Features of the Spec-25 Muncie M22 4 Speed, Plus Muncie Rebuilding Tips

[@kittypigeonclueless5566]

Beautiful set up! I've purchased Paul's rebuild kit online and installed it as per his videos. I highly recommend buying from him. His prices are great, ship time is short and it's not made out of chinesium. Also...I've read up on shot peening but still haven't seen how it's done. That would make an excellent video!

[@GAGE1959]

This is a awesome video of the Muncie M22 Spec-25 4speed trans. Great description on the parts and the build. I so want a Spec--25 !!!

[@unclequack5445]

It just keeps getting better.

[@corvuslaeus9540]

Paul, thanks so much for your videos. Transmissions are my weak point in terms of knowledge and your explanations and on-hand examples make it so much easier! Looking to build a 65 GTO with a M-22 and understanding the guts is a great feeling. Thanks!

[@GearBoxVideo]

Thanks! Your feedback is appreciated.

[@chevyfan5303]

Excellent video. I'm very impressed with the many upgrades over the original Muncies.

[@crosby72]

Great video, really a lot of valuable info here!

[@GearBoxVideo]

Thank you

[@bigcalguns7782]

you have designed one hell of a transmission there..totally awesome idea bolting the countershaft to the mid plate like that very nice set up.

[@GearBoxVideo]

Thanks. I've got a new one on the drag boxes coming out possibly this weekend. Stay tuned and subscribe

[@bigcalguns7782]

GearBoxVideo sweet, i can't wait to see that

[@kenb1376]

You have excellent videos. I use them in my classroom. Most of my students wouldn't know a Muncie from a toaster, but I like this stuff.

[@GearBoxVideo]

Thank You.Where do you teach? I may be able to get you a deal on my book on Manual Transmissions. It has theory and High Perf stuff. I also speak at schools for free, if I am in your area I'd do that.

[@kenb1376]

GearWorldTV I teach at a SUNY school on Long Island. Actually I'm thinking of retiring (I'm OLD but still racing in NHRA Super Gas). Maybe I can get a teaching job in Florida.

[@GearBoxVideo]

***** Actually I graduated from SUNY at Farmingdale. I did a small talk there a few years ago.

[@unclequack5445]

Hey Paul, I'd only buy a Gear box from you that is if I was ever in any position to. Great Video as always..........

[@GearBoxVideo]

The Spec25 is designed for road race applications requiring synchro 4 speed transmissions. The T56 was never designed for endurance race applications.

[@unclequack5445]

+GearBoxVideo Thanks you are a very good builder.

[@unclequack5445]

@@GearBoxVideo Paul you Blue print your units with a lot more care and attention to detail than mass produced units like the Tremec TKO, there's no way they smooth out every gear like you do.... or do all the little things that add up to a much better shifting transmission. Great Video Paul.......

[@GearBoxVideo]

Thank you

[@marcchaffee7751]

why does that look like a ford bell housing pattern ? Your gonna get me excited !

[@SamnissArandeen]

Awesome work, awesome video, and I love how you share your knowledge to otthers freely like this. I do have a question, though. Does that 26 spline input shaft mean I can run any T56 clutch kit with the Spec 25? If that is possible, that opens up my options considerably.

[@GearBoxVideo]

Thank you. 26 spline input shafts seem to be the standard on just about every race transmission. If you have a 26 spline 1 1/8" diameter hub, the input will work. Whether or not it will mate up correctly depends on your bellhousing locating the transmission at the correct distance from the clutch and crank.

[@howardtutorials]

this maybe a stupid question but I've looked up this transmission n it seems it was used in late 60s (68) through 74, in gm cars n such. So my question is, do these go in modern cars? and if not how much different would a modern transmission be than this one for instance? sorry if this is dumb, im just learning about transmissions, as of about 5 days ago haha. whenever you n eric were together, thougbt this looked pretty cool thing to specialize in.

[@zxtenn]

Regarding the better oil flow of the sealed bearings VS cage is the length of service the same?? You are a smart guy, love your vids, you make some valid points as to use bushings on the shifting forks, any reason you using cast iron for the plate on this trans. as opposed to the one you sell?

[@GearBoxVideo]

Sealed bearings last longer due to less contaminants affecting the bearing life. They also reduce windage. The plate in the video was discontinued by the manufacturer so we made steel ones until I could come up with the funds to tool another nodular iron plate. The castings are done and we will switch back to nodular iron.

