I know nothing about transmissions, but I love watching your videos. You just breeze through these transmissions explaing everything so well. You make these so easy to watch. Keep it up.
+Sam Garrison Thank you!
It's awesome watching a professional. Thanks a lot for the video. I just subscribed.
Scott West I agree. Transmissions scare me, but these videos are great.
Professional .at.work
Great videos. I own three G.M. classics with Muncie 4-speed with 3.73 gears in each. Thanks to your videos I now have a better understanding on how my transmission is working and what it's doing as I run through the gears. Your special attention in rebuilding these transmissions turns them into a work of art. your a true craftsman.
The legendary Rock Crusher.
Thanks again Paul for the great build on my M22 drag speacial .it's got over 40 hits on it now and still working perfect . It's holding up to 800 hp very well!
Great video!! I really appreciate when an experienced, knowledgeable builder shares their experience with us all...like going to school. Keep them coming.
I've recently been interested in getting a C3 corvette but before diving in I wanted to know more about fixing the car. Your videos are nothing short of amazing. Thank you!
Fantastic information on the Muncie !
This is the first video explaining the details about what causes what problems and why.
It's a treat watching and listening to you do your art. 👍👍🏁🏁
Another reason why I purchased the M22 gearset etc from you!
+Pedro Montufar Thanks Pedro, appreciate it.
Excellent video.
Great info & how-to.
I totally dig your work.
+Mgon M Emjion Thanks very much.
Fine job. I will be shipping my M22 in the future for a truly expert rebuild!! I really enjoy your thorough explanations! Thank you.
Nice to find your channel. Looking forward to watching all your videos.
I know exactly what you're talking about, 2.20 first gear with 3.08 rear = dog terrible acceleration and some clutch slipping. Everybody used to get these on their new Z-28's with the 302 that had no low end torque and wondered why they couldn't beat anyone. Even with the 3.73 gears they came with it was not enough overall first gear ratio to get moving that well. Once you put in a 4.56 gear then things got better. Great info Paul, I have an autographed copy of your book and love it and your videos, thanks for doing these things for us.
+mike s Thanks for the kind words.
Came from EricTheCarGuy and boy, I really enjoy your videos. Your personality and the way you show stuff really gets my attention. I have a manual transmission conversion thing going on and have to check what you got to offer. Thanks and keep up the good work!
Great Vid, I was shocked by the parts and mid-plate in that trans!
Luv it... another home run !! Thanks again for your help today on the phone. :)
+Douglas Torone Anytime, thanks for watching.
Another great video to go along with your excellent book! Thanks for taking a lot of the mystery and myths out of transmission rebuilding. Really appreciate your time to share this information, and thanks for exposing the fraudulent and misrepresented parts.Quality, experience, and pride in workmanship.I will be upgrading soon!
thank you for the support.
You taught me so much in such a short time. Excellent video
You're awesome man, I can watch your videos all day.
+Christopher Mejia Means alot to me. Thank you.
You do an excellent job explaining the reasons why you do the things you do . Very refreshing to see a professional do quality work . I love your videos . We need alot more people on the planet like you .thank you so very much j,Nichols okc . Keep up the very fine job you are doing . Top shelf all the way .
Cool, thanks
Nice video, very good explanation to rebuild a gear Muncie gear box I learned a lot.
Thanks for producing this video! Answered questions I've thought about for years. BTW, I'm buying your books because of this video, wouldn't have known about them otherwise. Thanks again!
Appreciate the support
I've done over 50 of these back in the day. Had to learn to disassemble these blindfolded! My favorite was the very special M20HD with a 390 rear gear and a 2:54 first gear and the big main shaft. TH400 Tail...
Amazing work. So nice to see someone with such passion.
Thank you so much 😀
Your videos are great, I have leaned so much from watching, someday I maybe I can imply it , keep them coming
Thanks!
Pro at work always learn a lot from your videos Thanks for sharing the knowledge you have.
Thank you!
Your the bomb bro...Appreciate your diligence and honest proof..It doesn’t get any better sir..🇺🇸🇺🇸🇺🇸💪
Another great and informative video. One of these days, I am going to need one of those transmissions! Thanks Paul!
