I bought a 2001 honda odessey with 73000 miles the transmission gave up. i have it rebuild now it is 83000 miles transmission starting to slip

have a reputable transmission shop do an analysis it may be an electronic problem or maybe you will have to replace or repair it.

Once a transmission slips-- it is done

Time for a rebuild

THERE IS NO OTHER SOLUTION

It slips,it has done that for awhile,that is an
internally worn out trans

1986-- I would get rid of it

You never install a used trans & $2,500 for a reman
or rebuild, makes no sense.

The whine is a worn out pump or stuck pump valves

I hope you are aware that 1998-2002 Accord transmissions were troublesome, rarely lasted more than 70k miles, and the object of a recall. Should you need to rebuild the transmission, Honda has "Remedy" kit that solves recurring problems. I have a 1998, and this happened to me. If you are lucky, maybe just the torque converter failed, or is worn out, and replacement costs much less than transmission rebuild. Furthermore, these transmissions will positively not work with standard auto transmission fluid. You HAVE to use Honda ATF. Thanks for coming to Fixya.

You can try changing the fluid but the 99-03 Odyssey transmissions were notorious for failure and yours is likely about to die, meaning a rebuild or replacement. Take a look at www.odyclub.com - you'll find a wealth of information on this.

code p 700 refers to transmission control system/mil---malfunction===causes ---wiring --- TCM ( transmission control module)
code p 0730 refers to incorrect gear ratio====causes --TR sensor / switch--shift solenoids---transmission mechanical fault
code p 1740 refers to torque converter clutch solenoid
it is probably correct that dealers will not remove and repair transmissions but I suspect that they are not as reputable as they could be because the codes indicated are repairable in car
I am thinking that there is no mechanical problem requiring a $4,500 transmission so I suggest that you take it to an accredited professional transmission shop and get a proper diagnosis and a quote to replace the faulty tcm and TR sensors

it is possible that you've got an issue with your power steering system, but the noise should be equally noticeable in both forward and reverse. the front differential is inside your transmission and if the differential is worn it will whine. if you pay close attention you may notice the noise when in first gear going from acceleration to deceleration at about 20mph. if this happens, it's most likely your transmission that needs to be replaced.

I went to my honda dealer and while the car was off the service rep pushed 2 buttons and the serial # displayed on the radio. He then looked up the serial # on the computer and gave me my code. Took 5 mins and he charged me nothing. I think the 2 buttons he pushed were the 1 and 6

maybe a change of fliud might help.tranny fliud needs to be changed ever 50K.

Let's start with some facts. Honda, until 2006, didn't build any "trucks". Your Honda Passport actually began life in the Isuzu Rodeo assembly line. This isn't necessarily a bad thing, just no what you were expecting.
Isuzu makes very reliable trucks, but I think you've just had a run of bad luck. My 95 Isuzu Rodeo was retired after 275,000 miles, but only because some moron rear-ended me very severely, and it wasn't worth repairing, body-wise.
My 5-speed manual needed to be replaced at about 240,000, but the V-6 engine had never been cracked open for any major work. It did, however, have a somewhat loose rack/pinion.

The Odyssey has notorious bad transmissions from 2000-2003. You will not get anything on a trade, the trans can be fixed for about $2k. If everything else on the van still works and you like it, figure you bought it again for $2k. I changen my wife's Odyssey trans at 175K miles for $2k and she is happy so therefore I am happy too :-)
