Does anyone have an idea as to what could be wrong with the ol'mans roo? He slid off the road on Christmas eve and got stuck, he tried to rock the car back and forth to get out, now its stuck in 4th gear and cant shift into any other gear. Whith the car jacked up in the air and the car off and clutch out he can spin the front wheel with his hand. It also pops hard when shifting in and out of 4wd. Would be real greatfull for any help or ideas.
