Type r Tranny issues still?

I changed my oil as soon as it hit 600 miles. That is the break in mileage from Honda. Think I was a little over 600 miles. Engine today don’t really need broke in they do a little for the rings. Engine breaking is what seats the rings in on a motor like 4000rpm in 2nd or 3rd an don’t use the brakes an let the car stop its self. I ran mine up to 5-6k rpm an let it rev itself down in gear after about 4-500 miles. Free reving an full throttle jack rabbit starts as my daddy use to call them that’s what glazes cylinder walls. But again that’s hard to do on modern engine the metals in the motors are better about the only thing on new cars that are better lol. Cross hitch stays in cylinder walls longer on newer built engines except dodge an Chrysler lmao... but yeah I was always told engine braking is how to break in a motor.... & I have never had an issue my old gsr used maybe quarter of a quart every oil change an she had 140-150k on her

Honestly that annoying delay valve in SC should be removed no matter what, my car feels so much better without it, highly recommend it.

Would be nice to get direct comparison. Maybe someone near me will do it and we can compare. I just worry that the Engineers that decided to put it in there must have had a good reason. Less shock to the driveline and stuff...

One more thing to add rev match when turned on isn’t going to break in the syncros. I have finally turned mine off a week or two ago an one of my many theory’s lol I am thinking it’s not breaking the syncros in the transmission in there not working hard at all when u rev match a car so to everyone try turning your rev match off an don’t manually rev match the car let the trans an the clutch work on the car I had one bad shift today an it was tonite a little while ago it was a little rough going into 4th but didn’t lock me out
It just didn’t go in smooth. Like I said I didn’t expect the fluid to fix it. It has made the tranny shift smoother that’s for sure. I agree with one of the guys on here that said the cmc will not fix the lockout issues he is probably 100% right. I am still on the fence if I wanna change it to the one I modified. I am probably going to drive this thing without rev match on an let the clutch an trans do the work for a while I think it is getting better. I would also get a little binding down shift into 2nd when the car was new it was like I could feel the gears not mesh properly that is gone had that issue the first couple hundred miles. Like I said I think rev match is not letting the syncros break in properly

For me it was a big difference in smooth driving, it felt like I could time my clutch release better and feels like the biting point is always at the same spot, you will definitely feel it driving back to back with the delay valve. You can always just get a new Slave Cylinder and remove the CDV, just swap back with the original one if you don't like (doubt it).

Seems like Engineers put it in place for people who release the clutch really fast/drop/sidestep, at high rpm that can lead to a lot of shock, but it seems like CDV also takes away a lot from clutch feel.

I've read a lot about it on different honda forums and generally people who performed this mod really like it, some say that it's not that big of a difference but choose to keep it out anyway.

I have a 2017 R 4xxx, I'm on amsoil tranny fluid and CDV delete, I never had a gear grind and it's been a while since I had a 4th gear lockout, but I don't think delay valve in SC would contribute to 2nd gear grind, unless the plastic valve is damaged from heat or something.

Jack is a very good trans builder. Another thing I have heard on these type r’s is the clutch an flywheel issued thought I read something yesterday on here but I could be wrong he explains what lockout is on a shift. But like I said it would usually do it in more than one single gear it would be doing it in different gears.

I totally again with u. The delay valve only works when the clutch pedal is let up not pushed in so it works when your letting up engaging the clutch to flywheel/engine not when u push it in releasing the clutch from the flywheel/engine.... that’s where the lockout is when we push the clutch in an try an shift from 5th to 4th an delay valve shouldn’t effect that. Which makes me think it’s clutch drag or something is out of spec in the trans

I am gonna bet the clutch drags slightly on these cars an that’s the issue like I said I only get the problem when the trans is up to temp an I have been driving for a while

I sold my last talon to jack and one of his co-workers forever ago haha ! He is indeed a very knowledgable guy ! I wonder if the hydraulics in this car are not up to the job for the fast shifting transmission ? Maybe it needs a more direct linkage from the master to the slave ? A braided stainless line perhaps ? I dunno i'm not a engineer but it seems like it may not be a internal trans issue as you are stating. Wonder what realtime racing has done (if anything) with the trans setup on the race cars?

No idea buddy... it’s weird why it only does it going into one gear like I said mine feels like it’s getting better which is also weird it’s like the car was good for 3-400 miles then started acted up then changed the fluid at 1300 miles an was good for 2 days an it’s not locking me out it’s just not smooth going into 4th from 5th after I have been driving the car a while an it’s only a couple down shifts from 5th-4th an it goes back to being buttery smooth. Trans in this car has kind of its own lol... no idea probably this weekend just going to replace modified cmc an if that don’t do the job drive it for a while like that it’s not like all the time it’s going to happen it’s just I notice it after I have been driving the car for a good hour or so. Never acts up when it’s cold or within the first hour of driving it... always after I have been driving a while

with it only acting up when warm is what really has me thinking it's hydraulic related either in the slave or master or the line, something in that area. That or like you were saying the clutch / pressure plate is not releasing fast enough, dragging. Dunno ?

idk I am at a loss bro. I’ll probably do the sc then that’s it an just drive til I get tired of it lol

Are you having the grinding issues again now??

No grind 1st-2nd but 5th-4th is notchy just not smooth like every other gear

I am not going to do this but I bet a quarter of a quart of auto trans fluid would make it feel really good has better friction modifiers in it for the syncros. Some of the older manual tranny’s used auto fluid. Not fill the tranny with all auto fluid just a little bit
