The single most lovable detail about your productios is:
No background music!
Nothing beats the pleasant clicking and dinging of metal parts joining together
Thanks!
Yeah this kind of work has its own soundtrack, you don't need to blast over it with techno music.
I agree. All these do-it-yourselfers who try to be movie producers with the music soundtrack and all.
I completely agree. And excellent content, well done!
In "Zen and the Art of Motorcycle Maintenance " Robert Pirsig says to never trust a specialist shop that is playing a radio.
So true!
Best bit? When that circlip shot off across the workshop. Because we all know that pain.
Who is this guy? How is this possible? Unbelievable skill, talent and knowledge.
Hats off to you 🤠
Haha thanks! That’s very kind of you!
And plus he's a handsome young guy, we can be jealous 😄👍
I don't deny that he did wonderfull job, but calling it "unbelievable skill, and knowledge" is just stupid. Or just you are such a morron that dissasembly of a transmission for you requires "talent". It is just combination of equipement and bit of knowledge - that's all.
Andrzej Strzelecki wow, so rude, such arrogance. You got issues?
I’m a long term and good mechanic, but I can respect good mechanical skill. Chill out man - it ain’t going to get you anywhere.
Show Jethro the respect he deserves
@@AndcRew14414 You stink the jealousy...😂😂😂😂😂
Let give a cookie to this poor little boy, he is crying......🍪
I've watched lots of car restoration videos on RUclips, but I can't ever recall seeing a gearbox being stripped down and rebuilt like this. Thoroughly enjoyable to watch!
Fantastic video mate. Gearboxes scare me with 1000 parts that all look the same. I would pull it apart and never get it back together again. Good to see the circlip flying across the workshop. It reassures me that you are still human ;)
Home Built By Jeff Hahaha. Oh man there were so many of those moments that I didn’t get on camera.
I thought I was the only one that had circlips flying across the shop. If you were deaf, you'd be hard pressed to find it again.
@@JethroBronner
I'm reassured I'm not the only one having those clips flying around !! Not to be found in my messed up garage, of course.
Beats me why this channel does not even have 9k subscribers. Everything is nice and tidy, presenter knows his stuff. Editing is spotless. Narration is kept to bare minimum, obviously by choice and not accident. I would not be surprised if this channel had 90k subscribers or more. It has all the qualities, But it has 9k. What am I missing?
Jon Remmers I need to be more consistent with uploads.
Someone else with a deep passion for old Italian cars, beautifully presented in stunning videos? LOVE your work, my friend!
Miller Corner Thanks for the support man!
I am amazed at this guy’s knowledge. He operates like he been doing this for 40 years.
His training must have been intense.
Yes. Understood. The shop is spacious, and has all the tooling for this kind of work. The hydraulic press. The bead blaster and all of that. Very comprehensively tooled up. As is the rather young man who is doing the work.
Brings back memories of my 1970 GTV 1750. Kept it in my garage for years intending to fix it up, but finally sold it to another Alfisti who had several cars, plus a workshop and tools. Bravo for taking on the task of keeping these automotive jewels running.
My fix for my 105 GTV 2nd gear crunch was to take sychro ring from 5th, and put it in 2nd. (Teeth ok.) Going 4th to 5th was dropping revs, so zero crunch. A successful freebie.
That is a good idea. I’m going to do that with my Giulia Ti gearbox next.
@@JethroBronner The Synchos work in pairs i.e. one ring for 1/2, one ring for 3/4 and one ring for "5". If you move the 5th gear synchro, one side has never been used !
My hat is off to you. May the day come I have a little workshop with a few Alfas dotted around to dote upon.
This is my kind of video! No flashy animations, no music, no redundant talking, subbed! And great looking work, that's how I'd want it to look after a rebuild for sure, looked like new bolts too.
I'm glad you like the style! All the bolts were cleaned up and electroplated because you can't get replacements 8x1.0mm bolts these days.
