Hello everyone, im new to these forms, but need help, i recently bought a 2004 audi a4 for $400, nice car starts right up, problem is it wont go into gear, and i have the code for "transmission output speed sensor no signal". The car is front wheel drive automatic, i can get it to go in P and N only, it wont go pass N without forcing it, and wont stay when it does. When in reverse the car does not move but can hear something spinning like the bell housing or something, i need help figuring out what the problem is, any ideas or suggestion of where to start will be appreciated
