full d16 transmission rebuild 

Followed step by step. No problems and shifts perfect. No noise no grinding.

Duuude, that concrete trick for output shaft disassembly is a life saver! So simple it's almost genius. Thanks a lot bud!

I made an youtube account just to thank you for this video, awesome thank you. H+

Great video... now I'm building confidence to rebuild my transmission!

Awesome job! Thanks for taking the time to share and do this video! One thing that I want to add, just in case someone ask, is that on the B18C1 and B18C5 engine the 3rd/4th hub of the mainshaft is install the opposite to the D16 engine with the "U"-shape-teeth upside down.

I did a k series only now jumping into the d series, thanks for making this very informative videos, your right many make videos but skip out some of the important things that needs to be addressed. Keep it up 👍

Now I understand what happened to my transmission you were a great teacher💪👌 thank you.

Thanks for the detailed video! It saved me a ton of time rebuilding my SLW.

just rebuilt the trans in my 89 sedan with this video, saved my a$$ on quite a few things, thank you!

I don't need to do this job right now, but it was very interesting. Thank you for showing all the steps and talking us through it. Well done, excellent video! Thanks for sharing!

I'm about to do a rebuild on my Y5 and need to do this too. Glad I found this, it'll help a lot. Thanks man!

Thank you for this! Rebuilding my 93 and having something to follow along with is awesome.

best video on how to rebuild the dseries transmission thanks for the upload

Great video. Thank you for taking the time to put this out.

Cheers pal, about to strip down my '98 aerodeck 1.8. I imagine its a pretty similar setup

Input Shaft Bearing is still available in Japan.

Awesome video, helped me recon my S40 with a kit from Ebay. There is advice in here I couldn't find in the manual, and the pics helped me get all the parts in the correct orientation, and position. Thank you very much Cervan!

Thankyou so much for making this video for everybody. i recently had an issue with my 1996 civic. I heard a horrible grinding coming from the transmission area. It just started doing this out of the blue one morning. My first thought was that it's an alternator/AC/idler pulley. Then I noticed that while shifting, the clutch would engage when my foot had only lifted up a half inch or less from the floor. The grinding sound was present whether I was pressing on the clutch pedal or not...it was just always grinding. By the time I left work that day, there was no pedal resistance and I was unable to shift in to gears while the car was running. Although the pedal did return back if I took my foot off it. I had to get towed. Anyway, I decided that maybe it's the clutch and that I would replace the clutch, and throwout bearing and that should solve the issues. But now, after having the tranny off, I noticed that the input shaft seems to "click" when I turn it back and forth by hand. i cannot tell if this is because loose ball bearing rolling around from a broken bearing or something else. I was going to take it apart. The car has 205k miles on it. Any advice? Apologies for the long winded post and thankyou.

Paterico (preludepatrick) from DSO. Your snap ring technique helped me separate my transmission case tonight. Thanks!

1996-2000 tranny is basically the same, except there are 3 little spring loaded detent balls on the shift fork rails. Didn't know they were there till I took my 97 apart. The retaining bolts are accesible from the outside. Shift forks looked a tad different but function the same way. Thanks for the informative video! I thought I had similar problems to the one in the video since I was getting pretty severe gear whine in the lower gears and a noticeable growl at higher speeds. Turns out the counter shaft bearing was walking out of the housing like you described. Tapped it back in and punched the housing like shown. Fortunately all the bearings are still flawless. I'm assuming the bearing walking out was causing the lash in the gear sets to be taken up and causing the whine. The growl I'm assuming was from the counter shaft riding closer to the ring gear and removing the lash there.

you're a legend dude, I'm about to rebuild mine and i was pretty scared to do it 😅

Gary---- first, I must say THANK YOU for taking the time to explain this rebuild in such detail for us to use. I am quite experience and handy with cars, etc... but have never rebuilt a transmission. You made it easy... EXCEPT! :( I have no 4th gear now and was wondering if you could help. I replaced the following parts: all bearings, seals, synchro springs and synchros, slider sleeves, a used replacement set of shift forks, and fluid. Now, after the rebuild, 4th gear pops out and will only engage IF I force the shifter back with hard force but it wants to keep popping back into neutral. When I reassembled it as per you video, I did notice that when I installed the interlock guide bolt in the bell housing, that the shifting became tough when I bench-tested it by hand (shifting). I will admit, that when I first installed the interlock bolt, it went it with ALOT of resistance... Now, after reinstalling it and making sure there's clearance, it threads in smoothly, but still have the 4th gear issue. (pops out aggressively). Any tips, or help is GREATLY APPRECIATED.... Thank you again for the video! You're a great mechanic and TEACHER.

the sacred video. extremely helpful with my build

Dude thank you for the video. First time rebuilding a trans myself wanted to learn and this helped a lot!!

