EP3 / RSX / TSX / Accord | K24 / K20 Synchrotech Carbon Synchro Install 

I just bought an ep3 that grinds real hard into 3rd unless you double clutch it, or first unless youre at a dead stop and have had the clutch depressed for about 2 seconds. Going to be tackling this exact same project, most likely installing the exact same parts as well, and im honestly mad impressed with this video, i was concerned about trying to find a how to with this but honestly i almost feel like i could do it without even referencing the video after this. Fantastic job

might just be the best install video on youtube.

Hey man, thank you so much for making this video. This video will enable me to rebuild my transmission without any mechanical background, much love

Thanks for putting in the effort to make this. I'm currently replacing the synchros with synchrotech in my 6 speed /lsd in my 3.5 J swapped Acura EL 😎

You just saved me from spending thounsands for a new trans. Thankyou!! Mine went out yesterday.

Amazing step by step video and f the press everyone doesn't have one and even me who has one barely use it ever so makes for a much more realistic step by step ty

This is good. Great video. Better than others I've seen so far.

Excellent Video! I was Able to Rebuild my 1992 Honda Accord 5Spd Manual Transmission, by Following your Video!🤝

Video is great, made me realise I am going to pay a Honda specialist garage to do this for me

I have a crunchy second gear & loud bearings that need to be replaced on my EP3. This video is great. I will definitely be referencing this video when I pull apart my transmission. Thank you !

Thanks for the video! Got a second transmission I'm going to rebuild with this video and swap them out and rebuild the other one as a backup. :)

Thank you bro video is great lol you got into every detail and that’s what I like keep it up.

This video made me want to become a mechanic thanks school starts in April I’ll post again in a few months and see what happened

many thanks for the explanation on what to look for in the wear of the 2nd gear. I am just about to open up an RSX X2M5 trans right now.

This is the best video I’ve ever seen for a transmission rebuilt, but bro, why didn’t you torque nothing down the only thing

I need to rebuild my transmission for my 2013 accord EXL, second and 3rd gear grinds bad during cold start. Have to warm up the car for better experience with shifting. still grinds but like 13% of the time while warmed up. I cant seem to find the model or the transmission but would like to get this thing rebuilt. I was told by a tuner shop that they do ATF for 100 miles to lube the syncros then change back to manual fluid. I need to do the same for my truck.

Awesome video, about to change mine. Getting a second gear grind

@10:10... right as you're making the point about keeping everything in order, but upside down... one of the collars underneath the gear you have in your hand actually flips upside down without you noticing it (I think). I hope it either didn't matter, or you noticed on the re-assemble.

Great video!!! I have the transmission that comes out of the k20z3 added this video to my collection.. right now I have to take mine apart I think the gear case seal broke away , or possibly the input shaft seal the one you have to basically tear down the entire transmission to replace one seal.

2002 ep3 transmission was operating great. Replaced the input shaft bearing. Now Im locked out of 5th and reverse. The only issue I had was the 5th gear sleave slipped off past the top of the syncro. Does it only go on one way? I slipped it back on . Maybe I screwed up the reverse idler? Not sure what I did. Please help. See pic below.

Gonna use this vid to guide me with my trans. Never done anything with a transmission but I think I got it

Hey when I assemble my gears together and have everything ready to slap on the outer case when I put the transmission into gear it won’t spin but if I were to put it to 5-6 it’ll spinn

Hi, I have 07 Accord with 5 speed manual ( K24). Every gear is a battle to shit from 1st, 2nd...and reverse. The clutch is 6 month old and I just replaced the slave cylinder. But same problem HARD TO SHIFT FROM GEAR TO GEAR. HELP..HELP😢😢😢

fantastic video, thanks.

Hello, i was wondering if the synchro has to go in a certain spot or are they all the same? It wasnt specified in the video, but just wanted to make sure before I do this to mine. In the video you said the 2 big ones go onto the couter shaft. Could the other 3 just be put anywhere since theyre the same?

Did you purposely leave off the synchro springs? I imagine it will still operate without them but won’t have that definite “click” into gear etc. nice indepth vid , thank you for this 👍

I appreciate this video!🙏🏽 Subscribed!

Would this apply to a 2006 civic si with the k20z3

For future reference i believe you have the spring washer that goes on mainshaft wrong

Has anyone done this on the 2g eclipse transmission

very useful video man, i will definitely keep this in one my favorite for future reference!!!!

Great video! Definitely going to subscribe. Keep up the great work.

hey in need 1st 2 and 3rd gear synchro for my 2014 accord 2.4l 6 speed transmission its making funny sounds grinding plus it pops out of gear in traffic like wtf please help me

Hey. I'm rebuilding mine k20z3 transmission. And got everything mock up on bench. My 1-4 gears and neutral is easy to spin. But my 5th, 6th and reverse is a bit harder to turn by hand. Is that normal or what am I'm to look for?

S2000, gonna replace 2nd gear synchro, others if need be. Where you located lol I'd love your help

Is the 2003 civic SI stick shift transmission any good for K24 or should I get another one?

Very helpful video tanks . Hey do u think a k24 transmission fit on k20 block Goin to ep3 civic chassis

🔥🔥🔥💯

i need a six speed transmission , 4k rpm in 5th gear at 80 mph is ridiculous smh drives me nuts 😂

Great disassembly and reassembly video. 21:19 Why not use the portable pull-press to press the gears back into position on the counter shaft?

