I did a clutch over the winter. Its not like i am a novice working on cars i have done them before and many other things. But anyway stupid me for got to tightin the bolt on the trans that holds the torque arm on. So i was driving last night and i hear a bang on the floor. It came out and knocked a sensor out of the trans. Its right above the Tq arm. Its just pushed out about a 1/4 inch but now i have no speed o and it wont go into reverse! Is this somehtign i can go under the car and push back in and try to straighten the plate that holds it on? Does it have to go to a trans place to get fixed? What else could i have messed up? thanks for any help you can give me