Great video, thank so much for making and posting it. I am working on a 1998 civic ex 5 speed box. There is one thing you may want to mention! There are 3 detente screws that must be remove before you split the case. Otherwise three steel balls will come shooting out of the case. Also I would advise you to use a brass hammer when beating on the gears.

Can you do a full Itr/gsr rebuild please im trying to save myself a 500 labour fee :(

Dude in DC shirt: *stares directly into camera and hits douche flute* Me: *jizz in my pants*. That was a power move🤣🤣🤣

Thankyou for sharing the knowledge to everyone and for giving me the courage to rebuild my tranny instead of spending almost 1k to someone else, also i love how you messed up so many times but still left the mistakes in the video, respect! XD

don't pound the shaft so hard, esp on a metal table, you risk deforming the end. just get a puller or make one to pull it off

I messed up a little with the guide hex bolt that goes in the bell housing , I put it in was a little tight took back out and it left a small dimple of the right guide I got it in there how it should be but a little harder to turn gear selector left and right now

Alrighty well I have a new issue , I replaced the mainshaft bearing the small one and the large one . I put case back on and was real hard to get on and now it's binding and I cannot rotate the mainshaft by hand . The large bearing on the top of the mainshaft is new and super tight going into the case also the bearings on the diff we're tight too . It's being a bitch to do . Also not sure my lock ring snapped in but I think it did . Also had a little issue with the hex bolt in bell housing that locks the part in place . Gonna take case back off and redo it all. I did not take apart the main or counter shafts at all just the two bearings replaced .

Awesome video, I just did a manual swap, found out afterwards that I couldn’t shift into reverse. Couple questions for you since I am going to attempt to rebuild, it is a 98 civic that I’m working on, trans is from a 00 civic. Could it be the fork? Or possibly the ball bearing shifted? The reverse portion looks fairly simple. Does it not have a synchro? Any recommended rebuild kits you go with?

so tell me why a shop charges a grand for this when it took this dude a little over an hour........

Where can I buy the friction dampeners for a 91 transmission or are all them the same

I've been trying to get my case to fully close for an hour. Everything looks identical to yours, I've triple checked everything. It took so long I had to remove my Honda bond because it dried lmao

Rebuilding a transaxle on a table with a bench grinder on it. You can hear the grit every time you set the parts down on it.

Wacth your video, to rebuild my trans, everything is working great, thanks a lot , merry Christmas

Hi, I followed your instructions. But after I did the light tap upside down when finished. The gear actuator is now stuck. Can you help?

Great video. Very impressed

i need my 00 civic ISB DONE, WISH U LIVED IN OREGON

now i just need to take my transmission out to see what’s going on with 4th grinding when i do a over 5k rpm shift hopefully not the shift forks

all good except for the guide bolt. I could have sworn it had clearance and tightened it down. Checked the gears and could slide back and forth but not over for the rest of the set. I pulled it back out and sure enough I just knicked the side of the slot. Shifts great without the guide bolt in but as soon as its back in its tight all over again. May have bent something. Hope not as not sure where I will get a replacement. Just did all new bearings and seals too.

Legendary. Great first video. Many thanks.

Concave washer is called "belleville washer".

Awesome video taught me alot

GREAT JOB YOUNG MAN!!! SAW YOUR FRIEND SQUANKING...LOL...I HAVE USED GASKACINCH ON ALL FLAT MSTING SURFACES...NEVER LEAKED...EVER...ALL BIKES...CARS...VW BUG CASES...Just saying way cheaper than RTV...NO SMOOSHING EITHER...

Hey mate just to let you know if you use a screwdriver in the pry point and then shove your bar in between the halves, where the silicon is then you can get much more levering and its much easier to control splitting the 2 parts.

