Muncie 4 Speed Transmission Repair - Fixing a poor rebuild
HTML-код
- Опубликовано: 10 апр 2017
- Some tips when rebuilding a Muncie 4 speed. Hard shifting and gear noise existed after what seemed like a good rebuild. I took this job in to investigate why these problems occured. Rebuilding transmissions and sourcing good quality parts is a challenge for any transmission rebuilder.

Im 58 years old and life long diesel mechanic ... when I was training young mechanics I put emphasis on detail as you do so well. Its priceless to have that quality and glad to see its still out there.
True professional
Thank you
High school auto shop teachers should make these videos mandatory veiwing for students. Teaches craftsmanship, honor, and attention to detail. Great series of videos Paul - thank you.
The master. I was intimidated to rebuild my muncie but I bought his book which walked me through. Excellent teacher and excellent video. I like how he shows not just how it goes together, but why and how things work.
Thanks
There is no one else to my knowledge that makes such thorough and informative videos of manual transmissions as you Paul. All the info that you have gathered from years of doing this is shocking, most people would never look for the things you do when taking a box apart. This is what most rebuilders do and thus the customer has problems later. Please keep the videos coming, we know they are much work for you but we certainly appreciate them.
Thanks for watching and I appreciate the comment
This is what you are paying for folks, experience, not just parts! Nice work.
Thanks
I go to you for manual transmissions, i go to hirem for auto's. Those can be seen here: ruclips.net/user/hiramgutierrezvideos
I'm an old mopar racing rebuilder. I've done my share of both auto and manual and both of these channels are well worth the time to watch.
I love watching the work you do and following your lucid and insightful comments about what you see and do in working on these transmissions.
Leonardo da Vinci worked in oil paints, Michelangelo worked in marble. you sir work in 80W90. Hopefully you are still out there providing qualty service with an attention to detail. Any customer that has or will use your services is lucky to have you around.
Really, really useful! One of the best transmission videos you can watch. Beautiful explanations!!
Paul, I really like that billet aluminum mid plate....next rebuild I'll be giving you and order for parts....thanks for the hard work and efforts in keeping the best shifting muscle car era 4 speed alive in these times.
Another great video. I've personally called Paul for some of these issues when I rebuilt my M21 and he was more than happy to chat with me and be able to sell me the correct parts. Thanks again Paul!
Wow theres so much that goes into building a proper spec 4 speed Paul your videos are a master class.
You could go crazy with all the mixing and matching of parts if you dont know.
Another great video Paul. I super enjoy your informative transmission videos, keep them coming and thanks again
Thank you
You are a amazing teacher. I bought your book and it’s a great tool. Thanks for sharing your wisdom and knowledge with us.
Great video, I worked on some manual transmissions when I was a dealer mechanic, I learned some stuff from you. Thank You
Your video's have been a great help to me in the repair of my three speed mk2 zephyr gearbox ,no professional repair was interested in doing it,your help has been priceless thank you.
You are very welcome
Fantastic video, love to see the rebuilds and its nice to know whats inside and how it works for a change.
Great video Paul and I'm envious of your wealth of knowledge. I've been a mechanic for 30 years now and pride myself on doing the job correctly and attention to detail so I can very much appreciate your professionalism in your videos and gearboxes. Knowledge such as this is ONLY obtained by years of experience. I don't do enough manual transmissions to see patterns of issues or have enough data to support one theory or another so your videos help me to gain additional knowledge of things to look for during a rebuild. Thanks again and keep them coming.

Good stuff. I’ve been rebuilding Muncie’s for myself and friends since 1983 after taking a night school couse on a Muncie and an Automatic Transmission. Back in ‘83 I converted my M20 in my 70 Z/28 to a M22 b/c I wanted the whine even though I prefer the M20 ratio’s. I bought all new gears/parts from my local GM Dealer and it’s worked out perfectly.
great video, I really like the short videos that address a specific area as much as the longer videos.
I like the way you pay attention to detail . you speak clearly and use great lighting. you are a professional at heart. I love your program.
Thanks so much 😊
Morale of the story, if you want it done right the first time take it to Transmission Master Paul. Great video sir.
Very true
Attention to detail. That is the difference between a good mechanic and a great one. Thanks for a great video.
Great video. So many details to consider. It's no wonder very few rebuilders can get it right.
I have been working with these boxes.....for years.... can never learn enough !!
TY.. you will hear from me... Best Regards, M.
Will be assisting my mechanic friend with my M21 repair/rebuild & conversion to an M20. Your videos are a great help for me, a complete beginner to the Muncie world. 👍
Very interesting video Paul. Thanks. I am happy to say that with the help of your book, videos, and a couple emails, I successfully rebuilt my M20. Proud to say "I did it myself"!
Awesome. Great to hear
Thanks a lot for the shared knowledge on the rebuilding of transmission. I believe many people have learnt one or two things on rebuilding the transmission
7:40 nobody checkin quality.
