hey i was driving the car when all of a sudden my shifter just went up and down not going into gear. i looked under the car adn the shift cable had popped out. i tried to pop it back in and it popped back ou again. it looks like it shold slide in a u shaped holder in some grooves. now my question is am i missing some kind of c-clip to hold it in there in the groove? im guessing it poped off. can i go to the store and get one?? this is just my luck, thanks
