For P1739 , replace the 3rd clutch pressure switch and do an ATF drain & fill(use only Honda fluid). For EVAP (P1457) best to have that diagnosed at a shop that's equipped with tools and info necessary. Dealer might be best choice , depending on what's available in your area.
Thank you for your help...i have one more question?...Can this possibly mean that my transmission is slipping or going bad?
That pressure switch monitors clutch pressure (for that hydraulic circuit , to help ease the 'shift shock' when gear changes. Probably , you don't and won't feel much of a difference short term.No , it doesn't mean the trans is going bad. I haven't changed that many on Accords' , but I've changed quite a few on Pilots and Oddyseys , with no other noticable effects to the trans.
