NASCAR 4 SPEED TRICKS FOR A STREET 4 SPEED

[@AJGreen-cn8kk]

I've been working on everything from small engines to heavy equipment and street cars for forty years and I still learn something new every day. Thanks for taking the time to film this.

[@nadronnocojr]

Imagine if they still taught shop classes , this channel is my new Bob Ross.

[@Bigmike3406E]

This guy built my M22 drag special and it’s sitting behind a 496 big block with 800 hp now for about 3 years . Never had an issue still running strong shifting like new.

[@blueridgeboy6791]

What's the specs on it if I may ask. Just curious. Any modifications to the transmission?

[@GearBoxVideo]

Its a video on how I prep transmissions. Its general info in a way

[@ricardo1967]

Paul, I rarely comment on KZbin but I want to say I really like your videos, keep up the good work man.

[@AndysDogHouse]

You should comment on the videos that you like or that are helpful. The reason people upload videos is to help others. So you should show them that you appreciate their effort. Leave even a small comment. It's like a smile, it brightens up someone's day. Thanks.😊👍

[@davidmiller9485]

the fact that you do the extra work on the gears is a sure sign of a professional. I build mopar motors and automatic transmissions and it's the little things that separate the pros from the amateurs.

[@judges69]

Built my T5 using your book and guidance, best trans I have owned, still running strong at Mosport

[@tigerseye73]

I am totally impressed with your knowledge, expertise, and your video presentations. It cannot be overstated how much help you provide to your viewers. Thank you.

[@trafficczar3366]

When I was a machine tool operator at a B&S back in 70's I had the opportunity to work in the machine tool division gear section. I remember we used a machine that would shave the gear and then after heat treating I would hone the gears. Check them for run-out and all that then and not least I would match any two gears that would be mated by the amount of decibels they recorded in a sound proof booth. There was a lot more to than what I am mentioning here. Your video brought back memories. Thanks

[@GearBoxVideo]

You are correct, that is how it was done in the old days. They hobbed, heat treated, and shaved, correcting for distortion. Now most gears are ground after heat treat and with CNC type machining, better alloys, and better control of heat treat, some steps are eliminated and quality and profile accuracy are greatly improved.

[@trafficczar3366]

Ah the good old days, I'm a dinosaur now.

[@Patrick-eieio]

I really love the attention to detail. Excellent craftsmanship and execution, as well as intelligent thoughtful explanation through the assembly. It's refreshing to see someone that's passionate about their work and committed to true quality. Thank you Paul!

[@wrenchmanhotrods1247]

I worked for GM dealers 1970 -80 and did more Muncie and Warner 4 speeds then I can count . Thought I knew a lot about them but you gust showed me some things I didn't know . Nice job , thanks . Don

[@hershaljones2907]

Excellent video. I appreciate you sharing your obvious years of experience. A good transmission man is hard to come by especially nowadays.

[@JC-gw3yo]

it is great to watch a man that really knows what he is doing...

[@mikes9939]

Beautiful piece of hardware. Love the idea of roller supported gears for the ultimate in low friction considering how fast some of them turn on the mainshaft just along for the ride.

[@peterjones6945]

Nice to see the improvements you do. Liked the comment about seeing a NASCAR box and knowing it would 'cross over' Thanks for sharing

[@eyesalooking]

Just received the first book from Amazon today. Been reading it most of the day. Great photos and explanations. I have a Tremec 176 and Dana 300 for a Jeep CJ8 and a Tremec 177 or 178 for a full size jeep so that is why I am interested in learning more about them. So far I have enjoyed all of the videos and some of the information is actually sinking in so there is hope.

[@jimpeeden2004]

Great books, so much info and accurate photos, the best way to keep our gear boxes shifting and shifting better. "SHIFT FAST!" Thank You Paul

Holy crow. This is the first of your episodes I have watched. Clearly got some backlog to go through. Wish I had access to this level of information back in the late 80s. Would have made things a lot simpler. Oh well. Cheers.

[@TractorWrangler01]

I really want to go through the gears on that box to see how its feels and how slick it goes into gear. Love your videos.

[@AverageJoesracingteam]

Great video. Thanks for sharing your knowledge. We are Road racing a Lexus sc300 with w58 . I've always focused on the engine and diff, assuming that the 5 speed was what it was. After watching this video I will look into aftermarket parts for the w58 to hopefully make it smoother and more reliable. Thanks

[@jonjones-v5d]

Great vid and camera work, as usual. I watched the vid to see how the same techniques apply across the different gear boxes. THX!

[@allenlane5018]

This was another great video. I love all the technical info. It’s so great to see someone so passionate about something. The pride you show in your work is second to none. Can’t wait to see the next video. Hopping for a road race t5 because that what I’m getting ready to build.

[@GearBoxVideo]

I already did a T5 road race build.. please look at other videos on my channel.

[@zwild1160]

Learned a lot just watching your videos. If I ever need a 4 speed box I know who to go to. Your video presentations are excellent.