19:00 You should have gotten out a needle file and softened up those splines a bit, instead of hammering the snot out of it. Espeically since we all know those thing just fell out when you impaled the assembly onto the concrete floor.

Thanks guys, if you have any questions feel free to ask. I'm a novice when it comes to videos so forgive my horrible recording skills. I'll try and do more videos like this on b and f/h series transmissions as they come in.

Great info thanks for the help

I dont know why but I broke two of the bearings with clip retainer on them. 😞 Maybe the retaining clip is damaged or bent

Very interesting to see a manual inside, i rebuild autos for a living and this seems very similar to a DSG on the inside...

Thanks for making this video very detailed. I am going to rebuild my B000 D16y8 Transmission here very soon and I am going to use this as a guide! cheers

You are a legend

I’m going to have to do this on my d16 out of my 3rd gen prelude. If I find gears or shafts need replacing? Is there a source for that or will I need to find another used trans and hope they are still good?

So I just rebuilt my trans on my 89 crx si. It’s a cable trans and everything looks good I’m able to bench shift it but then when I put it in the car it’s like it’s stuck in gear. In neutral it will start to pull off when I release the clutch. And it’s very hard to get it into in gear position. Any help would be great. I didn’t lose any shims and from why I tmemeber mine doesn’t have any detent balls that would’ve shot out anywhere. It’s a 89 si cable trans on a d16a6

I have an issue... Kind of an SOS. Ive rebuilt a couple of these with good luck so far, but I'm stuck on one. At exactly 16:42 when you say "slide it down" you are sliding down the 1-2 shift shaft sleeve to engage 1st gear. I have a brand new synchrotech shift shaft sleeve and carbon synchro set. All gears work fine, but the 1-2 shift sleeve on the countershaft absolutely will not engage either 1st or 2nd. I tried the old one, same thing. Even tried a couple old synchros. Friction dampers lined up, all gears and synchros facing correct direction, synchro "rings" are on... Everything appears correct as always but now all of the sudden regaurdless of the combination of old vs. New parts I cannot get this thing to shift into either 1st or 2nd. For the record, I even assmebled the trans out of hope that with it put together and with some leverage it would be able to shift, but no 1 or 2 still. :/ any advise id be more than gratefull.

Awesome video Where can I buy the parts to rebuild?

My second gear pop no grinding I check the gear snd syncros seem to be good what can also cause that issue

Good video dude.

Hello there. Good video. i have a 2004 Civic coup and 2nd gear grinds everytime i put it in 2nd. is probably the syncro that is worn right? thanks !

Now what if my transmission is grinding on 3rd (just started) and 5 (already been). I get occasional grinding. Should I rebuild or replace it?

Thank you must detailed video hope you make more videos like this 👍🏼👍🏼👍🏼

Can you please do one for a 2000 Honda accord transmission

thanks a lot dude, great video man!!

Great information.👍

My input bearing has words stamped on the opposite side. My plastic bearing holder base is on the side with no words. I assume I ignore the words bit and install it with the bearing holder facing upwards.

Your a life saver!! Thank you!

Put trans back together and the shaft if a little harder to spin by hand

oh man the grit on that table is now all over the gears and machine surfaces. and put some gloves on man!!!

When you put the counter shaft back together you said make make sure the tangs are lined up before you pound the gears the rest of the way on and there should be no up or down play. When I put mine back together I did it exactly as you said but for some reason there is a little up and down movement no matter how hard I pounded it on. Do the splines have any specific spot they go together?

Thanks for the great video man

the main reason i'm watching this video now, while we have typical rainy day in UK summer i can get my gearboxes apart. I've been converting my HRV for fuel econemy, last summer i fit d15z8 civic engine in HRV with lean burn but 2nd stage is swap 5th gear from civic gearbox to HRV gearbox as lean burn doesnt work over 2500 rpm in 5th, civic vtec-e has longer gears so time to take both apart now and see if d series HRV box shafts are same size, ive seen a few others wanting to swap 5th for longer one to reduce rpm on highways, will let you know how we get on:0) thanks man

Is this channel still active? I certainly hope so. There's probably so much I could ask you about.

