Is This The Same For Anyone Else? Gear Stuff

[sl33py]

In my R33 GTST S2:

If I change into 5th from 3rd or 4th when the engine speed is 5k rpm or higher, I sometimes get grindies. I haven't had the car very long (1 month). Scared the crap outta me cos I haven't had the car long. After that initial "wtf!" I try to change again and it goes in, either because the engine speed has dropped, or for whatever reason.

Now I first thought I wasn't clutching properly or that I was on the gas again too quickly, but I've since repeated it several times and I'm now sure that neither of those is the problem.

After a bit more of a play around, I've found that I need to be fairly... "deliberate"... more so when changing into 5th than I need to be going between the other gears.

The car's about to go to a mechanic so I'll ask if he can tell anything weird with the gearbox and maybe have the oil changed anyway (cos I don't know when it was done last since I just bought it).

So anyone else get this kinda thing?

I have the same problem however mine is going from 2nd into fourth and fourth gear crunches for some reason. Only when the engine is over 5000rpm though. If i go to third then fourth it is fine but 2nd to fourth is when it plays up. I thought the same at first with the clutching but after trying a couple of times i knew something wierd was definately up.

Have the same problem, giving the car a flog changing from 4th to 5th, dirty big grind. No idea why!

Seems to a fairly common problem that happens to skyline boxes over time. Usually manifests as findiing to hard to shift from first to second when cold. Some people have speculated its the synchros wearing out and not being able to keep up with the rate of the change.

Fortunatly however, alot of people have done gearbox oil changes and this tends to fix the problem or at least to a large degree providing you havent overly damaged the synchros, gears etc.

Try some redline shockproof, or some castrol fluid with nulon additive for shock proofing. Can't hurt to change your gearbox fluid anyway!
