R34 Gearbox Drama

Hey everyone.

I just recently got my new 34 GT from top secret imports in blacktown. When i test drove it before compliance it was an awesome machine. Gearbox was fine from 1st to 5th.

After waiting close to 3 weeks for compliance and rego i get the car back take it for a drive to get some petrol and on the way home changing into 4th at about 4000rpm or above no matter how hard i push the clutch into the ground it crunches in 4th and 5th.

at lower revs it pops into 4th but still crunches into 5th no matter wat. I think since compliance they have stuffed up the sychros so I have since taken the car back and they are looking into it but i thought i might do some asking around to see if anyone has had a similar problem. (tried a search nothin specific enough).

Anyways my questions are,

What could they have messed up with on compliance?

Was it just not put back together properly so the clutch doesnt release the gear properly?

and why wouldnt this affect the other 3 gears?

Anything would help give me some piece of mind.. Been nothing but a headache since i started compliance and i dont want to think i have bought a bodgey skyline after drivin it so nicely before.. Lost the car for another 4 days too :P

And may as well ask while im here.. what does this sticker mean.. its like a green clock with the 3 highlighted and some writing around it

Parking permit???

Im sure someone took it for a thrash before pickup; basically downchanging hard and snapping gears *no f*kkkkn respect for other peoples property*

Cmon how many times have we heard of mechanics and apprentices writing off cars? I know a few and the stories are all the same.

yeah sounds like it's a synchro issue.

Would they even touch the gearbox in compliancing?

Hope you sort it out

My 34 does this also, and has for the last 2 years. I don't think its a major issue so haven't worried about it too much as its not getting worse. Check out these threads on the same topic.

Possibly when they changed the gear oil at compliance,

The oil they used may be too thick, if the synchro's where abit warn the thicker the gear oil, the harder the synchros have to work to cut through the oil to mach gear speeds.

I was also told by the guy that complied my 34 to change all the fluids again due to them using poorer quality and cheaper fluids.

100% agree; use redline superlight shockproof. very light and even compatible with getrags which need an auto fluid.

      @Haggerty this is your red flag. In MAP based ECU's the Manifold pressure X RPM calculation is how the engine knows it is actually...running/going through ANY load. You are confusing the term 'base map' with your base VE/Fuel table. When most people say 'base map' they mean the stock entire tune shipped with the ECU, hopefully aimed at a specific car/setup to use as a base for beginning to tune your specific car. Haltech has a lot of documentation (or at least they used to, I expect it to be better now). Read it voraciously.

      I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.

      @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation.

      If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
