8 years late to the party but so thankful to find your video. Thankyou
Awesome book. I just picked it up and read it cover to cover. Very well written and excellent pictures. Keep up the great work.
thank you i enjoy all your videos....rebuilt many early Harley transmissions witch also have loose needle bearings now i'm going to try to make my M21 a M22...thanks again....i also bought the book
I’m trying to get the nerve up to rebuild my own 1980 Corvette manual transmission. I can rebuild carburetors and I have a press, so I think I’m mechanically inclined. Your videos are amazing, you make it look easy even though I know it’s not. I can tell you know your stuff! I agree with your mods and techniques. Thanks for sharing your knowledge and experience!
I bought your first book (yellow cover) Great information and would recommend to anyone rebuilding a muncie.
Thanks for buying my book. Much appreciated.
Thank you! Exactly what I needed! Great detail and explanation.
Thanks
I just bought your newer book on Muncie Only trans. My muncie in my 57 chevy jumps out of gear going downhill in 3rd gear. Like all the new Autogear parts available.
i purchased your book. job well done.
Hey Paul! Love your videos brother! Can you please do a Ford 4-speed Toploader video next? Thanks for making these! 🙏
Send me a transmission
Thank you, Paul.
I am building a T10 and it looks the same as a muncie. What differances should I be aware of? This video helped me alot!
They are somewhat different... watch this video th-cam.com/video/cYULq42H8Eo/w-d-xo.html&lc
Great video.
What an amazing video!
Thanks!
I went through trade school for auto mechanics in the mid 70s we had to pack the bearings with the wheel bearing grease and no one was wearing gloves back then. I messed up when I trusted one of the instructors that got me a job at a marine shop that was supposed to send me to evinrude school so I never worked in a auto shop and never went to evinrude school
good video
I Always find a little gold nugget. Thanks
Great to know, thanks for watching
I purchased a 1970 camaro rs with the m21 in it. It's stuck in 2nd gear. What will cause that? Also, I purchase your book off Amazon before seeing this video! Thanks
If you disconnect all linkage components and physically cannot move the 1-2 shift shaft by itself out of the 2nd gear position, a few things usually happen. The rings flatten out and the 3 little keys slip out of the slider and wedge the slider in 2nd gear position, A missed shift can sometimes tear up the teeth of the slider and jam the mashed teeth on the hub and rarely a detent comb breaks in the cover and jams the mechanism up. If you do disconnect the linkage and it easily is moved manually out of 2nd gear position, then it may be time for a new linkage. Visit www.munciebook.com for book updates. Thanks for getting the book.
I can just imagine how smooth a full roller bearing Main shaft Muncie must shift like ever since you showed us the one with full rollers Ive been dreaming of pulling through those gears, Ahhhh almost a religious experience.........
cool, thanks for pointing out the fact that wheel bearing grease is ok to use for this..that's what i used on my m20 and then wondered if it was ok. a lot of guys say grease and then come to find out they use assembly lube like you use but call it grease. I'm curious why there are no caged bearing available for these like you use in your spec-25?
The SPEC-25 is mostly run in 3rd and 4th. There is no severe loads in 1st. I want full support of all the needles on a street / strip transmission.
well that makes sense. it sure looked nice just dropping a couple cages in each end and your done.
my rear reverse idler gear has about 0.060 up and down play on the shaft . thats with the rear 0.030 thrust washer . the idler gear doesnt appear worn at all . it measures 36.30 overall length
Have you looked at the bushings for wear? Or do you mean endplay?
@@GearBoxVideo endplay
also bought your book from barnes nobel can you recommend a couple of places to purchase the italian cluster gear for
my m21 trans with 1" pin 1966 model year.
Autogear discontinued the M21 countergear. They still make the M20 piece which we still stock. Those are made in Italy. The reality is, if you are mixing gears, used gears against new gears, getting a Taiwanese M21 cluster is fine. The new Italian M20 sets are a great redesign. Info is here: goo.gl/0zWCaF
GearBoxVideo thanks for all your help
Just curious, what is the clearance between the OD of the counter gear spacer tube and the ID of the counter gear bore? Once assembled, the counter gear shaft can never touch the tube because it rides on the needle bearings, correct?
Yes correct. The Muncie tube ID is a little over 1"
The shop manual for the 1963 Studebaker Avanti shows the T-10 4 speed needles and spacer washers in the countershaft in a different sequence. It shows needles against the countershaft bearing roller, followed by two spacer washers, the next set of needles and then an outer spacer washer. Does it matter or is one way better than the other?