Love your stuff. You are bob ross of gears.
Another fantastic and greatly informative video Paul! Thank you very much for sharing your knowledge and precision craftsmanship for all to learn from.Looking forward to the next one!
Thanks a bunch
Thanks Paul. Always looking forward to your videos. I consider them a gift, a gift of knowledge. I can't wait for the next one. Cheers.
Thanks
You're the Tops! Thanks for sharing your knowledge and I enjoy your style and high quality camera work.
Definitely the info I was looking for. I have 3 sm420's that I will be picking through to make one solid case. Also good tid bit about all trans. I'm lucky enough to live hour away and put parts in my hands before I buy. Thanks again👍🏼
Sir, Thanks. You are a rock star for manual trans. I appreciate your videos.
Hi Paul, I love your videos. I have recently purchased 2 ,M-20 4 Muncies, both of which were supposed to have been rebuilt units with less than 1000 miles on them. The first I installed in my 64 SS Chevelle popped out of 3rd gear on deceleration. I pulled it out and found worn and chipped shifting forks and the brass rings dont seam to grab like they should. The trans also seams to have a noticeable stiff spot when rotating the tail shaft while on the bench ,when its in any gear. When in the car it up-shifted great and at 65 mph was noise and vibration free.The speed teeth on 2nd and 3rd gears are double cut and look to be worn back over 1/2 way. The sliders are pretty sloppy. I believe I will end up rebuilding this one to fix the things that were done wrong or not done at all the first time.
Great series. Plan on pulling my 4speed this year and refresh as 3rd great synchro maybe shot.
Super video Paul. Your experience and attention to detail is unsurpassed!
Thank you
Very impormative,i myself is a mechanic and currently doing an overhaul for scania gear box.
Another excellent video, your attention to detail is incredible !!
These boxes are so simple compared to the Japanese 6 speeds, but I still wish I watched your videos before rebuilding mine - so many little tips and tricks that all add up
Was working on a 2010 Mitsubishi Lancer Evolution GSR, which is a 5-speed manual transmission and it wouldn't shift into reverse. When I took it apart I noticed that the shift rail had a bur on it and was hanging up the reverse gear. I learned a lot from you Paul and it really came in handy today. Different transmission yes, but the concept of how a transmission works is still the same.
Great to hear. Thanks for watching.
I was the Resident Product Engineering Manager at the GM Muncie plant for a period of time and I have to say that you have produced an excellent video. There are few people in the world who really understand how a manual transmission works. Nice job. E.S.
Thanks.
Informative video ! I'm dealing with a bad rebuild right now myself . It's a 65 Muncie with the 7/8 shaft . The builder left a spacer out of the cluster assembly and the rear snap ring .
Hi I'm a newbie with this transmission repairs I have a Ford F-150 1995 and having problems with shifting from 2nd to 3rd with the synchros and they subscribe to your Channel that's the best thing I could ever done you're very very smart and a professional in what you do God bless you with those special gifts I also purchased your book out there on Amazon for repairs keep up the good work God bless you
Thank you for your support
You explain how to tell when it's good and when it's not, differences in new parts, and the importance to notice tolerances.. Thank you for the education! I used it rebuilding a saginaw 3 speed in my '70 Chevy Van. It never shifted so smooth or had such a positive feel since I owned it. Thanks again!
Thanks for watching.
See, what's so nice about this situation is that so many people simply assume that old cars are naturally clunky and unpleasant to drive. And the go-to solution is always to upgrade whatever's bothering you to whatever is new and modern. While there's nothing at all wrong with that I think a lot of people go that route based on a misconception of what the old Hardware is actually capable of.
gw from badass cannons iam 1 of your subscribers love your work running a olds 455 i added a muncie 4 speed used a year ago week ago started to get a loud squeal pulled tran took apart spun input shaft bearing was going to rebuild it butt after going threw your book on rebuilds decided to get newer type super housing and going to get all new parts and build and save the other for another day the old one is a numbers match 63 vet, trans, so decided to keep it all together and do it another day so got some stuff ordered .waiting on more cash to get more stuff.i cant wait to get going on this i built the motor 30 years ago cant wait to do a trans,
Sounds like a great project
I can't believe the builder chewed up that gland nut like that and shipped it. what are people thinking of. great video Paul thanks for sharing your knowledge.
Great video Paul, outstanding explanations of operation along with fit-up specs and tips!!! Louis S.
Paul, I just discovered your vids; they're an absolute jewel as a resource. I'll be reaching out to you soon for a rebuild kit on my m-22. Thank you.
Welcome aboard!
I've found that the pitting or lash wear marks are indicative of the case hardened surface have been worn through. I'd replace them else noise will be evident. "Attention to details", as you say can't be overstated. Great video. Thank you.
Your videos are fascinating. I can't watch them enough!
