1. Remove the negative battery cable.
2. Remove wires on the starter.
3. Remove the two mounting bolts. They have 15mm heads. (The top bolt is hidden and hard to get to.) You may have to remove the solenoid (on top of the starter) to get to it.
4. Remove starter
Replacement is the opposite of the removal.
There is a video on U-Tube showing where the sensor is and how to change it. It is above the starter

If you really don't know where a starter is, I suggest obtaining a repair manual.
The starter on the 2002 Saturn vue is located on the front underside of the engine, follow the positive(red) cable from the battery and it should connect to the solenoid which is part of the starter.

You do not need to change the transmission fluid in the Saturn vue. It is a sealed system and only needs to be replaced when the trans needs rebuilding.
