Crunching into 5th


Recommended Posts

Quick update. Just did a first track day after the gearbox fluid change. Not even one occasion of crunching detected. I was also a bit more gentle when shifting from the 4th to the 5th.

Being same "gentle" before the fluid change cause crunching. So it is a bit better for sure. Plan is to do trackday or two and change the fluid again.

Which fluid did you finally use ?

Motul Gear 300 LS 75W90 only, no additives. 

@Paul_D I was there just helping (i.e. watching 😂). Friend of mine is a certified race cars mechanic and has some professional tools to do it. He did it.

I think you'll find the plastic pads on the shift forks are buggered.  I just had a 3rd & 4th issue on mine and that was the fault, SSC replaced the plastic with a brass pad and installed an LSD while the gearbox was open and its perfect now.

Thx for the info. So it should be checked when integrating LSD :)

Aren't these cars still under warranty? 

Yes, but I wouldn't put back plastic part. My thinking is if this was a problem on a new car (well, 1000-2000 miles), it will be repeated in 1000-2000 miles again.

Just add I didn't want to put the plastic part back in either.  Had I pushed for warranty I am sure they would have put it back to OEM spec and I would have been back there in another 4000kms.  By changing the plastic parts for brass pads the problem is fixed permanently.  I used the opportunity to install an LSD but I probably would not have bothered if the gearbox didn't need to be pulled to fix the shift fork pads.

Are those brass pads some standard part others could order or is this a custom solution?

Definitely not standard, standard is plastic.  If you're not in Australia you could send the shift forks to Simply Sports Cars in Sydney.  They could possibly supply brand-new ones with the modification.
