1996 GMC Yukon Q&A

1996 GMC Yukon Question: WONT SHIFT OUT OF PARK I JUST CHANGE THE BRAKE BOOSTER

THIS PROBLEM HAS JUST OCCURED WHEN I CHANGED THE BRAKE BOOSTER AND THE MASTER CYLINDER -
Answer 1
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. Roy -

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. -
