NC bad habits

G'box change into second very difficult when cold, no change from 17k to 35k (current). Tried Castrol 75W - 85 VMX, then Mobil Delvac Synthetic Gear oil 75W-90, no particular difference w.r.t. change into second. Mobil is expensive. Had to purchase 20l from distributor - so will keep me going for a while. Seems to work well in the LSD. If you find a solution by simply changing oil it would be welcome news.

Nulon G70 additive helped a little. Extremely easy to put in so i would recommend since it's only $15

I purchased my NC in 2009 without a test drive, left my NB at the dealer and got a lift to the airport, one thing lead to another and it was almost three weeks before I picked up the new car and I will never forget the shock and horror that I experienced when I first drove it, admittedly my NB was running redline and had I had just fitted new boots (top and bottom)
but this new thing was akin to driving Tomas the Tank Engine on a bad day, a few shifts at normal running is enough to settle everything down and it only gets better from there on. An up-spec oil may fix the cold shift issuses but I doubt it, and on the point of bundling the NC gearbox in with past 6-speeds, If my memory serves me correctly the G/box has been totally re-engineered with triple syncros on the first four gears, a one piece shift linkage and repositioning of the gear lever for a more direct feel.
Enjoy.

i remember reading on Mnet a guy cured the gearchange issue but it involved pulling the gearbox and re-doing the thrust washers???

rev hunting solved -

I picked up some throttle body cleaner this morning, took off the intake and realized I have no air filter!? don't know what happened there. cleaned the throttle body and now no rev hunting, it was filthy. will be getting an air filter before my next drive

cheers

either a careless mechanic, or young guy removed it to get the extra 0.08kW of power.
I'm assuming the NC has a hotwire MAF? If so, I would also look into gently using some CRC MAF Cleaner

lol @ dan, yeah i found a brick in the airbox, the throttle body is doing its job well!!

I bought it off an old bloke. I have not had it serviced yet as it has had a service 4000kms ago. Roadworthy was included in sale to so i am not sure what has happened.