I am so happy that someone finally made this video, end extra happy since it's you with the production video that this adds. A very essential classic Alfa DIY
This was like a gardening for gear heads. So calming. Much props for nice footage!
love these cars!..they were made near my home, it's nice to see people around the world still loving them..
Very impressive. Looked like a brand new gearbox
18000rpm And hopefully it will shift like a brand new box too.
As someone with absolutely no mechanical knowledge I kept bursting out laughing at your GENIUS ! Now I'm hooked ! Brilliant !
With due respect to the beautiful DOHC Alfa engine, the transmission is probably the most involved and critical part of the mechanicals of an Alfa or most any car with a manual transmission. I was surprised to see that you didn't lighten the gears while you had them out. We lightened the gears on my 82 Alfa Spider and it made a wonderful difference. Super smooth, easy shifting, especially 2nd and 3rd; and 4th and 5th are like butter now. It's something Alfa should have done at the factory. Also, 9:36 is a great shot of the of the working business end of the trans. I loved watching all the new and cleaned parts go back together. It's a part of the work that I enjoy the most.
So it was a worth while upgrade? This gearbox was for a very factory correct car, but I’m doing another box soon for a more modified car, might try lighten those gears.
@@JethroBronner Yes, it was worthwhile. I have owned many Alfas and they all seemed to have a weak or damaged 2nd gear syncro, sometimes 3rd too. So, it was a whole new experience with a lightened gear Alfa trans. You can actually shift it pretty fast with no chunk or grinding or heavy resistance. It just feels so much smoother all around. If you lighten your Alfa trans gears, please do a video of it because it's very interesting to see it done and what is involved. You'll love it, no two ways about it.
Why is this so enjoyable to watch? Nice work Jethro Bronner!
That was absolutely beautiful. No other way to describe it.
It's very generous of you to take the time to make this video. Very enjoyable to watch. Thank you for sharing!
Wow...intense tranny...I am well versed on an old Saginaw 3 speed with O/D...took it apart and rebuilt it 3 times...finally on last overhaul needed a new freewheeling sun gear hub...found a great used one...got a small parts kit and did it all...wrecked the 55 Chevy for the last time...sold it for $550.00...it had 1 burnt valve too...I put over 300,000 miles on that 150 2 Dr wagon...my Dad bought it late 55 for $1,600.00...drove it 100,345 Mike's overhauled the engine and it sat until he gave it to me...Thanks Dad...RIP...
That level of know how just impressed the hell out of me.
Great video.
The only thing i don’t mess with, gearboxes...you’re a very smart lad
Clearly I'm a Nerd, best quarter-hour I've spent in ages (See admission of being Nerd) - I hear some people watch RUclips videos of people opening boxes etc, now if they watched someone opening up a GTV box, now that I understand! Good work Jethro! Would like to see the same done to a GTV6 trans-axial :)
One trick we used to do is swap the 1st-2nd with the 5th-Rev shift sleeve. Saves a little money on the rebuild. At least the first go around.
The only thing you have more than Alfa's is Seiko watch straps, almost as if you're a car mechanic by day, and a watchmechanic by night. Love your vids man keep it up!
ItsMeMakz I do have a lot of NATO straps for my Seiko. Thanks man, I’ll keep the videos coming.
ItsMeMakz , saw that.
Orange to green! 😎
I love seeing old Italian mechanics. Great job on your work!
Gearboxes never cease to amaze me.
Little late to the table here but WOW. Fantastic video. PLEASE let me ship my gearbox to you. I'll pay to watch you rebuild it lol
Aaaahhh, the sight and sound of Italian four-pot in-lines.
I have toured many miles at the wheel of (at different times) a Giulietta, 124S and 132.
Had a mate with an Alfasud, with whom I spent glorious afternoons blasting up and down side roads. Another mate had a GT 1600. Short fling with a girlfriend who loved her 1750 Sprint. Had a weekend dalliance with the newly-released 156.
This symphony of tools here, and your previous, the 1750 seized engine, casts me adrift on a sea of poignant nostalgia.
