97 olds bravada. a few weeks ago i had to replace the ignition switch and neutral safety switch. then for the past few days the gear selectors button wont press in when its in park. i can get it to work if i jam the shifter around hard or crawl under and wiggle the lever on the side of the tranny. i have no trouble starting the engine. so could my neutral safety switch just need adjusted? or what else should i check?

 

no ideas?
