Okay, so i've had my car for about two years now, I have 180,000 miles on it. Recently when i've been driving it, it will not go into fourth gear at all. It sucks because I have to drive like 45 mph! When I also start out from park it seems like it kind of slips and doesn't move as quick as it should for how hard I hit the gas pedal. I want to find out if its an easy fix or a major problem? If anyone knows, i'd like to know what I can do to possibly fix the issue?