The sounds and smells of engines and happy hours in the workshop come flooding back.
I have dismantled a 124S and 132 for repaint. While the 132 was bare an engine service required re-bore and outsize pistons.
1592cc to . .what . . 1750 . .?
In a lightbulb moment I had a 'shop make header pipes and clean up the inlet manifold.
To complete the ensemble a ZF 5-spd replaced the 4-cogger.
Went through a lot of brake pads but them days in the twisties was f-u-n. Anyhoos, you could say I had a love affair with what many call 'Italian trash'.
Now, thanks to you, I want an Alfa again.
"NERRRRRRRRRDS!" - (Revenge of the Nerds 1984). Calming, mentally stimulating video of a gearbox rebuild. Thanks Jethro, keep rocking it.
Will do man!
Well done ! Gearbox repairs are very tricky. 👍
Yeah I had a couple of things come up on this, but it went together in the end.
fifty years ago i did the same to a '61 MGA gearbox. interesting in that i KNOW i didn't have a press, and yet i replaced the mainshaft and all the synchronizers, a few selectors and some other things. and had it completely dis-assembled. i suppose my memory may be failing me and had hired out a few pieces to be pressed on and off. anyway...
i remember at the time thinking the gearbox was a marvel of clever engineering and reminded me of nothing more, with all the springs, pawls, hidden ball bearings and woodruff keys, etc., than one of those wooden cube-like wooden chinese puzzles with a "secret" piece that moved, thus revealing the method of disassembly. :)
Excellent stuff, great mechanicing, using everyday tools or home made specialist tools - just wonderful!! Oh & great production to boot focussing on the details with no melodrama - simply wonderful.
Bravo, same passion I had when restoring the syncros on my D83 Swedish sure-grip suck machine. ruclips.net/video/FTzVW82FaRs/видео.html A classic for sure.
Excellent video ..my only concern was that you assembled it dry ..A good insight to those who do not understand gearboxes and that they are not as scary as they look
Still scary
I just can't get over how good your content is. Clear, concise and really enjoyable to watch. I only have old mini coopers and I am here just watching learning about Alfas! So enjoyable.
Hey thanks so much man!
7:21 - BOOM, headshot...
Great vid, mate! Gearboxes are somehow like a taboo to many mechanics, while in reality they're so fun to play with.
This is awesome. Had to rip up the console of my spider to diagnose a leak. This video helped a ton of figuring out where everything went. Much appreciated.
Totally amazing to watch this kind of wizardry, impressive indeed! How he knows where everything goes back is just astonishing. When I take apart a toaster to repair it there are always a few mysterious parts left over afterwards!
It's only something that I've learned recently. I was pretty scared to pull this apart to be honest.
@@JethroBronner I was scared just watching you do it.
I rebuilt one of these many years ago and I recall that the workshop manual said we should immerse the drive spiders into hot oil to make them slide on easily, we just warmed them up and pressed them on, like you, and verything was tickety boo!
I wonder if we will ever see the continuation of this series... Your videos are very inspiring and educational
Very soon. Thank you for checking in 👍
Fantastic. Yes love the no music, or the long droning face in camera droning on monologue we often seem to get when the subject gets specialised or nerdy. It’s inspired me to consider rebuilding my Alfa 106 gear box, I’ve done a couple of engines, but jethro has emboldened me to have a go at some thing I haven’t done before. Well done fella!
Watched this while eating my dinner tonight. Great stuff!
After watching your video about freeing up a seized engine from 2 years ago, I applaud the improvement in the quality and editing of your content. I also add my congratulations for not feeling the need to mask the satisfying sounds of a workshop, with a generic muzak soundtrack.
The '60's Alfa Giulia was always my favourite car when I was growing up. It's frightening how stratospheric the prices have become.
So helpful. I am bringing my gearbox to a shop and the mechanic will let me look over his shoulder. This video really helped me understand so much. Thanks Jethro!
