I have a 1989 Sentra 4 dr sdn. It has pwr,starts,etc, but it won't go into gear.

What is your question?

Hi! My car is a 1989 Nissan Sentra 4 dr sdn. It has power, starts, etc., but when I go to shift it into gear, it shifts but it isn't going into gear. Is this the linkage, and if yes, is it easy to fix? Please let me know ASAP as I need to get her up and running. What a trooper. Over 300,000 and she is still getting me where I need to go.(Except for now that is! lol) Thank you for letting me know. I look forward to hearing from you. Kristen
