Muncie 4 Speed Rebuilding Upgrades

[@humidbeing]

One of the best, if not THE best, transmission guys on youtube.

[@GearBoxVideo]

Thank you!

[@mangroveman8269]

You Sir are an artist. You have an intriquit knowledge of vintage performance manual transmissions unparalleled by few.

[@vandalvetteworks8008]

Paul, I had my M21 rebuilt using your midplate and rebuild kit. The guy who did the work was so impressed with the quality of the parts, the completeness of the rebuild kit and the features offered by the midplate that he wants to start buying them for his customers and his drag racing builds. Thanks for making happy customers out of both of us!

[@GearBoxVideo]

Thank you

[@mikedehart8344]

Thank you for the support

[@gregdavis4002]

If KZbin handed out awards for best videos--------you would win it. I'm also blow away with all the knowledge. Wall to wall content with no dead fluff.

[@nedmaxwell6996]

I called you and you told me I needed to adjust the clutch linkage on my 60 Vette. I thought you were wrong but I thought it would be worth a try. While adjusting the linkage it broke. Great. So naturally I blamed you. A coupla hours later it’s all together and with 1/4 inch extra adjustment it works better than ever. Nice considering I've had this beast since 1972. About time it shifts right. Thanks for your help, your expertise, and your time. A generous check is in the mail. Okay I was lying about that last thing. Max.

It’s refreshing to see somebody that takes this much pride in their work and strives to do the job right the first time and actually knows what they are doing. This industry as a whole is full of hacks that are just here to take your money. Keep up the good work.

[@GearBoxVideo]

Thank you for the kind words

[@garybonz]

I am not a trans tech, however I am a helicopter tech, and you are a pleasure to watch. Good standards and shop practices are almost a thing of the past these days.

[@Kashed]

Listen to this man, he knows his stuff. If you are looking to rebuild it yourself buy his book and get your parts through his online store, they are excellent quality. Thanks again Paul for your advice and knowledge. It was invaluable during my build.

[@GearBoxVideo]

Thanks for the compliments and watching.

[@Nomad-376]

Muncie trans are the unsong hero. Really an amazing product. I here 5spd tremec etc. but these are the diehards. Thank You GearBox

[@normsweet1710]

I haven’t owned or worked on a Muncie in years..... but it all came back while watching the video. I liked all the fixes for leaks too; it sure is smooth and quiet ! 👍

[@TheGuitarman1968]

Great video! I had a Muncie M22 "Rock Crusher" in my '71 Z-28 Camaro back in the day. Oh, that sweet "whine" of those spinning gears. Just a bit of trivia. Actually, the term "whine" is a misnomer. It is more of a "ring" or "ping" of the 20 degree helical cut nickel alloy gears clashing against each other at thousands of times a second. This creates a continuous harmonic that sounds like a steady whine. This is also how that "Whine" from timing gear-drive sets is generated. The problem with loud gear-drive though, in modern cars anyway, is that the knock sensor interprets that whine as a ping or knock and the computer retards the ignition timing to save the engine. The M22 gears are stronger, but louder, than the other similar Muncie 4-speed transmissions, and great if you have a lot of horsepower and torque spinning that transmission. 👍

[@tracymiller1884]

I’m amazed at the knowledge Paul has on these transmissions! Great video !!

[@sjd7188]

I bought a rebuild kit and parts many years ago from Paul back in the mail order days for my 65 GTO, still working very well .

[@Davinci12007]

WOW, Just wow. So nice, for a change, to watch someone who really knows what he's doing and has an appreciation for details and doing things the correct way, with a reason behind it.

[@larryperry2094]

I bet that thing shifts so nice. Great work sir. You are a wealth of knowledge.

[@GearBoxVideo]

Appreciate that.

[@normsweet1710]

Always a joy to watch you make a decent gearbox a perfect gearbox. Thanks for your tenacity to detail !

[@stevestock2439]

Paul, really like the depth of the specifics that you articulate into on your rebuilds. This information allows the the home builder to rebuild his transmission to an otherwise higher level specification. Again good science, and much enjoyment to the viewer/enthusiast.

[@catchulater7483]

I know this is an old video BUT the info is priceless and VERY well presented. Thanks man.

[@bikeski1956]

This is one of the most comprehensive videos I've ever seen. Clarified a lot of issues. A professional rebuild my transmission and buggered up the shifter install which caused it to be stuck in first or reverse, I ended up launching my Camaro in reverse into a bench that did significant body damage. I sent him a photo of the misaligned shifter, untightened linkage bolts, missing mount bolt, and he's pretty much gonna end up paying for this.

