Not specifically for Honda, but the new reformulated MTF from Amsoil can replace the Honda OEM fluid. Ordered 2 quarts....will let you know if I notice any differences.

 

Is that too thin? I wonder how well it works...

 

or you can get pennzoil synchromesh at autozone.

 

I'd be afraid to change the tranny fluid with something else when Honda is so ridiculously anal about repeatedly mentioning to never use anything other than genuine Honda fluid in their service manuals...but that's just me. Plus it's a manual, which noone does better than Honda. If it ain't broke..
