Incredible! Thank you for doing this! Your videos are well made and I’d suggest to continue!
@arod227 Thanks for that nice comment. I'll keep making them!
Thanks for sharing, makes the thought of rebuilding a 4l80e less daunting
You know, I can remember back when I was a teen in early to mid 90's. My Gpa had a truck not too old at the time that he paid a shop about $3k. Translate to todays inflation costs and bs, that's about $8k-$9k. I think altogether, at most a rebuild kit is $600-$800. This is well worth the effort. Thanks for this great DIY content that wasn't so easily available then.
@jamesbenge7724 It can be a bit more than that depending on your needs. Mine needed a new forward drum because the center bore was worn out. And of course a new torque converter etc. But yeah you make a good point. There are so many shady transmission shops out there ripping people off, its really valuable to learn the skills yourself.
Thank you for the time you spent making this video it was informative
Wow. Amazing detail and a fantastic job on the entire video, especially for fitting so much knowledge into a short version! Thank you 🙏🏼. I just started a RUclips channel and thought I was doing ok, but now I have a lot more to work on! I can’t imagine the time to put into editing! Great Job Viking!!
@AmericaFirst1974 Hey thanks for that nice comment! Yeah I think editing is a big part of making videos people will watch. I try to edit out as much of the fluff and empty space as possible so every second of the video has something useful in it. Good luck with your channel!
@@vikingmech Agreed and subscribed! Thank you so much man! 🙏🏼
Exactly the sort of video I was after; not a 3h step by step, but a quick oversight of if its within my wheelhouse!
@talljake Yep that was the idea. Hope you found it useful. Thanks for watching!
Yessir, basically looks like a th400 rebuild with a few extra fiddly bits!
Yes we would like the rebuild of the pump
@davenevarez4738 Ok I will get that underway. Thanks for the feedback!
@@vikingmech I would appreciate that as well.
Me too
Thank you for making this video. It was very helpful. I do appreciate it.
You get the good star😊
Thanks! Great video. I have a partially assemble 4L80E in my garage. I got sick and ended up in Hospital. Seeing your video has inspired me to go back to my project.
@SharifSalukis Wow, thats a great compliment. Thank you! Get well soon and get that project done brother!
@@vikingmech Thank You!
Great video! That’s the only part of a vehicle I’ve never have rebuilt is an automatic transmission. I’ve always said maybe one day I will give it a try. I was initially was going to run a 4L80 in my truck but I’ve pretty much have decided to go with a manual transmission. I’m more of a manual type guy but who knows I may decide one day to go back to an automatic.
@slingingsteel9744 I was the same way and I think a lot of other people have always wanted to rebuild a transmission too, but just thought it was too complicated. Hopefully everyone can see here that its not impossible. I love driving a manual too.
Thank you for making this video.
@darrentenold5451 No problem, hope it was helpful. Thanks for watching and commenting!
Fantastic video very helpful thank you!!
@curtislarab You bet, thanks for watching!
Thank you for sharing 🙏
great video! super helpful!!
Transmission Bench had a video series on youtube tonight with a few videos. I went back later and now you have to buy the video series or it comes with a purchase. Just my luck I cant find it now. Great video thank you very much.
@onestopfabshop3224 Yeah I watched a couple of his videos on youtube before purchasing the set too. The full video series is well worth the money. He goes into a LOT of detail that is essential for a first time builder. He's not sponsoring me or anything. I just think if you want to get it right, you need a good teacher for your first build.
Great job on your video. There are some key differences between the early model and the late model 4L80E. You found one difference on that Sprague in the overdrive/overrun hub. You have an early model (1993 and earlier) with the larger Sprague. The later units (1994 and above) have a smaller Sprague with a different groove for the snap ring. I noticed how you skipped right over how to assemble the two parts of the aluminum overdrive clutch hub. There is a special tool for that process, however it can be done without it as you probably figured out. It just takes some time and some patience! As an engine builder as you mentioned, there's one key difference between building engines and automatic transmissions that I've noticed. With engines, we always have wear limit specifications for things like cylinder bores, rod and main journals, piston ring end gaps and the list goes on. With automatic transmissions there appears to be none of that. It leaves the builder to "guess" what's ok and what's not ok to reuse. This has bit me more than once. I will now always buy new spragues, new shift solenoids, new TCC solenoids, new internal harnesses and new pillow block switches when rebuilding these 4L80E transmissions because of this.
@user-bv1sn2wm8l Thats very true. I noticed there aren't very good guidelines on what to replace other than "visually inspect" it. I tend to err on the side of caution too and I replaced all the solenoids, harness, pillow block switch and also the forward hub and drum. I didn't replace the spragues though so hopefully I won't have an issue there.
This is awesome man. Thank you!
@83SquareK20 No prob man, thanks for the feedback! Let me know if there's any part I should do a more detailed video on. Thanks for watching and commenting!
Very good thank you
Transmission bench is the goat
Watched the whole thing this will be helpful!!! Yes do a pump video if you already haven’t 🎉
Thanks! The pump rebuild video is on my channel here: ruclips.net/video/wiPA_OO4F_k/видео.html
I will also replace all of the bushings in these transmissions when rebuilding them. There is no wear limit specifications listed for them either.
Very helpful
That's a very helpful video. Thank you for taking the time to put this together for us out here that are hesitant about tackling a 4L80E rebuild. I would be interested in watching the pump rebuild if you find time to edit that video.
@Suds. Thanks and glad you found it helpful. The pump rebuild video is on my channel here: ruclips.net/video/wiPA_OO4F_k/видео.html
OH Hell,......I've been inspired....
