hello fellow odyssians. so i started up my 01 odyssey yesterday and almost immediately my tcs light came on, my check engine light came on, and my d4 light started flashing away. of course the van had trouble shifting, too. after i turned the car off and back on, the tcs light went off and the d4 light stopped blinking. the check engine light stayed on though and the van was still acting funny. i took it in to a shop today and they told me i need a new tranny.
i bought the van 2 years ago. the tranny was replaced about three years ago. i have the receipts to prove it. the owner actually had to take it back to the shop a couple weeks after it was replaced because the the tcs light and check engine light came on. it was also having trouble shifting. the tech pulled the following codes: p1491, p1738, p1739. they ended up replacing the the 2nd and 3rd clutch pressure switches.
did the transmission really need to be replaced? is it possible that it was just the pressure switches? sounds a little odd to me those things needed to be replaced just 2 weeks after the new tranny was installed.
it sounds like i've got the same problem now. unfortunately i don't know the codes they pulled from the computer today. they cleared them, too. i'm going to call tomorrow and see if they can tell me.
here's the kicker. after i picked it up from the shop today, the thing hardly shifted out of first gear. if i turn it off and then back on, it starts working better. then after a minute it will not shift at all. this cycle would continue until i just gave up trying to get it home and parked it.
so that's where i'm at now. sorry for the essay. i would greatly appreciate any help. thanks!