Thanks for the video! Whats the trick to getting those diff bearings off?

I was really interested in the disassembly but questioned why he didn't clean any grit off the parts ,then when he pulled the ball peen hammer to HELP assemble the gears i lost it.he definitely has done a lot of those tranneys ,but really don't ever use a hammer to reassemble,that means there's a bur or grit in the splines.Mr Honda is rolling in his grave,and cursing the American mechanic.haha

how come gears weren't replaced?

Additionally. I don’t see why the guide bolt is last. Why can’t it be done right before the housing is put on? This way you can tell if it’s aligned properly. Why not?

Awesome vid! I wish I found this before I changed my Input Shaft Bearing!! I went to the civic forums and went by pics which were not as complete as your tutorial! Question for you: I knew the order of the washers on the input shaft bearing but did not realize (till I saw it in your video) that there is a specific side facing up. What would happen if the spring washer was put in upside down? Will it cause slow uneven wear? or some type of catastrophic failure while I'm driving? I just finished installing the tranny back in the car in -21c winter. I don't want to have to take it out again just to check...ha ha! Again, great video!

u are awesome for this video man thanks alot

Can you help me my 97 manual trans I can't get the main and counter shafts out I removed that bolt but they won't come out

Cervan can you please do a video on the automatic transmission for a 1993 Honda Civic ex coupe. I want to know how to rebuild it myself. Thanks.

Great video, by the way may I ask for an advice. i have a honda civic with a stock B16a transmission (manual) when Im in low gear (1st to 3rd gear) I hear a humming sound.. but when I go to 4th and 5th everything is smooth (no sound) by the way shifting to any gears are smooth. It could be the input shaft bearing? Thanks

do you have a source for parts? honda has discontinued most parts and they are on constant backorder with rockauto. i need synchros

my 2nd gear keeps popping out. my counter shaft bearing walked out of the case, think that is the problem? doesn't grind or anything just pops out.

After changing all the shift soleniods and neutral saftey switch would those bearings be next? Car is acting like its in neatural after driving around no CEL

How do you take out that bearing that u stated potentially walks out that you hammered in??

What was the rebuild kit part number?

Awesome vid man, anything special when switching to a LSD? Or does it just install the same as the OEM diff?

I can’t turn the input shaft after tightening transmission housing bolts. Snap ring engaged, it’s fine. But when I tighten the bolts it won’t budge. Please help!!!

what happens if you put it back together and shaft won't spin?

Thanks for the video. Would you happen to have a 1/2 shift fork for a P20-B000?

If step#1 fails due to a stuck guide bolt is that a show stopper? I don’t see that it is. Is it mandatory?

Hello may I ask what kind of 10w30 brand do you prefer to put in ? :) and do you put more or less doe to viscosity or you do the right amount 1.7litres ? :) thank you

Hey I had 3 little balls come flying out when I took out my case apart and I can’t figure out where they came from any ideas 💡

Very cool video, thanks

thank you very good.

Thanks, good video. I just split the cases on an '89 D series transmission to check the synchros before install. They look great. BUT, question with the inner input shaft/mainshaft bearing.....the one that occasionally gets stuck in the case when pulling cases apart. Mine spins great, no noise....but how much "axial play" should that large bearing have? I suspect it gets taken up once the main shaft is installed and cases go together but can't tell whats too much? thanks!

Any one know where i could buy the friction damper?

Need some help PLEASE! About to toss this one accross the garage and buy a new one on-line. I just put all new seals and bearings from Honda in my transmission cases....did not touch the gear assemblies at all, just put them aside and dropped them back in. Now it won't go in reverse and 5th is tough too. From what I can tell is that the 5 gear selector ring appears stuck and is very stiff??...I cannot slide it back and forth by hand (need a screw driver). I bought this thing used and never ran but the guy insists it worked well....syncros look nearly prefect. I am really stuck on what is going on. here is a video of what appears to be hung up....not sure why its affecting reverese and 5 but it is. When its back together I shift with hand and it slides over okay, maybe a little stiffer on the Reverse and 5th side of the assembly but they just dont't shift in to gear....5th will go but very hard to put in by hand. Reverese would need to t be hammered in and I dont't wanna do that!! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-S7BmsGDvzHw.html
