Transmission Grinding: Am I doing something wrong?

I'm currently running a Koup SX 6 speed and here is my problem. Whenever I do a 3 - 6 shift my transmission grinds, in fact, if I do a 4 - 6 shift, my transmission grinds. So I'm wondering, am I not supposed to be shifting from third to sixth (say accelerating onto the highway then shifting into 6th to cruise)? I was always under the impression that this was okay. Does anybody else's transmission grind when doing this or should I get it checked by the dealer?

Not the first time I am hearing about a tranny problem... we've replaced three of them, now.

Do you have cold weather mats in your car? possibly jammed up behind the pedal and not allowing it to fully depress? Are you short and maybe not bottoming out the pedal? Simple questions, but it's amazing how many times someone thinks they have pushed all the way and there is an inch of room left.
That recall is for the front strut boots falling down, and is just some small adhesive pads on the boots to keep them where they belong. It's mentioned elsewhere in several threads on the forum usually in "knocking sound from the front end" threads.
