do all the repair work on my own vehicles. Word to the wise even though your a diesel mechanic transmissions are a totally different game, there's a reason they have shops dedicated to fixing only transmissions, no offense intended. Me and my buddy both who know quite a bit about mechanical work tried to rebuild a 3 speed Turbo 350 transmission and it took us 6 tries to get everything right before we were successful and even after that when we put the assembly back into the bellhousing 2 of the 6 bolts in the bellhousing stripped even though we torqued them to spec so the transmission leaked fluid constantly. If I were you I'd let a professional rebuild your transmission or just buy a new one, thats what I plan to do since my truck has a lot of performance parts and is running 400+hp and I need a transmission that can handle that kind of power!

[@glyshorts9107]

Did you have success with your rebuild?

[@stephenleelawson]

There are literally millions of how to videos out there. Almost anything I need help with to understand how something was designed, function and/or repair. Most of them are done by amateurs that bore me to death and leave me with a headache. On a scale of one to ten this instructional video scores a ten. It is fast paced and professionally done. Excellent job fellas.

[@TruckMaster]

Thanks

[@marcusupshaw829]

Mark is a total pro. He is awesome at what he does. I loved the video and the incorporated sense of humor

[@MrBILLBO58]

It's about understanding what it's designed to do, what we want it to do, what it used to do, what it didn't ever do, then. how to make it do. Then, finally, ultimately, how to eliminate the weak link; clear that ID-10-T error code behind the tiller assembly. Great job, Grasshopper, bullet proof. What we've done here; pushed that driveline failure to a less expensive more easily accessible area; slip yoke, u-joint, ring and pinion, axle spline... ;)

[@thewarnextdoor6.5]

I love my 2015 Duramax 3500HD I just went on a camping trip pulling a 32foot travel trailer my Allison shifted like a dream and never got hotter than 196°. They really are bad ass transmissions and engines.

[@redlywaxer]

I have a brother in law who is at this level of skill and has been building automatics since his teens, although he may not specialize as much in the Allisons. He has built a bunch of them and really likes them. He also builds many antique units from all over the Eastern US. This builder reminds me so much of him. And their shop is always jam packed with waiting jobs.

big murph just gotta find the right shop. But yea doing it yourself can save a bunch and be a learning experience

[@redlywaxer]

Man no kidding! Many shops only tear down to point of failure vs a complete overhaul to bring back to new like condition. Notice most only give 12 month warranties. A minimum warranty should be 3 years or 36,000 miles with a check at 12,000 miles/1 year.

[@Jessehermansonphotography]

Man, transmissions have always been the scary part of cars to me. I’ve rebuilt engines and many other parts. Worked in a fab and tuning shop for 3 years. A trans always has been something I avoid at all costs. This didn’t necessarily make me feel confident in doing this rebuild myself. But it did make me know I need to send my trans to Kodiak when it goes!

[@travelingbadger]

I just sat here and watched the whole video, and I don't even own an Allison transmission. Fantastic content in this one, and as for Mark, he is a master at his craft. It is great to see that there are still some people out there that take pride in the things they do.

I spent from 1994 to 2014 in Various GM dealers and had many, many transmissions apart but never an Allison. We just never seen them fail other then NSBU switches. The size of that park pawl is incredible! I remember when these first came out GM said that the park pawl in the LCT1000 was designed to hold the full GVW of the vehicle plus a trailer at the max tow rating of the vehicle. I thought that thing must have been big but it is a huge chunk of steel along with the pin.

This guy is amazing. I’ve seen several builds on the Allison but no one makes it look so easy. You almost forget that the automatic transmission is one of the most complex devices ever invented. One misplaced part will render the entire unit to nothing more than a worthless brick of metal. However, I was disappointed when the milk crate was sent packing. When my 01’hits 300k and the engine comes out for a rebuild, the transmission is getting shipped to this shop. Great video on a true master of his craft!

Great tuotorial, I was a mechanic for years and a pretty good one as my record supports - but I always considered serious transmission work the realm of trained and experienced professionals such as yourself so I never did more than fluid and filters, the occasional modulator or rear output shaft seal replacement etc. I never was one to dive into anything without knowing what I was doing first, that tenet served me well and kept me out of trouble.

I remember back in the day, one could head to a Mechanic parts store and go to their book rack, find your vehicle truck or car by date and model and BAM most everything was there that you needed to get greasy in your garage or driveway. But a video, TONS MORE USEFUL, eliminates a lot of guessing.