[@robertbramley2065]

this guy knows the right way to repair or rebuild a M-22 great video thank you for your work, Real-Steel Classic Cars and Parts

[@JahanZeb1976]

Excellent upgrade to the old unit. Great job.

[@INNO222]

Your videos always provide enormous value and you given me a whole new appreciation for any drive train rebuild. I'm very happy that I subscribed to your channel. Excellent Paul!

[@snw56]

Great rebuild Paul. Always enjoy your work ethic!

[@klausphx]

Another Muncie Masterpiece! Built by one of the Best. Takes Years Decades Figure out Problems and Design Better Parts to Prevent Failures. When your Good Your Good !

[@GearBoxVideo]

Thank you for the kind words

[@sparkomatic100]

Very good! No one ive seen goes into to such detail and precision, care... etc, over these manual traany's! excellent job! Enjoy your teaching labs!

[@Wofski]

Another great demonstration of craftsmanship!!! Looks good man!!!!!

[@GearBoxVideo]

Thanks for watching

[@garywesterhouse851]

started my m22w build today been doing some refresher watching your videos some more today so i do not miss anything the gear set I got from D&L transmissions were perfect ,well i guess my break is over back to the shop ,counter gear cluster pin time cant wait to put this in my truck thanks for all the information and keep up all the good work .

[@ytwhite5930]

Wow,brings back memories...I rebuilt lots of Muncies back in the day.Seeing your upgrades is a sigh of relief(I particularly like the countershaft upgrades). I haven't touched a 4spd. trans in many years and I've got two of them to rebuild,I thought I would refresh by watching a video.Yours was the first one I came across. I'm glad I did,excellent informative video. Thanks so much.

[@lukeoforcas]

I traded a guy installation of a TH350 for a M20 in his Model T hot rod a couple decades ago. The plan was to upgrade my 79 ElCamino Saginaw with it. Put his car up on the hoist, did the entire swap. Didn’t even notice until months later, when I pulled out from under the bench. It was a M22. Score!

[@lucky1time811]

These things look so much more simple than what I’m used to seeing over at precision transmission. Good work and loving seeing old school stuff!

[@GearBoxVideo]

They are. However like anything it's attention to detail and knowledge.

[@clintwhite4372]

It's good to see a new video, Paul. I'm digging the content. I enjoy working on transmissions too. Anyway, keep up the good work.

[@chickmagpunk]

Beautiful video Paul. Always learning from your work, keep it up!

[@tomb375]

Excellent JOB! GREAT Video! Nice to see a true craftsman at his work. If I ever need any transmission work you would be the guy I wanted to work on it! Thank you.

[@michaelr6205]

I too love watching your videos and listening to your expertise. After seeing all the details/ upgrades, the last scene where you pan over the assembled transmission, just truly beautiful. Great stuff. Thanks for taking us along for the build.

[@GearBoxVideo]

Thanks for watching.

[@hotrodswoodshed7405]

I'm fairly well schooled at the automatic transmission thing, but this straight shift old school gearbox approach is a new Venture for me. Thankfully you have WONDERFUL detailed good advice on the assembly as well as upgrade tips. I very much appreciate it

[@David-kq2mi]

Paul, I just watched your Muncie 4 Speed Rebuilding Upgrades. As mentioned in an e-mail I sent to you, I own a Saginaw 4 Speed :) nonetheless I learned a ton from this video! And for everyone out there ... Paul is the real deal! He says in this video he gets back to inquiries quite soon. I contacted Paul via e-mail on Dec 26 with a Saginaw question and before you could say JACK FROST (I'm from Edmonton, Alberta, Canada) I received a reply the same day! It's easy to see why theres no substitute for knowledge & experience. THanks

[@GearBoxVideo]

Appreciate your feedback. Thanks

[@timruiter5460]

Own some of your books! Great information and instruction. Thanks!

[@Theoriginalmalcontentcorner]

I'm a Mopar guy myself but I still love watching your videos. Keep up the good work.

[@GearBoxVideo]

I would like to get an A833 in here ,.. when one does come in the shop, I'll do a video.

[@Theoriginalmalcontentcorner]

@@GearBoxVideo I would have offered up mine but I just had it rebuilt. Seems as though a PO ran it w/o oil. Needless to say- new gear set was in order.

