ur tranny is very easy toservice. a simple drain plug and 2.3 liters of tranny fluid. honda has their own atf but was not reguired this year. servfice the vehicle and while u are at it look at your front and rear motor mounts. this year the front dog bone mount available only fron the dealer, likes to go bad and then take out the rear mount. u may be fealing the shift in the motor at these low speeds. if the car shakes at idle its a dead giveaway. goodluck
