I have a very small leak on my 2001 Saturn L 100. I thought about just changing the transmission filter and putting in high mileage transmission fluid. The leak may not be at the pan. I wish this car had a transmission where I could the level like the old but it is more like a manual transmission where you have to remove the top plug to see if it's full. Next question. I got a cheap filter kit but I'm thinking about taking it back and getting a Wix filter kit. Any comments?