The shop manual is wrong. The correct way is in the video
@@GearBoxVideo Over the past few days I did an extensive amount of research on this and finally found the answer. I reviewed the expoded views of earlier T-10's from many other makes and models and they all had the double spacer washers and no spacer washer agianst the countershaft bearing roller. The reason for this is that on the earlier T-10's the countershaft bearing roller was seamless. Somewhere along the way the T -10's and Muncie 4 speed countershaft bearing roller started to be built with a seam and the need for an inner spacer washer became a necessity.
Hello bro, pls what is the part number for front and rear bearing in a muncie m20?
N307LOE and 6308NR. We do sell these as well.
I just took apart an m20 out of my daughter's '69 SS el Camino and fond 7 of the spacer rings in the counter gear but, didn't see where the 7th ring was. If I install the 7th ring, the total bearing length is still shorter than the thrust faces.
There are only 6 spacers and when stacked sit below the thrust surface. Some rings vary in size. If you need to stack an extra stack it against the tube
@@GearBoxVideo Now you tell me! Will do, though. Thanks!
I can only seem to fit 18.. and it tried packing em in tighter. Iv taken em out and cleaned them multiple times. Idk what I’m doing wrong.
Pay attention to the size of the needles in the video. You probably have a 7/8 inch countershaft which uses less needles. You are doing nothing wrong.
GearBoxVideo I figured it out man. I’m doing a rebuild on a 1977 dodge d100. 4 speed. I didn’t realize u had to do them on both sides. I was trying to pack them all on one side and that’s why they wouldn’t fit. The mopar cluster has this groove that seats the washers/spacers. I didn’t pay close enough attention to the video. Thank u man!
good video question I am building a NP203 transfer case, when I put the needles in I get a gap in the needles when they are all in but this gap is cannot fit 1 more needle in. is this ok or will I have to force 1 more in?
No this is normal. That clearance remember is for all the needles combined. It's fine.
@@GearBoxVideo thank you very much for your input and time.
The linkage on a fact m21 m26. The trans old school but anyway. Lemme tel I bought a 71 olds 442 convrt back in82?3 but any way oh ya know what 70 :-) 72 you had to park the car in reverse. Colim lock.
What is your opinion on the Saginaw 4 speeds?
They are good light duty 4 speed transmissions. Not for HD use.
cool super video
Thanks
I have an m22 transmission I'm 66 and it doesn't want to shift into 3rd. however it downshift from 4th to 3rd with no issues could this just be a worn shift fork or a bad sync
Block out conditions are caused by bad synchro assemblies and poor clutch release.
So your saying its probable a bad synchro
A bad synchro assembly or poor clutch release.
Paul how can I order your book?
Thanks for your interest. Here is the link to order:

Where can I get replacement needle bearings?
I stock them ... Contact info is on my website listed in the video
GearBoxVideo I wrote the email off the TH-cam page.
Paul; I put my m20 together using a 1974 motors manual. On the counter shaft, it had the pipe spacer, then rollers, then 2 washers, then rollers and final washer. I just went back to my manual to verify and this is correct.
So to sum up the rollers are riding right up against the pipe spacer.
What do you think ?? Thanks
Set them up as instructed in the video. The manual is WRONG
GearBoxVideo Thank you Paul for your advice and quick response.
Have a great day.

Caged Needle Bearings?
I dont like them.... Reduce the load capacity by half
It looks like your gloves may be one size too big. They're not forming to your fingers.
I hate tight gloves. I rarely use gloves. Gloves don't last long-term
@@GearBoxVideo Understood. I made that remark in response to your comment early on about not liking to wear gloves because it makes the work more difficult, or some such. It looked like the gloves were fitting loose, which would add to the difficulty. Suit yourself. Thanks for all of the interesting gearbox videos.
Wait so if u go into a dollar stores with a dollar you can't buy anything because of tax? Should be like UK, all prices include tax.
No.. Vat in the UK is 20 percent. I would rather have them add the small 6 percent after the sale here.
@@GearBoxVideo yes, but that's not what I'm saying, its already included in the price, so i can walk into a Poundshop with 1 pound and walk out with an item. But you walk into a dollar store with 1 dollar nd u can't buy anything
I thought. . . surely he’s not going to use a a seamed tube for the countershaft to spin on. . . oops. My bad.
It's a spacer. Nothing spins on it. Split seamed tubes have been used in Muncie and T10 applications for over 50 years
GearBoxVideo : Yes, I picked up on that fairly quickly. I’ve built a couple of bicycle frames. . . from seamless tubing. But I’ve run into steel frames where, running my finger inside the head tube, I’d have that “Oh, Oh” moment. And so e of these frames were NOT cheap. Sigh.
Luv your stuff!