The kind of video I like to see when I get up. Pares well with coffee, also. My Alfa's gearbox was supposedly rebuilt, but the guy only put in a new syncro for 2nd gear. The rest he flipped around between gears and used the opposite sides of the syncros. 3rd and 5th I think. I would have paid for all new parts, but he didn't ask...first gear takes a while to slow down when shifting with engine hot. Still, it all seems to work OK, better than before. I just wish that it shifted like a fresh Getrag!
There's nothing wrong with flipping the synchros if the one side is completely un-used, doing all new synchros would ad about $400 to the cost of a rebuild. Only changing the synchro isn't always enough, sometime you need to do new synchro operating sleeves too in order to get a smooth shift.
Thanks Jethro, I feel better about that now. He didn't replace the input shaft bearing though- assuming there is one on this Alfa- and while idling with clutch disengaged it's noisy. New TO bearing, so it's not that I don't think.
So satisfying to watch!
Nice work good to see someone using every day 'stuff' to assemble instead of using tool number xxxx at great cost.I mean using sockets & wood .
Cool shop, cool character, cool cars; I'm surprised you don't have more subscribers, you've got my subscription.
Sean Whatstone ah thanks man 👍 I really appreciate that
Great work Jethro! Quality content as always! Great insight to the gearbox and some of the work involved.
I will be replaying this many times. I've owned a 115 Spider for years, owned it twice and brought it back from the dead. I have a spare trans and will be swapping it soon once I crack it open, change seals and inspect. I will undoubtedly rebuild the original and put it back sometime. Your video is undeniable the finest I have seen.
Thank you for your time and talent.

Beautiful work
Another great film, keep up the good work.
Very nice and detailed video as always. You did an amazing job rebuilding that gearbox!
Awesome job, fella - serious diligence! 👍🏻
Thanks for great video and being honest about having to redo when needed. Apparently this isn't your first. Great inspiration for the next generation.
Huge nerds, all meshing together on an awesome video, we dont even need syncromesh!
Wonderful, informative piece. Those castings are lovely. The works are lovely. What good fun.
Very cool to watch the process. 👍
its nice to see there someone still keep an old alfa living. in my country (Thailand) there're less and less mechanic who can fix them. nice to see your vids.
Congrats! Beautifully done. The work and the video.
Nice work with the gearbox on the Alfa. Owned a GTV 2000 many years back. Great car to drive.
The GTV 2000 is one of my favourites. I have a 73 GTV to build on the channel sometime in the future.
As good as new! Fantastic work - a joy to watch.
Glad you enjoyed it!
My friend with a '67 Giulia enjoyed it even more. He's having issues with his gearbox, and was thrilled when I shared this with him.
Your insights and contributions are most valuable, and very much appreciated.
Keen to try this myself having never even opened a gearbox. Your video although it doesn’t explain step by step, highlights that it’s not wizardry. Worst comes to worst if you get stuck you can take it to a shop to finish off
Amazing work! Well done!
Really nice work
I dont say this often on RUclips but thank you for this video.
Fantastic video! Just acquired 1973 Spider-USA with two spare engines and various parts for winter project. Never attempted to do. Great to see how it’s done properly. Cheers. RJ-
Always great seeing old transmissions being brought back.
I am so glad that you confessed to making mistakes and having to split the case again. It happens. I rebuilt a British Leyland gearbox that did not split sideways, everything had to be slid in through the ends, nightmare. I never did get round to fitting it, ended up selling it after the car it was meant for had long gone.
Great video, the circlip flying off brought back a few memories from my workshop days many decades ago
So satisfying to watch the gearbox coming back to life..well done.
That rubber transfer was still good !
Fantastic video You're Not Alone keep them coming
Excellent filming
Thanks Jethro. Done a few in the past, getting ready to refresh another. Your video does make it look easier than I have experienced in the past, but it is still something most people can tackle. The press makes all the difference! And I've had to split one open after rebuild a couple times, so no worries there. They always go back together pretty quickly the second time through!
