Well, if a gear change doesn't grind at low rpm but do at high, it's probably NOT the tranny; it's the CLUTCH. I've heard this happens on Corvettes too; it has to do with high centrifugal forces not letting the clutch disengage completely, but don't know exactly what's the problem. It'd be interesting to hear from an expert.

Slowing down the shifting eliminates the problem (as rpm drop), but that's probably not what most here want to hear. Subscribed.
