BEST FIX for the Civic Type R Gear Grind...

[@TORQToolbox]

*Correction* Add 2.3 quarts of fluid and not just 2 quarts. *Update* These fixes worked great for about 6 months, then the grind started slowly coming back. So I replaced the Rear Motor Mount in Oct 2021 with the Hasport 62A. The grind immediately went away and hasn't returned and it's now April 2023. The Mount is Here: bit.ly/3zFiUna

[@aznbudduhboi]

Not sure if anyone knows, but to also perform the fluid level check, there is another bolt that is 12mm in size. As you fill the 2-3 quarts of fluid there should be the level port that begins to drip out slowly. Doing this ensure that there is optimum amount of transmission fluid and that its not under shorted.

[@free_electron]

I’ve been battling 2nd gear grind in my 2019 for years. I changed the fluid 2x with oem before going amsoil which helped. Just recently this weekend noticed a lot of slack and adjusted my Slave cylinder rod. I haven’t had an issue yet after getting onto it once or twice. I also have a billet rear motor mount. If I have another issue, I will also adjust my pedal. Mine occurred most with a passenger and during the summer, so I’m still looking out for it. So far, it’s much improved.

[@JonHop1]

Get proper mounts, stick with amsoil, and get an upgraded MC.. Ive been power shifting and launching my 500whp Type S without grinds for years.

[@weduhpeople8504]

Lol, I sometimes use gun oil for other things besides guns. I had done every modification to get rid of that 1-2 gear grind. Hybrid Racing drop in short shifter, AC Delco friction modified trans fluid, later Hybrid Racing shifter bushings, PRL braided stainless steel hydraulic clutch line. I also installed a modified cmc I bought from k20z3allmotor which didn’t fix the grind without doing my last mod. The last mod that seemed to fix it was removing the delay valve including adjusting the engagement point. I don’t even want to visually see how the synchros look after all these grinds since the first day of delivery of taking my Type R home from the dealer. Wish I did the delay valve removal first.

[@666shredordie]

I removed the clutch delay valve on my 9th gen Si and it immediately solved the grind issues. Similar process to remove it. I've added it to the list of things I hate about Hondas like the rotor screws that just rust on.

[@proz71ful19]

Man ef those screws. Put a screw driver on it, hit it with a hammer a few good times and it should get loose no prob with a torque driver. Be sure to press real hard or you risk stripping the screw

[@kevstr432]

Thank you for this. I hated googling this problem on my 2018 and not finding anything useful. Will be doing this sometime. Was gonna give up my Type R, but now I think I'm going to keep it because of you. Thanks again!!!

[@raidersperez1278]

the only times I ever got grinds was when I pushed the car hard from a launch. I installed the mid motor mount and they were gone. After I installed a short shifter from hybrid racing I got a grind 3 times on the same day just normal driving. I removed the shifter and didn’t get any but I now feel second gear being a little rough. I was going to change my fluid next oil change but I’ll try the adjuster bolt first like you said. Thank you sir. I hope you start posting soon.

[@MonzaRacer]

GM Synchromesh fluid , I literally poured it in , backed car out and the difference was incredible in first .10 mile driving out from shop.

Hey! I was looking for solutions after countless grinds in my 19 R after putting about 10k miles past 5 months with dealer was just trying to pull “we cant do anything about your grinds” and i think cmc adjustment really helped improving the feel of the car! Car used to be very clunky and almost felt like “stalling” first couple gears which made me over think but it literally gotten rid of all the problems I have (for now). I don’t think I will ever do delay valve delete but this is gold. Thank you so much for such valuable information! Enjoy your car!!

I did the pedal adjust when I first bought my 2019 and I only get grinds when I don't fully depress the pedal. I'm currently at about 20k and things seem to be golden. Thanks for the video and I might do the CDV just to have the immediate clutch engagement.

[@TheGrowOp]

Man that snap ring you mentioned gave me issues on my 8th gen Si. Was doing a slave cylinder and I figured I'd buy an exedy one as I heard they make the OEM clutches for Honda and figured I'd give their slave cylinder a try. While I was in the car pumping the clutch I heard a loud POP and my outside guy yelled at me to stop. Turned out they didnt get that snap ring in from the factory and it shot off into oblivion coating my fender in brake fluid at the same time! Made the drive to my local honda dealer and but the bullet on a new OEM one. Haven't looked back since!

[@AdamsYouTube123]

I remember the frustration of this from my 2008 Civic Si. I ended up getting rid of it after major transmission issues after 160K miles. Seeing that the Type R still has these shifting issues, I wouldn't want that headache all over again. I really like the car but I may end up looking for something else to buy instead.

[@g.dubyou6263]

hey buddy i have been following you for quite a while, i started following you for pew pew videos. i have a 20 FK8 and watching this video because i am having the same problem after a few track days. I am also a professional technician and on the power bleeder when you were bleeding the system., buy some dot 3 or 4 brake fluid and fill the power bleeder with the fluid and you don't have to watch the brake fluid level because it will refill as it drains the fluid. I have also found that when bleeding the brake system on our cars they prefer vacuum instead of pressure due to the ABS block. Great video and i would love to se some videos of you tracking the car! Keep up the great work man!

