My 2000 was notchy and deliberate and so is my 2005. The stock shifter is perfectly fine for street use. Let me put it this way: It's not the smoothest or fastest shifter, but I never wonder what gear I'm grabbing. And it never fights going into gear.
On my 2000, going to 3.73's made a BIG difference in fun factor and SOTP feel. Now, going from 3.55's to 3.73's, I'm not sure how noticable it would be. Problem is, after having the 3.73's, I can't imagine driving at 75-80 every day with 4.10's.
Also, with 4.10's and other mods, it wouldn't take much to start having traction problems with the stock 235 all-season tires.
