04 MGB Four Synchro Gearbox

[giniyal]

can u please use a better camera???? 

[S4r0y4N]

Finally I know how it works;-) Excellent video!

[se7enHuss]

You're a cunt... Only m.g. A on YouTube and u didn't even drive it

[wigzateguitar]

can anyone tell me whats the use of the bottom section of the whole contraption? the gears at the bottom which are not shown properly ?

[recordsj]

I have a 1500 mg midget with the stick shift moving forward in 3rd gear on acceleration and backwards if deceleration. Any idea on why this would happen? I have the transmission removed from the car with the top cover removed. There is no movement in the 3rd gear to cause this issue at least. Any ideas?

[dadof7kids]

My son finaly knows how a gear box works, thanks :)

[7150285]

DOES ANYONE KNOW????? i've always wonder what've happen if u start off with high gear during a complete stop....is it gonna damage the engine?? or is it not gonna move at all? and whats gonna happen if u use high gear for low speed climbing

[videoruslan]

@7150285 ,

if you start with high gear, car will start moving very slow, or engine will shut up, and it could damage the gearbox.

[supremelove83]

@videoruslan high gear is the smallest one in the gear box and it couldn't resist the heavy weight of car to pull it forword from the static sitting to moving sitting so it will be very load on engine and could damadge this gear

[Sweetearthslug]

@7150285

complete stop:

1: Car will jump forward 1 - 2 feet and engine stalls, car stops, gearbox is put under high stress for a burst period.

2: By releasing the clutch slowly, it is possible to take of in 6th gear, but it burns the clutch, gearbox isn't harmed, clutch however wears out very fast .

Hill climb:

Engine loses RPM, car loses speed, at a certain point (+-10Mph in 6th) the engine will struggle, eventually stall, gravity will pull the car down the hill in reverse

[7150285]

@Sweetearthslug for # 2, Im taking about automatic transmission which i believe automatic doesn't have a clutch

[BrunoRaven]

seriously. this is the best explanation for "how gearboxes work" that i've ever seen on yt. even my dad that doesn't speak english understood this just by watching.

nice work!

[lekhank6106]

cam u also tellme abt automatic gear thifting like this one

[raunchyram]

cvb

[raunchyram]

beautiful !

[xfire7]

superb

[erwer66]

the only part thts hard to understand is when u switch to 2nd to 3rd

[Mogliz0rz]

@erwer66 Ditto. I want to see the mechanics of the actual gear switch process that the stick does.

[positech123]

Awesome! Thank you!

[burrowssj]

thank you for this video!

[COD5252]

@xX00SomeGuy00Xx LOOL

[COD5252]

experieNce counts GREAT WORKKKKKKKK

[santhoshreddy2009]

Thank you sir for your fabulous explanation on gears.... Your video have cleaned of all my confusions on understanding transmission systems

THANK YOU

[trewjohn2001]

Great videos John, thanks for taking the time out of running a business to make them.

[comosibrute1]

Great vid ! I have a 77 Triumph spitfire 1500 would they be the same gear box?

[XXXCitizenX]

GREAT VIDEO, thanks a lot !

[WHITEVOLK8814]

That´s very usefull, thank you. But I still have a little doubt left: if you press the clutch and then you change gears do they influence into the car in anyway? I mean if you are in reverse and you let your car roll forwards, is it any bad?? Of course when you press the clutch you disconnect the engine from the gearbox but you don´t disconnect the wheels so...

[salemcripple]

@WHITEVOLK8814 In answer to your first question, no. You've got the momentum of your whole car behind it (thousands of pounds), so if anything the car influences the gear change (as far as gear speed goes). And your second question, no again. Because if you're in reverse, with the clutch pressed in, and you let your car roll forward, it's just turning the opposite direction. But since the transmission isn't connected to anything, it doesn't matter.

[WHITEVOLK8814]

@salemcripple So the only problem is connect the transmission to the engine (in R rolling forward) , because they turn in different directions. Now everything is clear. Thank you for your answer. Cheers!

You should be able to process more information when your stoned [around 3/4 times as much as when sober] which is why stoned people appear slow. They're simply smater. If weed makes you stupid, maybe you shouldnt smoke it, stick to alcohol. Anyway, you cant expect to learn outright from a video, go do some research if you want to learn about gear ratios/boxes etcetc I'm high as a kite and im also a mechanic, it's not hard to understand this.

[s14sr]

Well done video. I thoroughly enjoyed it.

[EXTREME4YEARSTOCOME]

cool name the names twist john twist

[shebz119125130]

great vid but can someone explain how the spline works?

[arisfuntas]

guyz could someone give me info for gearboxes. i need info for my colegue project.any info, links.

[transPlanko]

you know your stuff, great explanation, now I can talk to my mechanic with a bit more confidence.

[cellophanehk]

very good! thanks!