[@kennethjosephson134]

@@GearBoxVideoYour videos are extremely helpful as I need to go through my tired M-21. I have an A-833 from my long gone '68 Charger R/T. I plan to eventually install it (along with the Dana 60 and 440 from that car) into a future B body project. If you'd like to go through it for a video, I can send it. No rush to get it back.

[@GearBoxVideo]

Contact me at [e-mail] and I'm sure we can work something out.

[@dennisjensen7938]

You know your stuff. Your videos are on point. Keep making your videos

[@GearBoxVideo]

Thanks

[@jimcastillo8950]

Hello Paul, thanks for bringing back memories of my 4 speed Muncie. It came off a 67 chevelle and I had rebuilt back in the early 80s. I installed in a 55 chevy truck with a 283 engine and a 1972 posi traction chevy rear end. I believe it was a 3.21 gear ratio. If I had a car or truck project I would still put a 4 speed Muncie. I gave you a tumbs up and subscribed. thank you.........

[@MrConstant1]

Awesome video. Nice camera work. Master at work. Before I forget, a true basket case, too funny.

[@keithfilkins2043]

Thank you for the tips!!! Awesome video! If I need mine rebuilt I hope your available to do it.

[@josephmonaco4503]

Paul, I've had at least 15 Muncie's since 1973 until 1985 and my favorite is the Close Ratio Muncio M-21. I only wish they made one in a 5 speed. If they do, let me know. You have done, by far the best video's on Muncie's. If I ever need one or want to buy one, you'll be the first person I call. Good day ,,, Joseph

[@jazbuh1794]

I've watched at least 20 of your videos and I wish I had gotten into this as my Job. I think its awesome how you have taken all the issues of the OE boxes and built upgraded replacement kits. Lol I use to live in Florida too. Great Videos, really opened my eyes to how transmissions are setup. Looking online to buy some old used ones to rebuild for fun.

[@chevytruckjerry]

Awesome videos. I’m doing a M21 for my C10 drag racing truck and this video is invaluable! And when I close my eyes, I can picture Harvey Keitel teaching my how to upgrade my Muncie....anyone else hear that?? Anyway thanks for the awesome videos!

[@tundro27]

Excellent information as always, Paul...thanks for putting out these videos! Really helps us guys that are doing rebuilds on these Muncies!

[@jeffhelton2735]

I just hope this younger generation will hang with these older guys and still continue with the trade but you have to change with times when the old guys are gone going to to be for industry. Old guys will take care of something if they do it and the knowledge they have

[@jaybailey8044]

Great information on the Muncie M20 Transmissions I like the upgrades you have made and added to this transmission also. This will make a good transmission way better than factory.

[@andrewnewman1248]

Love ❤️ your work. I have learnt so much from your videos. I bought your book years ago. It’s such a shame to see companies like Hurst stop manufacturing in the USA Regards from Australia 🇦🇺

[@GearBoxVideo]

I never said they don't manufacture in the USA. Some components are. It's assembly issues and attention to detail. Something the American assemblers need pay attention to.

[@neapolis6919]

Great job Paul! Very detailed video and really like how you spend the time to show how to do it right! Don't make the secretary mad! She might teach you a lesson or two! LOL. Have a great day.

Hi paul, I've seen many of your videos, you're just the guy we'd like to overhaul our transmissions. Unfortunately, from France it makes a distance... :D . Keep on with these videos, because even if I'm unable to do what you do, it's a wonderful help in understanding, how transmissions work.

Thank you.

[@GAGE1959]

I really dig yer videos. You sir are a master at your skills and knowledge of the Muncie 4 speed transmissions. Keep up the great work Master !!

[@a-75n5lee4]

I completely agree. I had trouble out of my Honda TRX450R transmission the forks kept going out and 2nd gear along with it so I had to argue with the builder that I wanted everything down to the smallest bearings replaced and I had new gears sent to be micro polished and cryogenic treated the shift drum and forks coated with a anti friction coating and the results a transmission that usually needs replacing after 1 season lasted 3

[@pablogarciavasquez6637]

¡GREAT MASTER AND GREAT WORK !GREETINGS FROM PERU.

It's great to see you do it RIGHT! As we always said with engine rebuilds: If you don't have the time to do it RIGHT now; when the hell are you going to have the time to do it RIGHT?

[@GearBoxVideo]

Exactly. I have a huge library of factory service repair manuals. It's amazing how many people will not invest in a manual but want to work on there own vehicle.