+RallyNova350 Your welcome
Thanks for the great information and presentation. Love your videos. And your passion for you work. Regards. Andrew from. Australia
I love the ratio explanation. I prefer a wide gear spread and an engine with a ton of torque and a highway friendly gear of 3.08-3.31. Makes for a fun street car. I had a 74’ Z28 with an M21 with 3.73 rear and while it was fun on the street, it was not fun on the highway. 3000rpm at 63/65 mph was tedious
Dude!! U are a bad ass!! I need to rebuild my m21 again and I gonna rebuild using your tips and methods cuz I don't think i did it rite the first time....thank u for making g these very educational videos.....I appreciate you sharing your valuable knowledge...
Fantastic video. Youre knowledge and experience really are teaching me so much about manual transmissions. Im considering a new m22 fom my Chevelle. Im running 4.10 gears, with a 400 hp small block, and an M21. Its a fun street car that isnt driven more than 1000 miles a year. I crave the old school whine of the m22. Dont need one, but really want one. Thanks for another fine video.
Thank you, I appreciate the comment.
This is simply fascinating. More vids like this i.e. fixing someone else's mistake and doing it the "right" way.
+Superdude Superdude Thank you!
Also great video, I was a GM tech years ago, have rebuilt a lot of Muncie 4 speed, great refresher course
awesome vid by the way keep them coming!
+Isaac Rivera Thank you!
Paul, Your videos are the best...Great production values and solid information....You must be creating an army of muncie rebuilders!!!
Can't wait to dig into mine and find out whats going on!!!
Thanks
When I was 18/19 I had the chance to buy an HG Holden sedan (1970 Australian GM) with a 307 Chev and a 4 speed gearbox my father advised me not to buy it as the gearbox had a terrible whine. Many years later I found out that the gearbox was a Muncie Rock Crusher M22, I still haven't forgiven my father , 40 years after the fact and 20 years after he passed away
Always impressive information. Very helpful indeed.
ur videos r grate very professional and informative ! 👊
good vid, learned and relearned a lot. Thanks for doing these vids ,,very helpful.
Thanks very much.
Working on a Mechanical Engineering degree and need to be studying for a test on Monday and I'm watching you tear down this M-22...Great videos man..Thanks for sharing your knowledge....Can't get enough of this...
Hope you pass. What school?
It’s the hypnotic effect of cogs?
4.11 my dad always said for street. 3.73 for more highway. nice vid!!!
Yes, those were the days when gas was .69 cents per gallon!
3.73s where still good for acceleration...now 2.79s or 3.08s where highway sets
He speaks my language , I like quality and I like how he knows what is right ,and he really comes off like he enjoys what he does .....I will call no one else when my trans money comes in.....new subscriber .....enjoy your work sir
Thank you
Wow Paul,
That was an excellent video pointing out sub par parts and WHY they are sub par pieces. I like how you corrected the bolt holes for clearance issues (I didn't know that could be an issue and I've got a '63 Nova). I'm going to come see you on my transmission rebuild - either I'll get one of your new ones or have you rebuild mine and strengthen it up and put the correct gear ratios inside it for a better driving experience. Thanks for the great info!
Since the video was aired it forced Autogear to change their machining practice and now all new extensions come with the bottom hole counterbored.
Incredible quality!
Thank you.
These videos are the best marketing!
Thanks for watching
Great explanation and video
Love your videos learned so much from you!!!!
Thanks for watching.
Excellent videos, very informative
Bravo, Paolo!
I got major anxious soon as you opened her up and all those needle bearings were piled up. Haha
Another excellent video !! Louis S.
JUST WATCHED ON 7/20/2018 GREAT VIDEO!!
Thanks
Great vid... Seems like you know your transmissions..
Hope to see more videos
gary, here again and another great video when i started my build and started looking for parts made the mistake of ordering a few parts off a co. on ebay seems like i always got to learn the hard way so now all my parts come from gearbox i make a purchase and they arrive in a couple of days ,i live in ohio so iam a few miles away butt so far gearbox has been good to me ,so keep up the good work and you are making pros out of all of us .
I am not associated with The Gearbox
What a grate vid bud .keep them coming :)
+stanstedgarage Thank you.
As always love your meticulous detail of the small items that should be addressed properly. Will contact you on the parts I will need Thanks
+fiddlerpin Appreciate that.
Great video !
Nice video!
