I did a ton of reading on this and was going to place Amsoil in my tranny. However, that being said I stayed with OEM. The new OEM ATF is full syn and that is what I really wanted and didn't have to worry about mixing the ATF either. I just drain it with the oil change and refull 3 quarts. 25 back max for the 3 Q of ATF (DW-1).Is anyone running a different transmission fluid than what Honda/Acura recomends? ie AMSOIL, Royal Purple etc?
