2003 honda oddessey 3.5 codes check-engine-light

Question

have a 2003 honda oddessey, It has about 141k . Van has been good to me and my family until couple of wks ago. I was exiting of the fwy and my van just down shifted really hard. Frm my experience. I knew it wasnt the transmission. But it was something related to it. It was all electrical. I checked the code and it came up to something with the pressure selinoid which is common for those years. So i replaced the oil pressure selinoid and the atf pressure selinoid. Those are the 2 main common problems for the 03 and 04 oddessey's, 100,000 miles replace those 2. So i replaced it and everything went back to normal for about 2 wks. After that the check engine light came out and the code came out to p0730 which could be low on atf fluid, or dirty atf fluid etc. But i always keep my van well maintance. So what should i do now? I do my own work but im not a 100 percent mechanic. Im about 60 percent of knowledge and skills with cars but this van is really frustrating. Can someone give me a good advise?

Answer 1

P0730 Problem in shift control system

Have you replaced the shift solenoids? There not much you cando unless you measure the pressure of the clutch, The only fix would be looking into a rebult transmission
