Question: WONT SHIFT OUT OF PARK I JUST CHANGE THE BRAKE BOOSTER

when you changed the booster, you may have disturbed the adjustment of the brake light switch which allows the shifter to release when you apply the brakes.

Mine did the same thing. I now, without changing the brake booster switch under the steering column and dash, just hit the brake as soon as I try to shift outta park. Its a timing thing. Works everytime.