ABSOLUTELY GREAT!!
Appreciate the comment. Thanks!
I remember reading a Chevrolet TSB (technical service bulletin) That told mechanics that had encountered cars with multiple pre-mature clutch wear on M-21 M-22 equipped vehicles to check for a minimum axle ration of 4.56:1 in order to be covered by warranty.
For those of you not familiar with TSBs let me explain, These were basically secret documents from G.M. engineers to the dealer mechanics explaining to them how to fix in the real world what they screwed up on paper. The TSBs were issued for Dealer Mechanics Eyes Only.
+biscaynenick Yes I have some copy of TSB's. Sad thing is that the issues were checked in cars that came in for other repairs avoiding the embarrassment of recalls.
great video
You are very good at this. I'd love to come work for you and learn the trade from you. You only do things the right way.
awesome video thanks
I have a 1966 Chevelle with a 427 and a manual shift Turbo 400 that has worked well but I’d like to change it to a 4 speed for the second half of its life. It’s my first car that I bought 42 years ago. I just discovered that you sell new M22’s. That’s fantastic. I bought your book too! Thanks
I'm not building units right now because the quality of the Italian gears and inconsistency of the dimensions is not to my liking
@@GearBoxVideo I can wait. I have 3 different cars that could use a manual transmission. 2 66 Chevelles and a 1970 Monte Carlo so it will be a fun project. I have your book too. They all have automatics so it should be fun to finally have a Rock Crusher. Best transmission name ever! Thanks
I love your videos!!!!!!
+black85chevy Thanks very much!
And this is why guys like this are in high demand- Very few want to excel in rebuilding gearboxes-Especially automatic transmissions which are even more complicated......If I excelled in the aret of building transmissions- Id want a minimum of $35 per hour as an employee plus benefits and all the overtime I could handle- Build 3-4 of these week.
Awesome videos man
Thanks for watching!
He's the best gear box builder Ive seen.
+Skeefoo Panama Thank you
+GearBoxVideo
Paul, BTW I subbed to the channel, Glad I found it,, I really like gear boxes so to get to see videos on a subject you like is always nice.
Great Video like usual Paul. Still waiting for some Toploader vids though!
Thanks
Good job
Great video!! Just surfed over from ETCG channel.
thanks
Great info paul, your the master. does your M22 transmission have that legendary whine with all the blueprinting just curious keep them coming.
+Ryan Jones Yes it does. Thanks for watching.
Great video thanks for the info. Only thing I didnt agree with was the direction the snap-ring was installed on the input shaft. I always preferred sharp side out to help prevent the possibility of it popping out of the groove. Maybe more of a pet peeve than incorrect, but I'm a stickler lol
If you install it as you say , pliers will not be able to remove them. The ring is cut that way so it doesn't slip off pliers. If your so concerned about this, just use Tru arcs instead.
Paul, you are the best, so impressive, do you prefer m-22 over M-22
I love your videos I like to know how to install the Speedo gear on one video
Thanks for the tech talk,You make understanding a Muncie easier and gear ratios.Can you explain how I can tell what my transmission came out of.I bought 2 Muncie M-21s and 1 M-22 from a friend in his junkyard for $300. all of them were in decent shape but I would like to know what they came out of.Any hints?
Really enjoy watching your videos!
Do you ever do a video on a ford toploader? Thanks!
marcus crammer The most recent video I did is very similar except for the side rails
My '05 Mustang GT was geared (stock) for fast 0-60 time. First was 3.32 and the rear end was 3.55 for an effective 11.8 ratio. Red line in second was just over 60 mph. No wonder a test driver for one of the car mags got a 4.9 second 0-60 time.
My first car was a 70 Chevelle ls5 Chevelle ,I bought it in 1975 it had a 4:11 rear what should the first gear been ,the car would always wheel hop bad when you would come out of the hole.im not much of a mechanic but loved your video.it was a m22 rock crusher
Great to see a pro call out all these counterfeit parts from other countries, there's no comparison. Will they work,? The video shows the wear on the shift forks from a few miles to shift forks I've pulled from boxes with thousands of miles and no visible wear. These inferior parts are garbage, I deal with this frustrating issue all the time.
Hey this is a really Good video !!! you know your stuff !!!
come from Eric the car guy. impressive!
