2002 honda odyssy, tranny not shifting properly and will free wheel under load

Is the tranny actually in Park? Make sure the shift adjustment is correct. If should start only in park or neutral in any other position shift adjustment is incorrect.

Hey Barry, I included an image of tranny, some are external but some are internal , even I rearly test my own tranny solenoid due to the complexity and the chance of getting it wrong , there are a lot of tranny shops that will scan your tranny FREE and give you a report . buyer beware ! make sure the shop is of a high reputation.

this is normal on hills.
read the operators guide. (The A/T blues) (jack car wheel up, to free it, any rear wheel if cant move out of part)
People in San Francisco know this all so well, at the curbs.

or someone put car into park moving
and bent the parking pawl in the the tranny , oops,. that is damage.

Check fluid level worse case gears aren't sincrenizing properly tranny shop can tell u that when they check fluid level but sounds like tranny going out or your clutch if has one I'd say clutch first before tranny gears if manual tranny if auto then fluid or tranny needs serviced

we need more descripcion to help you fix the problem

If its stuck in reverse then it wont start, this could be a bad tranny or the shift cable broke or came loose, theres a braket under the dash that holds the shift cable before it connects to the shifter linkage arm and that braket sometimes gets loosened up and the other problem is the shifter tube may have broken. a good way to see if its the tranny or the shifter asm is to get under the truck make sure to block wheels and put e-brake on. dissconnect linkage at the tranny and move the selecter arm on the tranny, if it in reverse then it should move o click in one direction which is park and the other way is into neutral then drive and so on, try to get it into park and seeif truck starts, if it does then its not the tranyy but rather it the shifter, another thing before doing that have someone turn key on but dont try to start it just move the shifter and se if it moves the arm on the trany, you will see this from under the side of truck on driverside. good day.

This is a known problem for Honda Odysseys. The fix is to replace the rear vent window motors or live without their ability to open.

If it is a front wheel drive. it's under the hood. lookto the back of the engine to the tranny. where the shift cable/linkage goes to the the tranny.it's right under that. you will have to disconnect that , remove the arm, and there are two small bolts that hold it on. you might have to pry the old off. if it is a rear wheel drive it's under the car. again follow the linkage to the shift lever, about the middle of the tranny, drivers side. disassemble the same way. the new shift selector will come instruction on how to replace and adjust

There are two speed sensors. One is on the tranny under the throttle bosy and one is under the tranny.

This is the one under the throttle body

This is the one under the tranny near the right wheel.The Countershaft speed sensor is the best bet. i replaced this one on a 1995 honda accord with flashing d4 and after replacement it was gone.the part will be about 125 bucks.

have you thought maybe it is finally working proper now! if torque converter wasn't locking up yes then I would say something wrong!
