6L80 Valve Body Disassembling Clean and Reassemble

YT225
Footage of the Rebuilding of the Valve Body of the GM 6L80 Transmission, that I did in 2022. Transmission is still going strong on about 30,000 Miles now. It was a good rebuild.

Kudos to you for taking on that monumental task. If that was me doing the rebuild I would have parts left over. Thxs for the vids!

[@HVACRServiceTech]

Oh no that would really suck to have that at the end. Lol

[@czechmate6916]

You are braver than I am to something like this and I admire you for that.

[@HVACRServiceTech]

Thanks. Yea, I had to figure it out. Not willing to pay $6000 for someone to do a bad job

[@thesilentonevictor]

Man you made it look easy true mechanic do it yourself

[@HVACRServiceTech]

Thanks. I spent days, probably weeks worth of time researching and learning to be able to know everything about how that transmission operates comes apart and goes together. I never want to go into anything not knowing what I'm doing

Great video! I'm working on a 6L45 with 100k miles. After replacing the end plugs, the 1-2-3-4 and 2-6 end plugs fit so tight it doesn't touch the retaining clip, no tension on the retaining clips. Is the springs worn out? can i get similar springs from my local hardware stores?

[@HVACRServiceTech]

No, can get from a hardware store. The plugs should fit tightly enough to Where You cannot wiggle them at all, but with lubrication in place like some fluid the bore plug should be able to move in the bore. You say you replaced the plugs, do you mean you bought new ones? Or are just reinstalling the plugs that you took out? I'm not sure about the 6L45, but I think it should probably be the same, they should have tension. can you move the valve in the bore like I show at 19:05 in the video? It should be able to fly back-and-forth. And I don't believe that the Springs wear out over time, unless something stretched them out farther than what they're made to stretch out to or squeeze down to. It's probably that the valve is stuck in the bore. But you can't just use any regular Spring.You'll need to order the right springs for your transmission.

[@HVACRServiceTech]

So both of those valves that you mentioned rest in direct contact with the bore plug and under spring pressure from the opposite side of the valve.Once both halves of the valve body are put back together, i don't think the clip can fall out, but Im not positive about that. I would look more for debris, possibly in the bore or on the valves, causing the valve to be stuck and prevent the valve from being able to move freely within the bore. If it is free to move and the spring seems too small, hopefully it didn't get mixed up with any of the other ones, because that would be a mess to try to figure out, I'd imagine. Keep me updated, and let me know your progress.Good luck

[@MatthewDannevik]

Did you rebuild the clutches or just cleaned the valve body?

[@HVACRServiceTech]

@MatthewDannevik I did replace all the clutch packs. I soaked them in new fluid overnight and even tested the pistons with compressed air through the ports that connect to the valve body. I have a lot of other footage from the rest of the build that I need to find the time to upload.

58:30 brother QUESTION PLEASE, I wish u kept the camera at that paper a little longer, i can screenshot and see the sequence but how tight should we screw all those different 7/8/10 bolts? Is there torque specs? Would appreciate if u answered, stuck at this part now

[@HVACRServiceTech]

@@jamesethan3749 yea, give me just a min to find them

[@HVACRServiceTech]

@jamesethan3749 click on the link below. It should ask you to download a 108 Page PDF file. That file is the actual ATSB Service Manual. Page 108 has all your Torque Specs. Let me know if for some reason you can't download the file.And I'll figure out another way to get the information to you atoc.ru/uploads/manual/5fb79aebb40df.pdf

@@HVACRServiceTech if you link it in description for future people it would be a life saver. I spent SO MUCH time rewinding your video and trying to take screenshots and most were still blurry 😅😅😅 wish i had this at the start of my rebuild journey, but better late than never!

Thanks man!

Welcome. Thanks for watching

[@jamesethan3749]

What was the wash u used? “Mineral Spirits”?

[@HVACRServiceTech]

yes, mineral spirits

[@jamesethan3749]

@@HVACRServiceTech is it basically like acetone? Thats all i got at home.

[@HVACRServiceTech]

@jamesethan3749 no, it doesn't seem to me, that it's like acetone at all. Acetone, I think, vaporizes pretty fast. Mineral Spirits, takes alot longer. Acetone might work, it might not, or it might cause problems. I really don't know. It's worth looking up online before attempting it though.

[@jamesethan3749]

@@HVACRServiceTech - Can you use the mineral spirits (or anything else) to wash the TECHM? Mine is full of metal but its a computer so idk if there are rules about washing it? Plz give any tips 🙏🙏🙏

[@HVACRServiceTech]

@@jamesethan3749 You can use the mineral spirits for it for sure. It is a computer but it's also waterproof because it sits in a bath of transmission fluid.
