Question, my son has a 05 Crossfire Automatic Base, while pulling in a parking lot, he went to put the car in park and the shifter just sailed through the gears with no catching, Free rain.... is this the Transmission or just the shift linkage the connects the shifter to the Transmission? If it is just the linkage, is it visible and easy enough to fix or does the tyranny need dropped? Please refrain from any smart comments please...I could really use some help!!
