its pretty simple, once you pop knob off and pull the cover off disconnect the cig lighter... then when you undo all the screws pull the old shifter off. put some sort of cloth or something to keep the crap out of tranny, while you clean the part where you will put on the RTV gasketsealer/maker on and then slap your new one on and reverse the deal. You will love the new feel but be prepared to drive your car like crap until you get used to it. everyone says AH ill be fine... then they come back... lol man i have missed a few gears but now i am ok.
good luck and let us know
p.s. also make sure the screws on the new shifter base are adjusted too.
