Shifting from 1st to 2nd gear clunking slipped out of gear transmission problems.
I have only owned this car for 3 months. It has 4400 miles on it and the manual transmission is acting up. Sometimes I cannot get it to go in to gear, usually 1st, 2nd, and reverse. It will occasionally jump out of gear with normal operation. This car is very unsafe with this problem. I live in the dallas metroplex, with the stop and go traffic sometimes a driver doesn't see the cars in front stopped and you you have to get out of their way. With this problem I can guarantee that I would get rear ended in that situation. Even after sitting at a light I sometimes am getting honked at since I cannot get the car into gear. I believe this to be a very serious safety issue as well as a huge annoyance. This needs to be fixed.
Transmission jumping out of gear during moving, impossible to down shift to aid in engine braking or dodging/avoiding obstacles.
