George,
Tremecs and T5's are internal rail type, so shifting is usually a smooth, easy task. About all one needs to do to improve feel is perhaps an aftermarket shifter, such as a Pro 5.0. This will tighten up the gate, and give a slightly shorter throw.
Now, you really wanna feel a sweet shifting car, hop into a Honda S2000 or a Mazda Miata. Too bad they don't come with V-8's!!
