What up guys. Well I am in need of some help if anyone can. I went to church this morning and the car sat for hour or so. After church started it up and put into drive, gave it some gas and it lighty jerked into gear. Well later that day I was driving around and the car started shifting hard through all the gears. Is this a good indication that the tranny is about to go or what? I know nothing about transmissions. If it is going out should it be throwing codes or just go out?