Thank you
Enjoyed watching this: a very informative video. Thanks
Thanks for the video I really enjoyed it and learned a lot my first time in going into a 4 speed happens to be a Saginaw but you still showed me a lot. Thank you !
Awesome video man you explain stuff quite well so that people can follow along and I appreciate that
Thanks for watching!
If I go to sleep with your videos playing continuously on a loop, I’ll forget how to rebuild carburettors, but I’ll know my way around a gearbox.
Nice video good advice I put one together by readying a book long time ago when was young you make it look dio easy thanks
A true professional as it should be bravo!!!!!
I didn’t realize there was that much difference in the parts of a transmission great work
Yes there is
Superb video. I learned so much.
Thank you, Paul
Great info Paul. I always say, the little details that you don't pay attention to will always come back to haunt you.
How true
Breaking down my first t19....unbelievabley helpful.
Great video Paul!
i'm a mechanic and i learn alot from you
Thanks for the reply. Will wait for your mid plate
they are available in steel and aluminum on our website www.5speeds.com
Wow great video! I look forward to more. Thank you.
I not only enjoyed the video , it helped me better understand my M-20 Transmission. Thanks again. Jack Panzica aka Corvette Vagabond.
Thanks for watching
You are the principle of the Gearbox..Thanx
No we have nothing to do with that company. Gearboxvideo.com is this channels website. Our main site is www.5speeds.com
Paul!!! Thank you!!!
Thank you for the education!!!!
A great, informative video. You are certainly a master of the Muncie 4 speed. You taught this old dog some new tricks!!!
Wow, thanks!
@@GearBoxVideo I have rebuilt just about every type of 3 and 4 speed gearbox over the past 40 years especially the Muncie, but to describe you as a"Guru" would be an understatement! Amazing!
Why thanks..
So much I dont know - but thanks to you I’m learning. Thx. I live in Denmark were the prices for a rebuild is out of proportions. So, I have by my self recently rebuild a T84 and a T90 for my 1944 Willys Jeep MB - both had the mandatory popping out of 2. gear problem. Currently the 1947 T90 is in the jeep because it’s a way stronger gearbox. Not original but when driving off road as I do it feels like the best option... Any of you guys having thoughts on the diffences between the two?
You show the old adage; you gotta know what you're doing and why you're doing it. Wish I lived closer :-)
And a lot of people today aren't mechanics, they're parts changers.
Smart Guy. You must have been doing Muncie Trans for years. Thanks
2021 marks 40 years. Thank you.
Thank you Paul I love your transmission rebuilding vedios.
A grate lnsruction and learning example please i also purchase your new Muncie book . Have all the parts you require to rebuild m21 to a m22 thanks I learn a lot jim
I do. It takes a few days for me to get the parts together. Visit www.5speeds.com
this man is a grand master
Very nice presentation, and comparison. I can see why Tooloaders were superior back in the 60s.
Great job sir ! Very educational !
lots of great information, well explained.
ANOTHER GREAT VIDEO THANKS PAUL
great stuff such good info. I think all tradesmen should be watching your vids, let alone gearbox builders. I believe that mating surfaces have been attack with one of those flap sanding discs on a 125mm grinder by looks of it, bad very bad.
Its so common place, because people want to save time.
good job Paul.
Appreciate the advice.
Great info Paul.
Glad you enjoyed it
Excellent video Paul, thank you, very informative as usual..
Thank you
Wow, this is awesome info! I'm starting to wonder if my rebuilt manual trans was built with faulty parts. I've taken my trans to four different places, and they all seem to stumped at the fact that all the parts are new inside, but for some reason, the trans temporarily blocks the shifts before it goes into gear. It never grinds, there's just a weird delay.
Often overlooked is the quality of the synchronizer rings, how they grab the gear, and also proper clutch release
terrific info man love it I have a 72 EL CO improper installation of the u joints caused me to have to pull my Muncie 4 speed got him on stands and your video's have definitely gave me the confidence to go deeper as I have pulled it out before about a year and a half ago.rattling from trannie when I start up but goes in gear..?
Sounds like a great ride. I had a 69 El Co SS 396. If you need any tech feel free to email me at support@5speeds.com
Great video, thanks for sharing your knowledge, keep the vids coming.
I will keep em coming
Very good video, you give great information , your experience shows.
Thank you
Thank you for sharing this video Sir, really appreciate it.. Thank You
Learning loads. Keep them coming
Thanks for watching!
Hey Paul. Another great video! Was wondering why you changed from the autogear cast mid plates to the aluminum ones.
fiddlerpin Autogear changed, I didn't. I make a steel billet plate and an aluminum billet plate. Soon I will make a nodular Iron plate once the tooling is done. Im not impressed with the AGE cast aluminun plates, although some people do use them, they are not as accurate as my plates
great video very informative learned something new today thanks Paul !
Thanks for watching
would love to see a t45 t56 rebuild if you have one come through.
Wow! great expertise, thanks 🙏!
Very well done! Thanks!