[@mickcoomer9714]

One competitor, some years ago, in a Ford Sierra which came with a four speed 'box only in the BTCC ( British Touring Car Championship) ran a five speed 'box all season. He got away with it 'cos he’d got a four speed gear knob on.

[@Michael_Lorenson]

Fascinating look at one of the ways 'stock' road racing cars are prepped in subtle but important ways. In addition to the improved cooling, reliability, and shift action, I'll bet this procedure is worth about 3-5 hp when the gearbox internals are really spinning up a storm in there. Thanks, Paul.

[@GearBoxVideo]

Glad you liked it

[@FrequencyOfThought]

I learned a lot from your videos. Thank you for sharing your wisdom in gearboxes.

I really enjoy your videos and have allready learned a lot from you. I appreciate what you have done only wish I had found it sooner. I will be purchasing your books soon.

[@glennwmurphy1]

YOU HAVE SOME THE VERY BEST TEACHING TECHNIQUES!

[@wysetech2000]

Love to see the master at work. How long do these transmissions last before a rebuild is necessary?

[@GearBoxVideo]

Really depends on what the team does. Usually after a season they may tear it down and rering it

[@yafois988]

I can tell right away we would be Far better off just having it done by you, sparing ourselves the "experimental process” grief, and upgrades you have conquered ! Thx, this was a very good video , informative for simple DIY yet again, I would just have you do it and so it gets done just Once, & right!!!

[@johnrobinson357]

Paul you are a master. Huge respect for you sir if you recommend it i am certain it is very good. Once again top notch content.

[@AmerIHCan]

Always looking for ways to eliminate drag and heat (as well as vibration and noise) when it comes to my `73.5 International Scout II. It's a 4200# truck w/aerodynamics of a brick! LOVE my T19 and sure would like to add to its lifespan of possible. Don't know much more than I'm never using anything but GL1 in it, so gotta ask, can this trick be performed on an IH T19? Any chance the upgraded shafts are out there or what's an estimated price to have it done to the shaft and who* would do the machining? The PTFE coating has me wondering about differentials as well. When I was 15, I learned the 5 HP trick for painting under the valley pan so oil flows smoothly. Only makes sense. Thanks for the awesome demonstration!

[@GearBoxVideo]

The coatings and polishing do help. You can drop another 1000 dollars doing it

[@mattcaser6581]

And thanks for the link on your books too. Just ordered one of those, looking forward to going thru it page by page.

[@stottpie]

Paul, you have an eye for editing. Love your videos, and my T5 (with your 5th speed Sebring gear) is running great now. I wish I didn't have to pull the transmission back out after my speedo drive gear got unclipped, but your video and book helped me through that. Big thanks.

[@henryjewell3900]

Absolutely totally blown away by what you do with 4 speeds.

[@therealspixycat]

You could use the new hollow shaft to constantly provide oil to all the gears or rolling bearing just like you would do on a crank shaft. It would also be interesting to see how well the synchro rings match with the gears. And is the tiny needle bearing sufficient for the lateral forces on shorter gear shaft? Thanks for the very nice video

[@GearBoxVideo]

Actually most automatic transmissions use pressurized feed oil thru hollow shafts. It's all been done before. Problem is you need to run a pump system. These old transmissions don't have any. Most of the newer manual transmissions and some older ones we convert run speed gears on rollers. No issues.

[@2bziggy]

I have a 6.3 liter 383 cubic inch fully forged stroker motor what type of transmission do you think would work for me

[@funnelspider]

great video love the time and patients you put into the parts you make .. and yep every little detail counts

[@dukecraig2402]

Nice, I haven't messed with a lot of car transmissions (although I had a super T-10 I bought for a 73 Corvette I had) but I set up a lot of Harley transmissions and for the last 11 years I've been getting into setting them up around road racing standards, I've been using an electrical insulation paint to coat the insides of the cases to keep the lube from wanting to cling to the inside of the casing, I'm gonna check into the Teflon coating trick, where do you send yours to for coating?

[@t5montecarlo]

Thanks for the lunch-time tutorial, Paul. I love how you share your knowledge.

This was really informative and I'll do my best to apply these lessons as much as I can.

[@Eric2300jeep]

Love this channel of yours Paul! Your skills at working on transmissions and your ability to explain things in simple to understand context, is fantastic! I didn't find anything on your channel about NV4500's though. The one in my Dodge Cummins is giving me some issues and I'm planning on rebuilding it. Would you recommend staying with the factory style carbon fibre synchros or switching over to brass? Appreciate it if you can give me any feed back on that! Keep up the awesome work!

[@GearBoxVideo]

Always use the carbon rings since the gear cone angles are designed for them. I would suggest not using the Amsoil but the recommended Synchromesh oil.

[@Eric2300jeep]

good to see you taking the time to go into depth!!

[@idaho2ndgens240]

Great video! Learned a ton from you. On the box you described with the different main shaft, rollers, etc. what HP/torque would a box like that withstand for some road racing?

