Ok, put the car in reverse and then accelerated back but I didnt floor it. After I let go of the accelrator the car felt like it braked on me. It slowed down quickly and the noise got louder as you go faster in reverse. After this happened I had a hard time going forward or reverse and I slowly drove back to my home around the block. Now there is a more louder noise like someting hitting something. The noise is present now even when Idle! Im thinking my tranny went out but the teanny shifted perfect prior to me backing up that way.??? IM confused
