It is a 2000 GS300. I looked, but it is dark out, and I think I have three. Two up near the exhaust manifold and one down under the car about where the front passenger sits. Does that sound right, three?
Thanks for the help!!
This TSB from the "Filter Manufacturers Council" should aid anyone in the maintenance of their transmission. And... always use a fluid with the same specification that is required from your owners manual or Lexus. Hope this helps!
