1961 Corvette T10 4 Speed Transmission Upgrade

New parts to convert your early General Motors T10 4 speed cases to use later Super T10 gears. Use your existing case or new HD main case.

[@TheEZGZ]

Great Job. I am always amazed that new modern parts are created to upgrade these old classic Hot Rods like a 57 vette. There can't be that many around not to mention they have had there guts torn out so many times. I am also glad that there are new pushrod engines still being created to fit in those old cars. Might not be as high tech as overhead cam engines but they are so much better than the original. Nice that people like you find ways to upgrade those old trannys to take todays HP. I look forward to your next vid.

Thanks for watching

[@ArmstrongRacing]

That’s awesome. I recently did a similar job upgrading a 85’ Toyota gearbox with the nicer 2008 parts. Lots of fun

Learn something new every day. That mid plate is badassery !

[@t5montecarlo]

I was in need of a manual gear box fix; thanks, Paul, for another professional-quality video. The original T10 gear looked to be not much larger than a Saginaw gear.

[@alro2434]

Thanks. Worked on one, 61 Corvette, 50 years ago & it had a mismatch on 2nd gear, they were offset about 1/4 in., musta had a special bastardized gear set. Car had the thick 2 piece aluminum bell housing/scatter shield and the front brake's backing plate had duct holes with blanking plates & a fan blade on the hubs.

[@GearBoxVideo]

Gear sets never exactly were lined up perfectly.

[@BritishBoy1971]

What a clean and neat engine that car has, well done!

[@TractorWrangler01]

I always learn something from your videos. :-)

[@CORVAIRWILD]

Like usual, precise and to the point and just nothing to say but great video. I have a 62 Bel-Air clone 409 with t 10, it's worn out, and your video just added to the complexity of deciding what I'm going to do. I thought I could rebuild it, but like usual, nothing's ever so simple. Question is? Who do I trust to make sure it doesn't come back as a pile of shiny junk

[@GearBoxVideo]

True. Thanks for watching

[@wysetech2000]

Always well done, Paul.

[@BustedClassicGarage]

Love the videos man, they're always packed with great info!

[@Michael_Lorenson]

Thanks again Paul, I learned a lot!

[@unclequack5445]

Paul, You make me want to find something to install a Super T-10 into. Plus I wish I had your job , I've always liked gear boxes.

Loved this one, thanks!

[@montes3of3]

Paul, thanks for the vids. You often point out some differences between the T10 and Muncie transmissions as you build, but can you explain more in depth the differences and characteristics between the original Muncies and T10's of the muscle car era? Also, discuss the same in regards to the modern Muncies and T10's you build today with the new cases and upgraded parts available now. Thanks in advance.

[@GearBoxVideo]

Good idea. When some time frees up for me

[@shaunswanson7390]

Paul what is your contact info to purchase parts?

[@Hot80s]

great work.

[@FixItStupid]

Thank You !

[@RobertKohut]

Nice!!

[@allanturner5325]

Paul I have a 1965 cast iron case t10 with aluminum tail housing, 27 spline output shaft. From what I have researched it seems to be close ratio with high nickel gear set, 7/8 pin, is this known to be a fairly strong and if not is it upgradable, thanks in advance I enjoy your videos.

[@GearBoxVideo]

Yes they are nice units

[@Texassince1836]

Speaking of 833s, do you have any knowledge, tips, or tricks you can share about the NP833 OD found in some 80s Chevrolet trucks?

[@GearBoxVideo]

It's nothing more different other than a gear ratio and impossible to find replacement gears. My book does do a picture by picture rebuild on it

[@bk-yg9yw]

What 4 speed do you recommend for a sbc 383 stroker with about 450 to 500lbs of torque it'll be going in a 65 chevelle Malibu with 373 rear gears and street tires on the 14 inch wheels

[@GearBoxVideo]

If you can get a new M22W that would be perfect for that application

[@robertmackie5062]

Great videos . Rebuilding t 10 1959 tranny. Will super t10 torque lock slider work better than old t10 sliders? Is there a big difference between 27 or 25 tooth in 4 th gear input shaft?

