After watching this, ive been dreading the day of rebuilding my transmission. my local shops dont repair manual's transmission's anymore which is odd to me. Watching this has given me the confidence to go ahead and give it a shot. Going to buy a used transmission and rebuild it, thank you. Love how methodical you are. Keep it up man .

Maybe the manual trans expert quit his job.😂

Would love to see a long format video like this for a B series gearbox, GSR B18C1 trans especially.

[@GIZZMOTORSPORTS]

I don’t recommend to lube the outer edge of the oil seals, if you can push it in that easily with lube there’s a chance that seal is moving once in service.

[@averyalexander2303]

You are much more likely to damage the seal pushing it in completely dry, I always lubed the edge of the seal and the hole it goes into with whatever oil I had nearby and never had one move or leak. They sort of stick in place once they have been in for a while like how coolant hoses get stuck. Besides, the seal is not under pressure or subject to any significant force during operation.

Hey mate,will make aure to watch all the video after work tonight, i got a question you might know the issue I want to change gear ratios on my Accord cl9 with the and use the ones from the civic type r but keep the Accord 6th gear, so i ve heard very often people have the problem after the rebuild that the 6th gear will pop out under engine load... Do you have any clue maybe why?

[@rawrmadmonkey]

I just dropped in a new mfactory lsd in my 06 rsx and im trying to close the trans but I cant get the c clip to close over the bearing. I tried dropping it snd prying it but nothing seems to work. I opened and close the case several time and cant see anything wrong. The input shaft spins freely and it goes into every gear, only problem is the c clip wont go into the bearing. There like 1/8 inch for it to go in. Any help would be great!

You're very eloquent and concise - it's easy to follow, easy to reference, and it's all just so professionally done - your thoroughness and attention to detail are elite, second to none. I would trust you to work on any of my vehicles, and I would work for you any day (I"m almost 50 and not a mechanic lol).

My rebuild is going great thanks to you and a couple other guys on youtube.

[@escodenny2992]

Thank you for this, I'm currently at an auto training school for the opportunities they offer, and watching this video helped me strengthen my knowledge on this a ton. I struggled a lot with transaxles in one of my classes but now I feel more confident in taking on my next project!

[@joeprobably2817]

This is on point!! And I agree, you should do a rundown/walkthrough on the shimming and clearances. I’m in the middle of this exact build including adding an LSD. The shims and/or clearances are the only things I’m uncertain on how to calculate. This video is already a HUGE help having toque specs rolled in.

[@averyalexander2303]

Same, I'm going to be adding an LSD to my 04 RSX-S trans with the TSX 5th gear and 9th gen Civic Si 6th gear and I'm still trying to figure out the clearances before I begin. To be honest, when I had my D17 trans apart back in 2021, I didn't learn that there were different thickness shims until months later. Fortunately it's still quiet and shifting as good as new after 15K hard miles, so I guess I got it close enough LOL

[@WT5R]

DTI gauge + adapter & feeler gauge. Dial gauge for end float Feeler gauge for diff

[@ShakotanRon]

Hey, this was phenomenal, but are you sure the various hardware that you lubricated (counter shaft bolt, and diff bolts) where wet torque specs? Lubrication dramatically effects achieved torque, and you can easily over torque if using a dry torque spec with lubrication. Also, when torturing you should stop after the first click, resist the urge to double, or triple click.

[@seley4866]

Where will I find the instruction paper that you have?

[@miguelplascencia6093]

I rebuilt my transmission because my 4 gear grinds I fixed it but now my first gear pops out of gear only way to go is to keep my hand on the shifter any thoughts of what I did wrong

[@danielstephens4420]

I was working on a k20 5 speed and I replaced the input shaft bearing. Of course the shafts and the forks came apart on me so I watched the video and put them all back together. What do you think I did wrong if I'm locked out of 5th in reverse? I guess I'm going to have to take it all apart and redo it.

[@gearhead3500]

I sealed the transmission an torque all the bolts I noticed the reverse shaft was not aligned I was able to get a long pick from the shift selector hole to recenter the hole for the nut also I find it really annoying having that plastic inside having to lay the casing down with that piece on the hardest part to me was closing the case while having the spring clip open while you smack the casing an tighting down the bolts

[@John-ts1on]

Outstanding video with all the torque specks👌 thank you.

[@awolcustoms]

You missed the most important part the shimming process all the calculations for that is the most important on a trans build and you cannot assemble it with old used shims even the diff gets shimming the min you add new bearings to it as well

[@jonathanjovenal]

Approximately 42 seconds into the video I mentioned that all clearances have been checked. I partially assembled the transmission to measure clearances prior to this video and took everything apart again for a complete and uncut assembly video that people can use for reference.

[@anild8169]

@@jonathanjovenal Excellent video man. If you can do a separate video on the shimming process, that would be da bomb. Keep it up bro.

[@jonathanjovenal]

@@RanmaKei Hi, I clean everything with Purple Power Degreaser concentrate. I use a pressure washer for the casings, and submerge the parts and shafts in Purple Power and agitate them with a nylon bristle brush.

Check your linkage 🤔 there's a set of springs. Maybe they are worn out. My guess.

[@chadwickwicky67]

Thanks for the vid man and thanks for keeping it real as well. So many edit things to make it seem perfect but reality is things doesn’t go perfectly and you show what to basically do and look for 👍👍. One thing that worked for me fabulously is when mating the cases , hit the area where the bearings go with some heat. A few seconds with Map or even propane Little does a long way And normally drops right on with barely much persuasion needed with mallet. Also when checking thrust clearance , works great to drop the bearing out too! 👍👍

Would you happen to know if it's possible to use the dc5-r 4th and 5th gears in the 05-06 rsx-s tranmission? If so would different synchros be required? Great video.

[@jethroraj5553]

Did you ever find out if different synchros are needed?

[@David-nb2bc]

Great video and instructions. How come you cannot compressed the counter shaft gears all at once so you don't have to waste time doing one by one? With all that work and the case is open, should have put in a LSD as it looks like an open diff?

[@jonathanjovenal]

Glad this video was helpful bro! Whenever pressing any components on, you should preferably press them on one by one in case one of the components gets snagged. Technically speaking, yes it is possible to press them in all at once, but to ensure no damage occurs to any of the components, I press them in one by one. The countershaft gears are splined so if you were to try to press them all in at one time, the following gear might not align with the splines on the shaft and can get damaged during pressing. As for the LSD, this transmission was for a customer’s vehicle and he did not select to have an LSD installed, just a simple refresh since the transmission was out for a clutch replacement.

[@rehcvlee6577]

Will it be harder to turn input shaft by hand at higher gear and reverse? 5th and 6th gear specifically? My 1-4 and neutral is super light/easy to turn.

[@averyalexander2303]

How much harder? Naturally it is going to be somewhat harder to turn in 6th than 1st since there's less of a gear reduction, but it shouldn't bind or be hard to turn in any gear.

Is there any other seal that can cause passanger axle to leak. I replaced the axle seal but it’s still leaking out

[@jonathanjovenal]

Only use genuine Honda seals. If you replaced the seal with a genuine Honda part and are 100% sure it was installed correctly, you could possibly have worn differential bearings or worn axle shaft journals internal of the differential that could be causing the axle to wobble excessively and leak.
