Hi im new on here but i got a qustion you guys out there might be able to shed some light on. The other day i was at Oran park and first lap i went out i wasn't stressing the car too much but i came onto the straight in 2nd gear, shifted to 3rd and when i went to go to 4th roughly halfway down the straight, i had the clutch completely compressed, shifted to neutral and almost if i was flatshifting, the gearbox grinded violently and would not go into gear. This only would happen if the car was at running temperature and roughly above 5000rpm in 3rd when shifting. This continued to happen whenever i tried to shift throughout the day unless i shifted to neutral, released clutch and then compressed clutch pedal again, then went to 4th gear... Does this sound like synchro's in 4th gear have gone? seems unusual to me...NEED HELP!

THANKS!

Chris.

Looks like gearbox due for rebuild...

Mine likes to pop out of 3rd gear when downshifting and heel-toeing fast during corner approach. Not fun revving up on corner exit only to find the car's actually in neutral...

Awesome, ill give that a go. Also Gearbox oil coolers, I think this is a pretty uncommon thing but they do exist for the RB25 gearbox dont they? In my merc the tranny cooler is located under the radiator element, inside. Dont know if this is the same on the R33 but id be interested in whacking a extrnal cooler for it in.

Any info on such a thing?

pretty expensive.

I bought 4L for $100 from CRD in sydney.

not sure who else sells it.

manual box oil cooler is not common.

on auto skylines, the gearbox fluid is pumped through the bottom of the radiator.....

I don't know if a gearbox oil cooler will stop the crunching..

I'd try the good oil first, and if it still does it, might be time to refresh the box.

      I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
