i have a 90 with an auto tranny. it has a lot of troubles shifting into drive or reverse or any gear for that matter. when i go to make a three point turn i shift it into reverse and the light doesnt come on and my car wont go backwards. the same thing but in reverse for drive or any other gears. my car also sometimes wont shift into park and i cant take the key out because its not in park. the key lock keeps my key in. what the hell is going on. is this just a sign of a going trans or can i fix it.
