lol, i had to get my synchro replaced a few weeks back on my stage one R33 GTR. 3rd to 4th was crunching on high rpm change ups (weird huh?) so sent it to get fixed.
At the same time i ordered some Redline Shockproof Lightweight box oil to put in.
the box has been problem free for approx and super smooth for the 1k miles ive done since. I too find the car doesnt like being put into first when cold but i find if i engage reverse before trying first it goes in problem free
