Red Beast

hey guys,
my freind just bought a GTCS 2 weeks ago. every time he starts his mustang and drives it within the first 5 minutes, and when he switches to third gear, it makes a terrible grinding sound. it only does it for the first five minutes of driving after its been sitting out. it still has a factory waranty, but the shop is closed so we cant take it in yet. i think that it has something to with the startup, like maybe the engine is giving itself to much gas to warm up the engine and is causeing the flywheel the spin to fast, not allowing the clutch the mesh, but the thing is , is that is happens at low rpms, what u guys think?
thanks
T.C.

synchro kit maybe
My '03 GT did that until I broke it in.. but there was a service bulletin put out in '04 that said to replace the synchros... so maybe Ford is still putting out the same crap.