Hi Paul,I am working on my 2nd Muncie rebuild. Thanks to you, this one will be more thoroughly done. You not only have the technical knowledge, but also the proper pace and clarity to keep it interesting and easy to follow. I built an Olds 350 W-31 replica. I used an M20 and 3:42 gears. Most of these cars were built with 3:91'S. I have trouble launching ( the car weighs 4200 lbs) but it really screams from 2nd on. Would you suggest a rear gear change or a first gear ratio change? If so what? Thank you
Probably an axle change. Because if you get a lower 1st gear, the ratio drops will be too wide.
Hello, A fantastic video thank you very much for sharing the knowledge.BrChandru
thank you
I wish i lived near you 👍😁🇭🇲
good video
All hail the Transmission God!
Thanks, but hardly a God. Trust me. There are many people much more talented than myself.
I really enjoy your videos - it’s rare to see somebody who now so much about a gearbox, who willingly and in good video quality explains and gives great tips.
I noticed in this video that the front bearing was lose and I have the same problem in my M21 gearbox.
On the internet with all its experts some suggest “gluing” the bearing racer to the case with some Retaining Compound like the Loctite 660 or 680.
Others suggest to punch a number of holes around the racer in the case - or maybe even a combination
What is your take on a problem like this?
If the bearing is slip fit, that is acceptable and I just use red loctite. If it has up and down movement within the bore the case needs to be repaired. I don't use them if they are that bad.
Enjoy your videos. I know it's 5speeds.com, but how about an MT82 rebuild video?
Dude, after watch 4 minutes of this video. I'm going to rebuild a 4L60e on video I've had for 3 months.
+blackericdenice Go for it!
+blackericdenice I look forward to seeing that video!
ArtemiaSalina 5 of them are up now.
I have 2 of these Muncies . They look great on the inside. How much to go through ?
Turbo 400 with 4.10 with sway bar with air shocks you can add ait to
Very informative showing the different qualities of what you use vs the after market. It shows you get what you pay for.In the future I will have you build an M22 for me, love the gear whine.
Happy Holidays to you and your Family
+Jay Smith Thanks, you have a great Christmas / New Years as well.
You cannot put a price on the advice and info here. Amazing how some people figure a way to get a deal on speed equipment is off of E-Bay. Only to find out it ends up in a scrap bin. Or in this case, Paul chucked the Taiwanese 'parts' into a cardboard box. I bought my M23Z direct from AutoGear in Syracuse NY. To my defense, I didn't know about 5Speeds the time I ordered from AutoGear. If I had, my Stingray would of had one of Pauls Spec25 versions of a Muncie 4-speed. In any event, cheap parts aint good and good parts aint cheap. Paul was very gracious to lend his advice on whether the Z ratio would work with a 3:36 posi rear gear ratio. My SLR is 10 to 1 with this set up, so 1st gear is fairly short. With all the steep terrain where I drive in the mountains out West that first gear comes in handy. My Corvette has excellent street manners and is a blast to drive now. Before, with the stock M21 ratio, I was either lugging or over-speeding the engine. Or breaking the speed limit by double. Over all a huge improvement in drive-ability. Thanks once again Paul, great video learning center.
Yo Mike,
So true,, notice how Paul picked up on the junk parts right away?
I'm pretty sure I'd be happy with one of your boxes.
Another excellent video as per usual. I wonder, can you make the gears in an m20 the same as an m22 as you just did?
There are M20 ratios in the M22 profile. They are called M22W
Just found this video.. great info!! I have a m21 and I wonder what the he would charge for the parts and labor??
Great watching and very informational!
I am not doing rebuilds at this point in time
Very very well presented. Excellent sound and clearly shown details. This stands out in comparison to other TH-cam articles. I have the original Muncie in a 67 Corvette which is drenched in oil from leaks. I plan to drop it out and rebuild it. Can the internals be replaced with the stuff you showed here to produce a stout M20 or M21? Can I do it? I have rebuilt a couple in the past, but of course, I am nowhere knowledgeable as much as you are. Will it require any machining for the new parts? Do you have the part kits for me to do this? Thank you and keep up the great work. Salut
Yes you can upgrade gearsets. People purchase upgrade sets from me every week. The old M21 ratio is not that desirable compared to the better ratios offered in the M22 line. You can do it!