[@dearmanville]

I am rebuilding a MY6/A833 OD Transmission ( a General Motors COPO Chrysler trans where third gear is used for Overdrive) for a Chevy truck and based on what I've learned from you, am very disappointed in the sloppiness of the original design with the non-bushed gears and extremely loose fit of the hub/slider assemblies. Thank you for the knowledge gained, and I will be getting your book. I have purchased other S/A Design books and was impressed with the quality and information. Do you recommend sealed bearing for a street driven transmission...if can find them for this application.? The OM specs for this transmission required Dexron ATF, but do you think gear oil might be a better choice?

[@GearBoxVideo]

The clearances of that gear train require the ATF lubricant. There are no sealed bearings for that application since they are a special size.

[@dearmanville]

+GearBoxVideo --- Did New Process just tighten up the clearances as compared to the old days Chrysler used the A833, or did it have a fundamental design change? Thanks

[@GearBoxVideo]

Most units took ATF

[@lodr7869]

great video

[@GearBoxVideo]

Thank you!

[@jackn5048]

How long do the sealed bearings last until you need to put more grease in them? Or do they still get a little oil from the transmission through the ball bearing cover?

[@GearBoxVideo]

They still get oil. Ive pop seals off of bearings that had over 100,000 miles and they still look brand ne

[@65mustangmotorsports77]

Great Video's Paul. Question: About the drilled lightend mainshaft. Is this drilled over the full lengt?. And are you not afraid that it will brake. Best regards Paul from the Nederlands

[@GearBoxVideo]

It's drilled from the front to just before first gear these have been in 800 horsepower vehicles as well as land speed cars that have hit over 250 miles an hour I have had zero failures with over hundreds of transmissions that I have built with the shafts they work great.

[@65mustangmotorsports77]

Thanks for the info. Always nice to know more about the technology in the gearbox. Do you also 4 speed Toploader Ford. Rebuild and modifications - video. Thanks

[@davidgrigolla5495]

I'm on the West Coast. Can you recommend a company to Teflon coat a new Supercase and Tail?

[@GearBoxVideo]

Calico Coatings on the east coast

[@xramcam]

That is one bad ass M22.

[@gordocarbo]

Can you build one with the same numerical gearspread as an M22 but use a lower (266?) first? Is there such a thing as a 5 spd in this configuration? Tired of my T56 its just not getting it.

[@GearBoxVideo]

No 5 speed Muncie. The TkX is a good alternative

[@SupermanBPR9]

Are those parts available to purchase from you or another source? I am talking about the sealed bearings and caged bearings.

[@GearBoxVideo]

+SupermanBPR9 I stock everything. So yes you can purchase direct. Thanks for watching the video.

[@lewwoodthing]

Hey Paul, When will the Spec-30 or 35 be available?

[@GearBoxVideo]

+lewwoodthing This is my 35th year in business. I may do a special edition. I don't know yet.

[@lewwoodthing]

+GearBoxVideo Congratulations on the 35 years in business! I will be watching for special edition. Thanks

[@JT-yz4rj]

Paul, is the input bearing supposed to be somewhat loose against the bore of the case or should it be like a press fit? Following your book, was worried about spinning the input bearing in the bore of the case. Mine is loose with a new bearing. I can pull it in and out

[@GearBoxVideo]

Yes they are, they are slip fit.

[@mattdecker7376]

Nice Video!

[@GearBoxVideo]

Thank you!

[@idoaricha]

How did you done the teflon coating of the gearbox casing? can i do it myself or it's a special process?

[@GearBoxVideo]

There are companies that do that. Its similar to a coating used on a frying pan.

[@leozanazanian4057]

I have an M20 and I have a 10 spline input shaft, is there a way to stop the oil from leaking out?

[@GearBoxVideo]

Make sure the inside of the retainer and nut are in good shape and do not use synthetic oils.

[@brenna2100]

At 10:12 you show the hubs you call "ni-trier " ??? is that correct and who carries them / PS maybe the info in your book , ? I should have soon Thanks Paul

[@GearBoxVideo]

Nitrided hardened hubs. I stock them

[@brenna2100]

Ok thanks / Is that you on Ebay THE GEAR BOX TRANSMISSIONS LLC ? If yes ... I was ready to order 2 Muncie rebuild kits $120 each... but . I only see slider $34Do the Nitrided hardened hubs come as a unit hub/ sleeve. . What would the cost be for 4 units .. PS received your book today Hi- Performance

[@brenna2100]

Paul , I'm enjoying another of your videos . the Spec-25 video was helpful .... the front seal and retainer . Does all the input shafts of the super M22 accommodate the seal . About the syncro units , the units you used ( Couldn't make out the name) that has a better fit . where can I get them . PS ordered your book tonight .

[@GearBoxVideo]

All 26 spline inputs have a front seal.
