I'm not asking what kind is the best tranny fluid. I've got no complaints about the shifting in my WRX, and have 34k on the car and just want to change the tranny (5 speed) and diff fluid and put in fresh OEM stuff. My problem is that my local Subaru dealer (where I managed to spend frickin $65 on just 1 oil filter, air filter, and fuel filter...) doesn't sell tranny fluid. They said that they get theirs in big drums and have no idea what manufacturer it is. I went to one of my local auto parts stores and the ONLY 75w90 NON synthetic oil they have is some no name stuff that I've never heard of and am not completely comfortable putting in my car. I'm not sure what to do. I'd like to at least use a brand that I'm familiar and comfortable with like Mobil or Castrol, but don't want to do the synthetic thing. I don't want to have the dealer do it because all of the service guys seem like weasels and I much prefer to do my own work. Any help?
