I found a 2500 suburban I'm probably going to be picking up how ever just have a question for you guys. Every 4x4 I've ever had you changed to 4wd in neutral. This one grinds pretty bad and won't go back into park if changed in neutral.... How ever if you shift into 4wd high or low in park it works just fine? Am I doing something wrong or is this truck supposed to be shifted in park.. Floor shifter btw and all my experience is with push button
