Transmission Fluid - really that hard?
I've read just about every post on this forum and others about recommendations for Transmission Fluid. Here are the two take aways for my 2000 Boxster S:
1) Correct oil for this is a GL-4 75W90.
2) Using a GL-5 in this transmission is BAD and will wear the yellow bits.
3) But, everyone uses a GL-5 (Swepco, Redline, Mobile1, etc) because that seems to be all that is available.
This feels very incongruent. What, pray tell, am I missing?
