I followed a forum member's experience and experimented with Royal Purple 5w30. It seemed to work well in my 1998 DX transmission. When I swapped to the 1993 CX transmission, I stuck with the 5w30. Shifting was harder, and I at first thought maybe I had not been so lucky and got a transmission that, while operative, had chunkier shifting quality than my stock. I was wrong. I put 10w40 synthetic in yesterday and it's like a new transmission, as good or better than the DX was. And that's why I swapped to a 93K mile transmission anyway (in addition to hoped for FE and cruising speed benefits from the fifth gen CX gearing).

I'm in a little disbelief at the difference.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
