I just purchased a R34 GTR and drove it 2000 miles back home (once in a life time opportunity - best drive of my life) but around 500 miles in something happened with the clutch where the car would not go into first or reverse when stopped. So I currently have to start the car in 1st or reverse and then "release" the clutch like normal and the shift like normal once I am moving. And If I try to put the car in first or reverse when stopped I can feel some vibration on the shifter like something is still connected between he engine and the transmission. Nothing is wet around the master or slave cylinder and I seem to get full travel from the slave cylinder - I am thinking the hydraulics are good since I can have the car in first gear with the clutch depressed and engine running and not stall out. And when the engine is off everything shifts as it should.

Firstly, great to hear you are enjoying the new car!

I'm not a gearbox expert but I agree the hydraulics look OK. As you have a pull clutch it is possible the release bearing or fork are disconnected from the pressure plate, but you should be able to see/correct that through the gap in the bellhousing. If that is the problem you should be able to reconnect it through the bellhousing gap as you would when putting the gearbox back in. This is the easier problem but less likely as you would also have issues changing gears on the move unless you are rev matching (and you didn't mention you were).

Is the issue definitely only 1st and reverse? can you choose second while stationary with engine running and clutch pedal down? That would imply it is some sort of selector/linkage issue which is going to need gearbox off to fix

Disclaimer: totally different car

My Honda's shifts were a "little" notchy at high RPM and the clutches engaged pretty high, no amount of bleeding fixed it, I thought it might have been the syncros, turns out the old girls clutch, pressure plate, fork and thrust bearing were worn, after replacing those OEM parts with new OEM parts the clutch engagement was much lower, was lighter, and shifted at high RPM like butter

I'm not saying this is your issue, but there are alot of moving parts that are considered consumable items hidden in there

Well no one would have guessed - including me. I removed the clutch to find that one side of the clutch completely ripped off the plate. So I drove about 1500 miles with one side of a clutch lol. I guess the ripped off clutch material was still kind of connected causing the transmission to not stop completely thus making first gear hard to get in.

 

p.s. don't replace your clutch on the floor of your garage unless you have a great therapist

yeah aint that the truth!

I would still double check all of the heights and fork operation, and replace the throw out bearing while it is all apart.....depending how long the car sat without use it might be an age problem (if that is even a thing with clutches!) but it could also have been slipping a little for a long time

Me and me friend did this on his 33R in his basement carpark only using the torch from our phones. That top starter bolt musta taken us about an hour alone. Needless to say I am now an expert in removing R boxes in a basement carpark with iphone torch and limited number of tools :D

    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
    • Well the articals keep saying a Q50s (Skyline in Japan) with a new Manual gearbox. I like the talk about the new looks with the round tail lights. I hope they bring back the retro look like they did with the Z
