Always a good time for that.

But really, it's the RJM Pedal that claims to reduce wear on the OEM CSC. That, and it makes the car so much better to actually drive. Between the two, I'd recommend the RJM over any aftermarket STS.

 

^ read the OP's post. he describes very clearly the symptoms he is seeing. happens during quick shifts, not normal or slower shifts.

the gearbox in my old G35 was replaced due to bad synchros, as i said in a previous post, so i am aware what happens with fouled parts. and yes, synchros that are totally shot lead to grinding regardless of shift speed.

 

Apologies, I missed your previous post about the G35 transmission; you have experienced what I was trying to explain. Originally you said speed shifting and what was in my mind at the time of the reply from the OP was:

I assumed a 1 second shift was a normal shift and not a speed shift.

But I digress and hope OP gets a new unit!

 

i jus shift slower to avoid the grind i usally dont have the grind when shifting fast at higher rpms (fast n furious mode)
