cvrtsniper

hey guys i have a 00 civic ex with an auto trans, my mechanic replaced the trans fluid about 8 months back with full synthetic instead of the honda fluid..now it started to stick about a month back when i started the car and went into gear. the car itself has 144k miles on it.
Also i am wondering if the honda keyless system is still dependent on the factory radio? ive heard mixed messages that its not and that it is.. i have no idea now!
my car never came with a fob so i would really love to find out!