[@kyleburton8034]

I don’t own a Type R, but I do have a ‘19 Si with similar issues. I bought it with 47k miles and 2nd gear seems to have issues at random times....not usually showing up whether it’s hot or cold or indifferent or anything of the sort. I’ve seen where you can replace the shifter assembly bushings, which I have yet to try. With that though, I had realized my clutch pedal has A LOT of play in it before it actually engages and in watching your video, I’m nearly certain that adjusting the pedal will help a lot more than the bushings. Either way, I appreciate the video! (Hopefully you have more on here of the same sort of content)

[@efboy]

I remember having transmission grind on my FG2 SI. I had the clutch changed, as well as the fluid. Apparently, there was a recall on the trans fluid Honda used on the SI at the time. They recommended using the previous year RSX Type S trans fluid if I remember correctly. Also, those wrenches are flare nut wrenches. I’ve used those for fuel fittings ☺️

[@antoniocruz214]

Adjusting the CMC made such a difference in my car! Aside from the grind, my car always behaved weirdly, letting off the clutch- almost as if it had an anvil for a flywheel haha. Seriously, it was always kind of lurching, when shifting and letting off the clutch. After adjusting the pedal stop and rod, it now behaves like a clutch! It honestly made me question my skills, which was absolutely disheartening after buying the car...

[@beenguyen1838]

My Fk8 (19) didn’t grind but it was crunchy when it’s absolutely cold .. I did synchromesh and cmc adjustment .. mine had a good amount of slack from factory .. I was able to adjust almost a full turn until I got resistance .. I can slam gears with no problems. .

[@JonHop1]

Amsoil for all fluids... Making 500whp on my 6speed Type S... NO gear grinds EVER unless they were my fault in the first place from bad clutch control/shifting.

[@jonthecowboy]

One thing I’ve noticed after also owning an 8th gen si is that most people think they have a solution for gear grinds. I’m not sure if each car is just different or if people get some placebo when the grind ‘goes away.’ I hope it works for you, and I’ll have to try some of this stuff if mine ever grinds.

[@Vosovogalsyncope]

Interesting ACdelco works well on CTR. First thing we do on 1LE is dump the Delco for RP or AMS.

[@PinkFK2R]

I had the same issue in my 2008 8th Gen FN2 Type R, in my case it was a finished master cylinder but obviously that isn't the case in the 10th gen

[@jtworksoncars6341]

I find removing the clutch delay valve helps a lot with the gear grinding. Honda MTF seems to hold up longer than AcDelco Synchromesh Friction Modified. All in all, Amsoil Synchromesh MTF got rid of the gear crunches and did last longer than AcDelco SM FM for me.

[@initialg82]

Thanks for this! I did the clutch adjustment and no longer have 1st gear lockout. Shifts really smooth now 🙏🏼

[@Felix.Garcia]

I have only gotten a grind 2 times in 4100 miles... Both times it was "my fault" , power shifting into 2nd at redline. I am going to switch Redline mt90 fluid when i do first oil change. Also got rear mount going in when i do that... But after seeing this video, I'll go ahead and also adjust that pedal and see. Thanks for the info.

[@tkmwong020480]

Most of the Time the grinding into 2nd gear comes from shifting too early into 2nd before You fully have the foot down all the way on the clutch or lifting the clutch too early. It happened during the early stages when I first drove my Integra Type R DC5. After You practiced enough, it doesn't grind anymore for Me, only once in a long while. Most of the time it is the human error more than the Mechanical error. Honda Type R's including the S2000 have had the Best Manual Shifting Gearboxes in the Market for Front Wheel Drives for a Long Time. You hardly hear about having such grinding problems about these cars in Japan and other Asian markets.

2015-2021 wrx has a similar issue as well. its the combination of cable linkage shifter, soft rear mounts, and clutch delay valve. hate cable shifters lol. the sti however, has no issue, it has solid selector rods going straight into the transmission like a proper longitudinally mounted trans.

I have a 2018 si and for my car, it’s not a grind it’s a crunch or a double clunk. Also first gear locks out a lot or goes in half way and pops out. Reverse seems to be hard to find all of the time and it’s very picky about when it’ll go into gear. Third gear would occasionally grind but I found that to sometimes be my fault. Third gear would also lock out like first. My 27won race rear motor mount eliminated the third gear grind/lockout. My Acuity stage 1 shift kit also helped with the second gear double clunk but it’s still there. Reverse is still hard to find too. The first gear lockout is still there as well. It’ll go half way in to the gear then either stay there or it’ll go a little further but not all the way and then pop out when I start driving. Its only a problem when stopped. It’s a pretty common problem for me and can leave me stopped for up to 15 seconds when the light turns green. My friend has a 2019 type r and his car has the same first gear problem and he has an Acuity short shifter with linkage bushings. First gear would lock out. I’ve even experienced it when testing his short shifter.

Grinding synchros in a LITERALLY brand new transmission is just absolutely awful.. nothing can be worse.
