There is a fluid level plug on the side of the transmission that you add the fluid through but this vehicle should not need to have fluid changed unless driven hard. Here is a picture.
Well I just bought it from a friend who has never had it changed and it is just under 100k miles! And the car is hesitating into reverse and very slightly between gears, so Im pretty sure I need to do a full flus and filter change (since it hasnt ever been done) But how do I get all of it out of the torque converter? and do I do it with the car running or not?
