2019 nismo wont go into gear
 

hey guys
just got back from butttonwillow, came to take it off of the trailer and saw it wasnt getting into gear. it will go into gear when the car is off, but not when the motor is on. i didnt try putting it in gear and then turning the car on, cause whats the point i figured ill just take it straight to the shop. clutch reservoir is full and clutch pedal is not sticking to the floor. super weird car ran super smooth all day except for i looped it on phil hill and the car kept cutting power at 4k so i restarted the battery and I was good to. I think i fuel starved it, but the transmission was shifting and running super smooth since then. Oh and stock clutch stock everything on the trans only have a coolerworx short shifter and rjm pedal

did i blow through the csc?

let me know gentlemen

thank you

Seems like the clutch isn't disengaging. Transmission is spinning when the engine is on so you can't shift till the engine is off. Why that's happening could be a lot of things.

joe @ zspeed is saying it could the cmc, either way its at the shop right now being opened up

going to go with a nice quick shift set up from z speed

Sounds like you overheated the stock clutch and it stuck itself to the flywheel and pressure plate. You will know when it is taken apart and if you see any hot spots.

CMC is my guess, too

could be, dropping the trans right now and ordering the new parts tomorrow

should i get a new pressure plate as well?

Also, should i be getting anything else to beef up while the trans is out?

lol could be, but might as well switch out everything while its down

The CMC would have been a good place to start because you only have to remove the clutch pedal to replace it. If you already have the transmission out, then its too late for that. When replacing the clutch/CSC always make sure to replace the CMC also.

Pilot bearing failure will have your exact symptoms.

ordered a complete quick shift kit from zspeed, oem cmc, arp pressure plate bolts, zspeed flywheel bolts. do i need anything else? any help would be appreciated

quick shift kit felt great. all parts had some heat spots but nothing terrible. if you pumped the clutch enough it would go into gear. so im guessing either csc failed or cmc

Did you use Motul RBF 600 or Castrol SRF dot 4?

Just regular dot 4, boiling temp is 536

I use my Castro racing srf. There is improved feel over the others.

That would be why. Use one of the two I listed above.

That reminds me. I got to get more. Just wish it would come down in price. :shakes head:

I here ya! I have two bottles sitting on the self. Glad I bought the when I did. The other great thing about it is you don't need to change it more than once a year. I know some guys that track that said they change it every two or three years.

Thanks for the heads up

Should I flush it now or save the 150$ and do it after a year or so

If you are not experiencing any issues and your fluid looks clean you are probably good to go. Castro Racing SRF is always in demand so that is your first clue to its performance. If you can get it and have it on the shelf for insurance as it goes in and out of stock for months at a time and that is why I bought two bottles a while back. I just happen to be at a shop that was about the only shop in the nation to have it in stock and I was there when the UPS guy delivered it. That shipment was gone in two days.

castrol is 518, wouldnt it 536 be better?

I'm guessing you're comparing apples to oranges. Because Castrol SRF is top shelf. That DOT 4 fluid (ATE?) is probably 536F dry boiling point and likely around 375F wet boiling point. SRF is 590F dry and 518F wet. Big difference...

gotcha, i guess ill flush and replace

shop is assuring me they run them on all of their racecars and have no problem changing it for me. but they're like stop tripping your'e fine we run it all day

LOL, it may work fine until it doesn't. Regardless if it is overkill then so be it. My motor is over build everything and if it is good enough for the highest levels of road racing and I can get it and use it...I am all in.

Hit up Mike Upton on FB he sells a vinyl clear hose for the Clutch MC- reservoir that wont disintegrate and cause premature wear on your MC.
Oil quality is one of the main factors in MC life. Another thing after a good run is a pinky oil temp check of your reservoirs to determine if you need to switch to a better fluid.

I kind of hate switching multiple parts all at once since it'll be difficult to pinpoint the actual fault but for the sake of "while we're in there" I understand.

ill def look into that hose! thank you

called joe at z speed he said even dot 3 fluid works and any dot 4 is more than enough
