Gears crunching when shifting cold T56 gearbox

I've had my Clubsport R8 VT2 for just a few months and I've noticed that the gears crunch a little until the box is warmed up. I'm based in the UK and it's -5 degrees C right now which has made the problem much worse. Is the Tremec T56 known for doing this?

Pretty common. Check the stops and use a synthetic oil. The oil can help a little.

MAINLUBE oil reduces this symptom.You get what you pay for in this case with Mainlube,best oil out across the board.

Try double declutching until the box warms up. IE drive it like it had no synchromesh on the gears. If it was doing it when warm, I would say that your synchro was on the way out.