[@GearBoxVideo]

500 hp Max. For the 500 to 800 range the Muncie spec 25, which has similar treatment

[@Ademann]

I like your videos! They bring me back in my motorsport time! Thank you!

[@joshcosta423]

Can some of these tricks be applied to other manufacturers of gear boxes? Say like a VW type one trans? Even say and engine block/case? I'm primarily referring to REM coating gears of the trans and Teflon coating of both cases?

[@GearBoxVideo]

Yes. There are many units with these treatments. See my PRISHOW videos

Nice to see you again Paul, great workmanship as usual.

[@renegadeR75]

[@BMBEYC]

great video! I ordered your book, thanks for sharing your expertise and videos. you mentioned you wouldnt use this setup on street? why?

[@GearBoxVideo]

In general it's not needed and there isn't much of a gain versus the expense.

[@madmanmechanic8847]

Great video very informative . Congratulation on your two new books ! I have a very rare AMC T-10 that I bought at a wrecking yard . I haven't pulled the side cover for it yet to see the condition of the gears but had a couple of places that do manual trans tell me the trans was built by Borg Warner for AMC at their specs the standard T-10 gears wont work if I can rebuild it and restore how much do you think I can get out of it? Looks to have the original shifter for it also the handle is gone its date coded for 67 and 68 would of came out in the AMX'S what they told me off the tag for it. Keep up the good work ! Thanks Roger

[@GearBoxVideo]

These are 1st design ST10 transmissions. We have many parts available for these.

[@dgretlein]

Great stuff but for the next build, please demonstrate how you drop the gear shaft assemblies into the case. Somehow I think that is where the “knowing where to tap with the hammer” knowledge is. Thanks!

What would the power handing be on this setup? Im looking for a suitable 4 speed gearbox for a chevy monza with a 450 hp 350 and under 1200kg to be used for road racing, I dont know whether I should go for a muncie (probably the close ratio, heavy duty 31 spline version with the 2.2 1st gear) or a suitable T10 I could put together myself to keep costs down? .. Or do i must try to find a cheap nascar cup 4 speed and not worry about breakages very often if it all?

[@GearBoxVideo]

Go with a used cup 4 speed or a Roltek T10

Not much more HP then what they were rated for. Behind a 400, probably the gear vendors OD is a proven and better choice

[@4speed3pedals]

Just recently attended a webinar about Teflon seals. I don't know if a Teflon seal is available for the tail shaft of either the Muncie or the T-10/Super T-10. If you could swap over to them it would be a great improvement. Teflon seals are installed over a dry shaft, the seal area would be cleaned of any oils where the seal rides . An installation tool is recommended to get the seal on straight. The Teflon seal actually transfers particles from the seal to the shaft filling in any minuscule voids in the shaft and the life of the seal goes way up. Best thing is that after the seal laps itself in, the seal dimensions never change so a wear groove is never worn into the shaft. If the shaft is oiled during installation, the seal may never seat or take forever to seal. . Thing is, does National, Chicage Rawhide and other manufacturers produce Teflon replacements? .I have been using Viton whenever possible vs Buna N and the results have been excellent. Thanks for posting all this info. I love the polished gears and the Teflon coated case interiors. My 2 cents.

[@GearBoxVideo]

They don't make Teflon seals for extension housing applications. You have to be careful with Teflon. Unless you are using hardened components, teflon seals will actually eat up the yokes and shafts they run against.

[@DebbieBaumann]

" I need a solid box that is going to be maintenance free....." Chuck, everything in racing requires maintenance. I'm no longer building transmissions at this time. You may want to try Roltek transmissions.

Some gears are ground, but grinding can only be accomplished if the clutch teeth are not in the way. Gears are shot peened then super finished. You don't tumble racing gears.

Also opinion on higher torque slower 351, vs higher speed 302, which will gearbox hold up better?

[@cconnelly2385]

Forgot to say thank you Paul!

[@josefkrakel9136]

Question about teflon coating: teflon is not a good thermal conductor. Does coating the outside or inside of a housing adversely affect cooling by inhibiting heat flow to the housing or from the housing to the air? I wonder about this as teflon coating outside on oil pans/blocks/etc would help prevent grease and road dirt from adhering (which would act as a thermal insulator) and inside would help oil return in oil pans and valve covers. Would the benefits outweigh the loss of thermal conductivity due to teflon not being a good conductor?

[@GearBoxVideo]

As mentioned parasitic drag or drag (in physics) causes heat and friction robbing horsepower. When oil clings to both the case and gears as it gets pulled apart heat is generated. The outside is an added benefit of easy clean up. Similar to painting the inside of differentials and engines with Glyptal. Essentially you've created a non stick surface for the oil.

[@danielsimpson8929]

@@GearBoxVideo does the coating last the lifetime of a transmission? Understandably the load and use of the transmision may vary greatly.

[@GearBoxVideo]

I've never seen it come off unless you scrap it. Similar to what a Teflon frying pan has