[indianvb]

Very nice : Thanks for information :) Post some more good stuff

[centromatic89]

John, how do you remove the nut at the front of the gearbox behind the clutch? its impossible to get a spanner in there and i dont think they make sockets that big?

[pheni0x]

umm i believe they state it should take 30 wt not 20/50.

[theiamania]

Really good explanation :) Now I know how a gearbox works

[lezorba]

thanx,you the champion.

[FanGunk]

Good job John!  5 stars~

[lucashc2]

Who invented the Gearbox is surely a genius!

XD

[kdkinen]

COOL thanks, this has always mystified me :)

[hypa7mach28]

greatly explained and clear u get 5 / 5 from me m8 keep it up

[hyperm0d]

Great video. The only thing is that in the beginning you say "when your foot is OFF the clutch, this is all that is turning". Right after that you say the opposite. I know what you mean but some may not...anyway minor detail but great vid and great service you are providing. Thanks.

[2009jimmy2009]

very well explained, still not 110% sure on how the synchromesh works but great video!

[fabaobao007]

thanks..good that is great mechanic lesson

[xxjacklivesherexx]

well done mate - great vid - i havent searched ur vids yet but wouldnt mind hearing you explain how a clutch works?

[WindsurferCascais]

Hi, it was a great mechanics class! Thanks for the effort and for sharing that knowledge on to next generations.

I'll be looking forward to see some more of your videos here.

Best regards!

[Kadaczech]

Yes,it's very interesting video,but I am Czech amd I don't understand everything:(

[skaterdudesmallj]

thnx alot i could awnser my q by listening at watching ur video you rock:P

[bionichb]

great video

[cwiqa]

it's very interesting thanks

[Heckvaalhagen]

A perfect video, and it is more perfect for my mechanic engineering class presentation this week.

Thanks :)

[Meex1989]

Damn, this guy can really explain how manual transmissions work.

[knouh2]

the best video informative, Thanx

[artofwheels]

great and informative vid! 5 stars

[GMforlife90]

you should be a dam teacher

[BestestMoron]

Excellent video... I am an electrical with no mechanical know-how and I understood pretty much everything... I have never seen any explanation as detailed as this one.. THANKS A MILLION.

[nase2000]

very good teaching, and actually watching it all happen in the cut-away was very instructive.

thanks a lot for sharing this!

[pancho1238456]

very useful thanks

[oooorigin]

this is really cool. thanks for sharing .

[oisiaa]

We are ALL driving Ferraris with paddle shift dual clutch transmissions over here in Italy.

[adam58x]

Fantastic! Clear explaination but video could be sharper. Go John!

[Haziqevo]

Thank you for this great video. I enjoyed it very much and now I am going to try to make a gearbox using legos.

[oisiaa]

I'm sure K'Nex would be much easier.

[spaskuda]

i wonder if you help me with a problem.

my gearbox is fine going up the gears but changeing down to 3rd and 2nd is possible but but it crunches. also when you are waiting at the lights and engage 1st you can feel the gears spinning a little and hear a clunk as it gos in. Is this a problem with the gearbox or is the clutch not complety releasing? i have changed the oil and it seem a little better. the car is a peugeot boxerer 2.5 tdi 1997. and it has a cable shift. thanks

[newbarker]

I appreciate you putting this up. I need to investigate a problem with my motorbike gearbox and I had no idea how a box worked before looking at this clip. It's quite a bit clearer now!

[831121]

gracias, por este video , neta que me saco de muchas dudas.

thanks for this video, it helpme a lot, thank you very much

[hitchcock1960]

Is there a video on front suspension restoration in the library?

[niccorrado]

very nice video!!!! thanks :)

[bucci777]

Hey John! could you make a video on how to take off and put on "knock off" spindle tires??? thanks.

[Lijimbuka]

Great vid. Thanks! Any chance you could show what happens when one switched to 1st gear while in motion?

[SantoshPolavarapu]

Indeed a very informative vedio. great job folks. appreciate ur efforts to get this up

Santosh

[sthalwille]

Nice video thanks for that.

but you said 20w 50 castrol gtx ??

motor oil in gear box ?

[volumeguy]

The older, chrome bumper B's use 20 weight oil (preferably Castrol 20w50 GTX--it's closest to manufacturer specs) instead of tranny fluid. If you have an overdrive model, like I do, it's best to change it about every 20,000 miles or so, or your O.D. can engange/disengage at will. I use the same oil in my dashpots on the S.U. carbs--never had a problem. Great vid on the gearbox. It's nice to see how the thing works.

[seriously111]

Fantastic videos. Thank you, John Twist!

[bpad]

I agree. These videos are fantastic! Now, I finally understand how a gearbox works! How long can one expect a gearbox to last before replacing?

[bazuk7]

Your wisdom is appreciated. Thank you for taking the time to do these, very informative to an MG 'noob'.
