I feel like a real newbie even asking this. In the old days ( I'm 60) There was no question. Trani Fluid or Power steering fluid went in the reservoir.TODAY with all the proprietary crap these cars have, I'm not sure whether it's a gimick or to really abide by it. So the power steering cap says ONLY HONDA FLUID. Should I take that serious? I was going to suck out the old and replace with new. Kind of a 200K mile gift. So what say you? Buy generic fluid or, like the rear Diff fluid, is the fluid magical?
