FYI, while stopping at my local parts dealership to buy some honda genuine manual tranny fluid, he said that to never put synthetic tranny fluid in our trannys. they said something about the tranny syncros spinning too fast and it would eventually make the tranny grind in every gear. there was a customer with an 08 si who put synthetic tranny fluid in their car and it fk'ed up the syncros and he had to pay 2600 to get it fixed because they wouldn't warranty it (because of the synthetic fluid)
