r33 gearbox ****ed???

[MANWHORE]

Everytime I change into 2nd or 3rd, the gear box does a small crunch. Is this normal? Like it is just not smooth to put in.

damm i got the same problem i recently changed my clutch and i was told to bring it back for adjusting 2-3 AND 3-4 crunch espically on boost...!

do u think the adjusting of the clutch will help this???

[aKTiVE]

ahaha, yeah i blew my box on sunday morning.

2nd gear would always crunch when downshifting... and now =((((

This must be a common thing on 'line boxes....

had my clutch replaced when i bought the car, so unsure if it did it before that, but the stick just catches a little as you throw through ffrom 2/3 and 3/4 - seems funny that my box should go, as it's on an NA 2litre - bought with little mods, so unlikely to be raced much.

So im thinkin that maybe all our gear boxes must just be wearing - maybe synchros not aligning properly ? ive done 195k if that means anything.... how bout you guys, lot of kays ?

Change your g/b oil with some good quality synthetic oil (syntrax is good)...

That'll fix up the shifting probs!

its the synchros.. they wear... Most r33 boxes i have driven seem to exhibit this.. but can be fine for years in this state.

Can start happening even on sub 100,00km (or supposed sub 100,000km cars )

yeah, worn synchros = quite common, chuck in redline lightweight oil and the problem magically disappears

[Jimbo2000]

in a pristine gbox using redline or similar is it totally silky smooth in every change?

i've got redline in mine and it clunks a little bit into 2nd on an upshift but not a downshift

as Duncan mentioned this is a common occurance with these boxes and your not the only one to have this problem.

Just get some high quality Gearbox oil and it'll gradually get better. Redline Shockproof Lightweight is the best stuff to use IMHO.

As aforementioned, REDLINE is the answer

This is pretty much how it goes, if Redline Shockproof can’t fix your synchro problems then you will have trouble finding something that will IMHO… apart from getting the synchros replaced / gearbox re-built. Its your best (relatively cheap) bet to fix this problem.
