i just bought a 89' nissan 240sx. when i bought it i found out it doesnt go in reverse cause it was in a fender bender and knocked something loose. it worked fine befor that but when the person tried backing up after the crash it wouldnt go. i think its just the linkage that got knocked out of place but im not sure how to fix it. im getting tired of pushing it out of my parking space. if anyone has an idea on how to fix this plz let me know.
