Sounds like you need the updated engine computer for harsh shifting. Look up under the glove box at the computer. Number should be 89661-02K21 if not, you need the update. It is an 8/80 warranty item.

check the fuel filter and when was the last time you had a tranny service done and a tune up also check the drivebelt

there is a solenoid that releases the shifter when you step on the brake pedal.there is by the shifter a little tab that can be popped out with a small screwdriver,and using your key,put into the hole and the mechanical device will release the shifter.
it is called a shift lock override
