How to replace overdrive relay on 2002 alero
There isn't an overdrive relay. There is an overdrive solenoid. It takes about four hours to replace. You better have manuals and patience to do it. otherwise you will mess up the transmission worse than it is already..I really don't recommend a nice to do it. When you take it apart, there are parts that fall out. You lose them or don't get them back in place, a transmission rebuild ,plus extra parts are in the works for you.
