Transfluid. For 2010 Pilot AWD ATF-Z1 OR ATF DW-1?

[Corvettezr1zo6]

I’m getting ready to do a trans fluid change in my pilot, I went to CARQUEST parts store, and they have both Honda ATF-Z1 fluid and a newer fluid for Honda called ATF DW-1. So before I buy it wanted to ask is there any difference between the two? Is one any better then the other?

DW1 is the new synthetic ATF from Honda it is inter-mixable and backwards compatible with Z1 fluids in the Honda transmissions designed for Z1 ATF. (2011 or older for the Pilot).
2012 Pilots come with DW-1 and it is not recommended to intermix Z1 in transmissions shipped from the factory with DW1 according to my dealer. Also, per my dealer, Honda has discontinued production of Z1.