@aubreyroche5080 Hahaa! Thats cool man. I wasn't sure anyone would even watch this video!
Great video, exactly the level of detail I was looking for, ATSG ordered, I’m ready to dive in, thank you!
@TheSargeK5 Glad to hear it! Thanks for the feedback and good luck on your build!
Good vid!
Great Video - Thanks for taking the time to make it. I might give this a go!!
@ThomasHegland No problem, thanks for watching and good luck on your build!
New subscriber!!🔥🔥🔥🔥
Thanks man!
In the video he show you the Word what year goes with what trans as far as the over drive hub
Good video I watched all of it you paid close attention and very good at explaining.
@RobinLovins Thanks! Hope it was helpful for you.
I chickened out at tightening the hollow bolt! I'm freaked out about breaking it!
I just did my first 4l80. When the intermediate shaft goes into the sun gear the lube oil holes have to line up. There’s about a 1 in 50 or so chance these hole will line up if you put the gear in first and then drop in the intermediate shaft. You have to put the 2 together and shine a light in the end to verify alignment. During assembly I noticed its very easy to pull this shaft up and mess up the alignment if a component is pulled back up. The shaft can easily be one spline off.
@kevinboutwell2243 Where did you find that info? Not saying its wrong but I didn't see any mention of that in the ATSG manual or the video classroom series I followed. Would be nice to know if I need to tear my trans all back apart again for that or not. Thanks!
Good question. I just looked in the ATSG book and can’t find anything about it. I had a friend show me that a while back thats done lots of 4l80s along with the bevel going down. I’ve also seen a couple rebuild videos of others that do it all the time and they line them up. I did it because monkey see monkey do principle. I just looked at a spare sun gear and intermediate shaft and the area where the hole lines up with a internal grove in the intermediate shaft. That hole has to be getting oil even when the holes aren’t lined up. My friend is out of the country right now so I can’t ask him. My gut feeling after looking is it doesn’t matter. The only thing i can say is the 2 holes lined up directly might spray oil better? If my buddy ever gets back in town I’ll ask him.
ruclips.net/video/R7JB8Jqcif0/видео.htmlsi=Z4Uc-47GSOuympUA
Start watching this video at minute 18. Like you said, the book doesn’t say it and there’s a groove in the intermediate shaft. I’m not sure but mine is definitely lined up.
@@kevinboutwell2243 I did find an answer here (post #105) that says indexing the oil holes is not necessary. A few other random forum posts seem to agree, so I'm thinking its not necessary, hence no mention of it in the book or videos. bobistheoilguy.com/forums/threads/4l80e-rebuild-on-a-suburban.284668/page-6
@@kevinboutwell2243 Yeah I found that same video with a search, and saw him line up the holes. I think this must be similar to lifters in an engine. They have oiling holes but they don't line up with the oil feed holes in the block and they're in a groove which would be entirely pressurized. So the orientation of the holes doesn't really matter. Thanks for commenting though. Always good for myself and anyone else watching to learn about this stuff!
Nice work!
Extremely Helpful , Thank You Very Much.
@RANDOMNATION907 You're welcome...and thanks for the feedback!
Great job
@toddsculley2710 Thanks!
Thanks. You should add 4l80e for dummies to title. Thanks again
@cameracamera1319 I just figured it would be helpful for beginners to see the basics and get an idea what it takes. Thanks for watching and commenting!
❤ wow, Thank you !!!! can you do this for the 4l60e??
Same here I built a motor but not a 4l60e💪🔥💯
@frankdatank7751 I'd love to do a 4L60e video but I don't have one to build. I imagine it would be mostly all the same steps.
Cool Man!!
Pump video please!
@timdontwannasay5889 The pump video is on my channel here: ruclips.net/video/wiPA_OO4F_k/видео.html
The reason why you overdrive planetarium is different because you're working with our earlier 4L80E trans he shows you that on the video I think you're working on a 91 to 01 4L80E trans look at the tag on the passenger side of the trans
@dennisalstonZ06 The one I'm rebuilding in this video is a 1998.
The he's working on in the video is a later model.
@@dennisalstonZ06 Yes the guy in the instructional video mentions his is a 2003 model. That would explain the smaller blue roller sprag in the overdrive drum.
Where did you purchase all your upgrade parts from
@christophernyquist3104 I got the main rebuild kit along with the video training course from transmissionbench.com. I got the upgraded clutch discs from summit I think. Also, if you need to replace any other parts, clutch drums, shafts, sensors, etc. I found a local place called transstar industries that is excellent. I believe they are a chain (like Napa or Autozone) that supplies transmission repair shops. Hopefully you can find one in your area.
What manual did you use to let you know what thickness, air checks etc?
@papergatorzfedducca7998 At the end of the video I show the resources I used. The ATSG manual has most of the info you'd need to know, but the video course from transmissionbench.com shows how to do the air checks etc.
@@vikingmech ok thank you and I love the video. I still have a few minutes left to finish it.
@@papergatorzfedducca7998 Awesome thank you for the feedback. That really helps me figure out what kind of videos people like to see.
@@vikingmech So basically as a beginner it’s best to assemble one part at a time? And when possible can do another one or a 4l60e😂😂😂
@@papergatorzfedducca7998 Yep one part at at time and in the right order. I highly recommend that video course. They show how to do each step. There are a lot of details I didn't show in my video but if you just follow their directions step by step, its not hard.
Would you rebuild my 4L80E?
@rickwaldo4150 Well I've only rebuilt one, so I'm not exactly a professional. I would try to find a good shop with a lot of positive google reviews.