Yeah I did leave some stuff out because this video would have been an hour long otherwise. I've done one gearbox without a press and I swore I'd never try that again, it's a real pain.
This time round I got it all buttoned up and then realised the reverse gear was in backwards, so it had to come apart. And then when I got it back together I found one of those little metal jelly beans for the selector shafts lying on the bench... But in the end it worked out. Went together a charm on the 3rd try.
this is a gem . Thanks for the amazing amount of time it must have taken. Also yes, thanks for not having annoying background music. good job. work of art.
Trevor Binford Thanks for taking the time to check it out.
Impressive work!
hey thanks man. Good to see you back in the comments section.
Nice. This brings back so many memories, and I am now going to do it again, you have inspired me.
Done it again. We in America love you.
Excellent mechanic great video good stuff.
Thanks for another great video 👍✨
You just saved me so much time and effort. You're the best!
Amazing skill you have, you made that look easy
Wow, awesome video and great work! Thank you very much for sharing! Cheers from the US!
I do old Datsun and Z-cars. I still cringe when I think of doing a transmission, manual or auto. Makes me want to finally make the jump. Great video
Your passion for perfection is overwhelming...
Don't know how I found you, but this Detroit boy is really enjoying learning the eccentricities of the Alfa Romeo. Great videos, and as many have said, no music necessary.
A great video and look at what I need to do to my 1971 GTV 1750's gearbox. Right now I need to double clutch with a throttle blip between for any gearbox action involving 2nd and 3rd gear. While it's fun from a hands-on drive experience, a gearbox rebuild is in my car's future. (And great clip of your drive from South Africa!)
Yeah I think it's time for new synchros. My 64 Sprint GT could shift into 2nd even when just started at -20 degrees. It's best to get synchro issues sorted out before they wear out the sleeves, which are about $100 to replace.
Excellent video Jethro,i wish you would restore a 1989-1991 Lotus Esprit SE (my favorite)from scratch like you have so brilliantly done done with the Alfas..
Thank you very much! But they're so complicated! I actually used to have a Lotus Mk7, which I sold to help finance my workshop.
Lovely boxes when they're just nicely run-in, effortless and precise. Some might find the lever throw a little long, but that was what was expected back in the day. Anyway, very nice job, but don't forget to put a "NO OIL!" tag on it before you put it away.
I find the really engaging and fun gearboxes to use when they're built right, a bad one can be a real pain. I'll make sure I fill it before I go down the road.
Impressive skill!
Excellent video
Awesome to see you working, keep up the great work! Looks like new!
Hey thanks man! Yeah that box came out looking really nice. Can't wait to see it in the car.
I am indeed a huge nerd. This was wonderful. Looking forward to more.
absolutely great video Jethro, I've really enjoyed all the videos you've made. Nice stuff indeed. Thank you for taking the time to share with us.
Thanks for taking the time to check it out!
Great video Jethro !
I have two Alfa's, a 1966 Duetto with a 2ltr high performance engine that I bought from a good friend who used it extensively in competition, mechanically sound but the body was in poor shape and I spent 7 winters restoring it, came out beautiful.
The one I owned the longest is my 1969 1750GTV, bought it used in 1974, still drives like new.
Anyway, what I was going to say is that the gearbox in the 1750 had a worn 2nd gear synchro, so I replaced it together with a few of the ball bearings, and have been using instead of EP80/90 gear oil I switched to EP75 synthetic, and that makes a lot of difference even starting out from cold in the morning.
Keep up the great work, love your videos.
Greetings from Canada
Your videos help to remove some of the anxiety -- terror, really -- I have about tearing into my old Alfa. Thank you for great content!
They're pretty simple once you start working on them. Just take baby steps and you'll eventually get through all the complicated stuff.
@@JethroBronner I grew up working on Mustangs, so working on a GTV6 is going to be a bit shocking, but I'm sure I'll get through it. :-)
Total nerd - you nailed it. I could watch those gears all night long. Very nice work.
Yeah I figured there would be other nerds out there on RUclips who like this sort of thing.
