Honda has introduced a new 10-speed that uses conventional planetary gearsets - which MaxLife was designed for. I've used MaxLife and Castrol IMV in Honda 4/5 speeds to no ill effect.
DW-1 and Z-1 are weird beasts, while the traditional Honda automatic is a AMT, there is still a torque converter. Honda does call for Dexron-II fluid as an "emergency" replacement for DW-1/Z-1 but warns that shift feel might be different. They aren't smooth operators.