[@GearBoxVideo]

ratios yield different tooth counts.. Locking sliders are usually needed since those transmissions were prone to falling out of gear.

[@f150bft]

I have a T-10 in a 64 Fairlane I just got. It's not original to this car. Is there a T-10, a 1st design Super T-10 and a 2nd design Super T-10? Anyway I can downshift to 3rd ok, and sometime to second....but I have to be close to stopped to go to first. Also it will pop out of second and third if my hand is not on the shifter. Hurst shifter. Any thoughts? I figure syncros are bad but it doesn't scrape changing gears.

[@GearBoxVideo]

The gears, forks, and sliders wear causing falling out of gear issues

[@unclequack5445]

Paul is that plate your design? It's a full CNC billet machined piece right?

[@GearBoxVideo]

Not my design. Made by Richmond Gear. Full 1 piece billet.

[@andybuza1736]

I have one of these were they ever put in 72 Chryslers the guy told me it was a rock Crusher for a 72 Duster but it has the 9 Bolt side plate and the 3 shifter cable what have I got

[@GearBoxVideo]

No that's a New Process A833

[@TheRoguelement]

I'm all for better quality parts but will I ever feel the difference between factory parts & billet parts Or how can I justify the cost .. ????If I sell a customer billet everything how will he benefit to justify the cost ?

[@GearBoxVideo]

The parts we make out of billet you cannot get new anymore so your point is not valid. Most mid plates and covers are worn and actually making them out of billet makes them stronger than a cast piece. These parts are not for everyone so you can always replace them with used stuff if you're not interested in a performance transmission

[@brianlawrence2922]

Hi Paul....When ill the side covers be available ....And cost..Please .

[@GearBoxVideo]

They will be posted soon. I need to test a few things

[@rogerjustice8835]

Can I make a request for a nv4500 tear down and rebuild.

[@GearBoxVideo]

Please see www.5speeds.com/requests.html

[@mustangperry1469]

Hi Paul you need to hit Junkyard Doggs up i told him about your mustang t5 kits and that cluster support plat you have

[@GearBoxVideo]

Who are these people?

[@mustangperry1469]

i just watch there videos and i hit him up and told him about your videos he rebuilds t5 trans and i noticed he didnt put a cluster plate like yours on it so i gave him your web site. love your videos i have learned alot, thank you

[@sickassdan5556]

Can I use a t10 case on a super t 10 if I bore out the counter shaft hole to 1 inch?

[@GearBoxVideo]

The thrust surfaces also have to increase in width .030. It's not also a 1" bore. You need the countershaft first to measure the offset for a press fit

[@BritishBoy1971]

I was wondering if anyone had had my problem, with my VW New Beetle 1.6 engine/manual gearbox?... When changing from 2nd to 3rd gear quickly, when accelerating hard, it crunches very loudly (it doesn't do this when driving slowly and when taking time to change gear). Would a gearbox oil change help in any way?

[@GearBoxVideo]

Probably a bad synchronizer

[@BritishBoy1971]

GearBoxVideo Thank you, I'll look into that. 😶👍

[@unclequack5445]

Yeah it will help but sounds like you have something damaged in the gear box.

[@BritishBoy1971]

Uncle Quack Thank you. Apart from the crunch noise when changing from 2nd to 3rd it runs well. I am very conscious of it, so quite often get up to speed in 2nd, then go straight into 5th.

[@unclequack5445]

Rottie Sooner or later you will have to pull it out and repair is proper, lucky for you its usually easier and less expensive to fix a gear box than an automatic trans.

[@paigeyyc]

do you know how to fill the overdrive unit?

[@GearBoxVideo]

Fill it to the level of the fill plug!

[@robertcolson3637]

Who can do these conversions in Ne-Co area?

[@GearBoxVideo]

It's a speciality. The transmission needs to be ordered

[@Fosgen]

What oil was used to fill this gearbox up?

