There's dozens of variables.. The TICK master might help, a stronger clutch might help, a rebuild with new synchros might help, ad-nauseum.

With a stock clutch you SHOULDN'T have any problems... as long as your clutch fluid is clean, there are no air pockets and your trans is in decent shape. The only problems I have ever encountered have been when you upgrade to an aftermarket clutch. Stock clutches shift like butter if everything else is good.

Nope.

All gears? Your clutch may not be releasing properly. Did you measure and use a spacer beneath the slave accordingly?

Consistently happens going into specific gears only? Time to refresh the trans. like Mike said.

A push style clutch release bearing has a distance spec. it needs to be away from the pressure plate fingers.

A pressure plate's fingers can change position based on disc wear (plate gets closer to the flywheel, fingers go out) or when the flywheel is machined (PP becomes closer to the engine) and not every PP is the same.

In your case with stock parts, this wouldn't tend to be a concern. So is it specific gears?

make sure you have a heat sleeve on the braided clutch line and keep it well away from the headers.

A few people have said rebuild with syncros. The syncros are what allow the gears to line up when you push the clutch in and after miles of hard shifts and wear they grind down and wear out plus I believe in the Fbodys T56 they are plastic so they wear even faster. Time for some new sycnros at least probably.
