Clutch Issue?!?

Symptoms:

1. Fang in 2nd, goes to 4.5-5k rpm then sortof sits there while the speedo goes from 40 to 70 or whatever.

2. Similar in 3rd

3. Engine RPM *sounds* the same, so I don't think it is the RPM gauge with a problem, and the speedo is going up sortof the way it should..

I haven't done any mods, the weather hasn't been any different really. What *has* changed, although the problem started before, is clutch fluid being topped up (leak from master) and HICAS reset (was full of fluid but they forgot to reset, so light stayed on).

Anyone have any ideas? It doesn't seem to 'slip' in 1st though its too fast to tell really. The mechanic I took for a drive and he drove doesn't think it is the clutch, although it didn't happen as badly.

The only thing they suggested was maybe the pressureplate springs were a bit old so maybe in some situations it isn't clamping...?

On the plus side, means I don't have to fork out $1200 for a new one just yet <_<

Sounds the opposite to clutch slip, usually clutch slip the revs would shoot up but your speed would remain the same

But yeah put it in 5th at low revs, and hold your foot flat till it starts building boost. Sounds like youve done something similar in 4th anyway. Just saying its a bit weird that the speed shot up but revs remained the same

OK that's it, it must be slipping. Now in 4th if I give it everything it definitely slips.

Does anyone know if it could just be the pressure plate springs, and how much that would cost if it was?

You need to replace the whole clutch not just part of it

I can get npc clutches cheap. Pm me if keen

HICAS reset as in yea the light was still on and I think some weird feeling in the car was there, but they reset and now light off and I *think* that made it drive better but hard to tell.

Clutch definitely on its way out, its fun being in 5th on highway planting foot and seeing it go to like 5000rpm LOL.

      What brakes on R34 GTT(Europe)

      By Duncan · Posted

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      What brakes on R34 GTT(Europe)

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