Driven Racing GL4. See www.gl4oil.com

Hi sir i am one of your subscriber youtube fun can you make or build transmission like a R. 2. 4. N. 1. 3. 5. Comvert on motor engine please

[@GearBoxVideo]

No. I do not work with Automatics

[@davidmiller9485]

@@GearBoxVideo if he's asking if you can get an automatic to shift that way, hell no! the clutch packs (depending on the unit) are set off by a computer. If he's referring to gear indicator on dash/above the steering wheel, maybe but it wouldn't be worth the work. ( i do rebuild automatics) :)

[@CORVAIRWILD]

I was at a car show swap meet in Springfield Mass, and the guy was vending manual transmissions and such, and I mentioned that I watched your videos. He had nothing nice to say about you. I watch your videos very carefully, and this guy obviously had a grudge... maybe you were winking at his girlfiend or something???

[@GearBoxVideo]

Have no clue who it is. I use to do the eastern states show years ago. I sell to a great deal to pro builders. They buy my parts because they fit, are correct and have a high quality. Most of the people who have a grudge would rather buy bad parts. I really couldn't care. There are always haters.

[@CORVAIRWILD]

@@GearBoxVideo I guess I could stir the soup a bit, I did take his card, it's somewhere around here. On a more positive note, the T10 in my 62 clone Bel Air 409 425 is worn out, and after watching a bunch of your videos, I'm sure the 2nd gear Synchro is not gripping. But as you've explained quite clearly, there's more to rebuilding a transmission than throwing a bunch of eBay parts at it. So if I had my druthers, I would convert it to a five-speed Tremec like my other 62 Impala 409 clone, but I don't have the money, nor am I in love with the car to spend so much money and time to move the crossmember etc etc. In my next life, when This Disaster is over, I wouldn't mind bringing the transmission to you in Florida, and we can make a video together. I have lots of subscribers, you could look me up. It would be fun, and I have a very good friend in Florida that I'd like to visit. On another note, or changing gears lol, I used to have a 1977 Chevy C60 dump truck, with a Clark 5-speed. That thing made such great M22 Rock Crusher transmission noises! Could I build a Saginaw with straight cut gears? Or rather could you? Or maybe an M22, but wide ratio, so I can beat the crap out of it and not worry about breaking the T10? There's something to be said about paying extra for a car with no power again steering or brakes, and mechanical lifters that you have to adjust. The thing is so loud and obnoxious, but that's the whole fun of it, isn't it?

[@picardokavin7889]

I mean sir manual transmission ....

[@GearBoxVideo]

You cannot change the shift pattern of a manual transmission without redesigning the entire shift mechanism externally as well as internally

[@t5montecarlo]

@@GearBoxVideo It looks like he is describing the shift pattern of a T50.

[@GearBoxVideo]

Could be. Now that I think of it. But you can't convert transmission shift patterns and that is what I believe he is asking.

[@madmanmechanic8847]

I wish you hadn't skipped putting it together . You're videos are usually pretty good but you sure left a lot out

[@GearBoxVideo]

Because there are other T10 videos. Stop complaining and actually take the time to look at the other St10 videos... The video shows the mods

[@madmanmechanic8847]

@@GearBoxVideo All I seen was the Super T 10s they are a different design and require different tear down and reassembly than a standard early style T 10 I have a 63 I need to rebuild . Am I wrong? I haven't tore one down in a long time.

[@GearBoxVideo]

The transmission in this video is a super T10. The video is about converting an early T10 to a Super T10. Rewatch the videos and take the time to watch the ST10 videos. The video IS NOT and early T10 video. It's about mods you can do to make an early T10 into a Super T10. My point about my reply is that you jumped to a conclusion without really watching the video and taking the time to perhaps read the description of the video which specifically states about making upgrades. If I do rebuild videos they are titled correctly and detailed with both tear down and assembly. I don't have an early T10 video on this channel but they are covered in detail in my book.

[@madmanmechanic8847]

@@GearBoxVideo Ok so different tear down and procedures on early T 10. I understood what you were saying about the upgrades I didn't jump to conclusions . Thank you for the reply .
