I am getting stuff together for a tranmisson fluid change. I have been using Pennzoil ATF+3, but I don't think it is made anymore. From what I have read it has been replaced by ATF+4, which is supposedly backwards compatible and is a synthetic. I could buy the ATF+3 by the gallon last year, but I don't think ATF+4 is packaged or sold by the gallon, only by the quart.
Where do you guys buy you transmission fluid? Is the Walmart brand OK to use?