So basically the same process for j30a4 6 speed?

Will a EP3/RSX-S Synchro set fit on stock K24 Gears and can stock K24 synchro set fit on EP3/RSX-S gears?

Hi. Can i put the guts of a 6speed lsd ( k20z3) inside the ep3 trans case? So i can keep the ep3 VSS and not have to rewire for CSS. Thanks in advance.

Great video

Thank you for this video. 👍🏻👍🏻👍🏻

Can you tell me if I can use a 07 element 5spd trans for a k swap in a eg?

Great video, thank you.

You dont put sychro spring

Is this the same for an 03 crv 5 speed as well?

A brass drift is good to use when you’re tapping that on @ 22:20

Do you get any kind of deal or referral code through Synchrotech? Currently about to have my APG6 Honda trans rebuilt

I have 2007 Honda Accord six speed gearbox but it’s not letting me shift into first gear or fifth gear with the car off or on any ideas what can be my problem ?

How’s the reliability on the synchrotech synchros? I know oem honda is usually the way to go because if reliability but the synchrotech ones are just the first that pop up for sale on many websites they seem readily available. Just wondering should have any issues using them rather than oem?

Hey bud great video ! I need a new 2nd gear for my ep3 trans

This is awesome. Thank you

What synchro set do I need for a CRV trans? Doing an AWD build and looking to refresh things. Also switching to a 4.38 FD so need the 40mm counter shaft bearing.

What’s the exact name / link for the puller on your vise at 15:15 ?

Hey Boss! Do you still got the plug on an oem 2nd gear for an ep3 trans

hi i have a euro r 6 speed transmisión (tsx) can i use a rsx shifter by only replacing the selector? thanks in advance

so you did not put any snap rings on any of the syncros and that little piece that you did not know what it was is a bushing those tabs had to sit down intro second gear do yourself a huge favor and get a complete service manual or have someone else do your work for you

Hey man I’ve been having an issue on my rsx type s 6 speed tranny.. basically goes into gears but not 6th and it won’t move on any gear it only moves in nuetral which I don’t get, if I let off the clutch on nuetral it wants to stall. I’ve changed the clutch(full kit) tob and pilot. And this issue is still there.

Awesome video. I currently have my 6 speed apart and I’m changing the bearings and seals whilst installing an mfactory lsd. I don’t suppose we could have a chat about the shimming of the gearbox?

That's a good video got one here doesn't work how can I check it

Would you recommend replacing synchro sleeves and besrings while in there ??

I have a question, how to identify whether its a tsx or rsx transmission?

I need the hookup for a 2nd gear on the counter shaft for an 8th gen 6 speed

Hi! Which transmisión fluid do you use for this gearbox with this synchros?

Is there a difference from the rsx gear stack and the accord gear stack?

YOUR THE MAN!!!

Thanks for the info..

Do you know the torque specs for the bellhousing bolts to the block?

Hi, hope you can help. I have an accord type s (UK, K24a3). I purchased and had installed a same gearbox but with ep3 gears 1-5 with ep3 4.7 final drive. My speedo is WAY out, over 12% at least. What gear does the speed sensor use to work the speed out?

I’m guessing the 6 speed is different? I didn’t see anyone else use a puller

Дякуємо!

Do you know if the synchros will be the same for the K awd transmission?

So I'm going to try this in my rsx type s 6 speed. Is the extra gear pretty straight forward?

Are Synchro Tech Brass Synchros good for daily driving ? I’m also gonna need 2nd gear 1-2 sleeve , 1-4 synchros, 3-4 hub and sleeve, shift arm would everything synchro tech would be good ? Or should I get some stuff oem

Quick question, did you check for clearances on forks, mainshaft thrust, and diff thrust when you did this assembly? Not sure how important it is tho hopefully you can help me out

You misplaced the mainshaft washers, the cone goes towards the bearing, then upper to the mainshaft the flat one.

Guys hopefully you can help me out , I did swap on my ep3 2003 k24a2 motor and transmission type s 2003 everything works except reverse won't get gear , it does if I do directly from selector other than that works likenit should be . There's anybody that can tell me what could be , please . Thanks a lot 🙏🏼

Where did you end up buying the 2nd gear from that was cheaper

What's that tool you're using to press the shaft?

Great video!

Great how to man!

Are all the synchros the same or does it matter where they go ?

this doesn't look that bad except for not having a press or a puller.

Looking to buy Carbon Synchros. Have a link to purchase?

Where do you recommend getting the Ep3 gears ?

I really appreciate your videos but please get rid of that painted work bench. It makes it tough to see those parts especially on a cellphone screen. Thanks

Great vid! Where are you located?

Thanks a lot bud

Thanks!

Is this a manual transmission?

I’m redoing my synchros. How much of a discount can you offer? I got a 4th gear grkind…

10:42 Lmao, don't get in trouble with your mommy or your wife

Hey there, if you still can get one, i need a second gear for a 04 tsx

Hi

Wonder if he realized he forgot the snap ring on the synchro

I need a second gear

Do you still have those 2nd gear? Email contact?
