2002 HONDA ACCORD SHIFTS FINE BUT WILL SUDDENLY SHIFT INTO FIRST GEAR WHEN GOING DOWN THE HIGHWAY. WHAT'S THE PROBLEM? CODE SAYS TRANSMISSION SENSOR

SOURCE: 1998 HONDA ACCORD TRANSMISSION

If it is an automatic tranny, i had a similar problem in a 1989 CRX with an auto tranny. Your problem could be your torque converter, You may have knocked it a 1/2in or so when you connected and bolted the motor down to the tranny, in doing so you like i said, budged the torque converter out of its appropiate place. So it may or may not be grabbing like it should.....

If this is the problem, remove the motor from the tranny, (and you might as well replace your seal while at it if you havent), adjust the converter back into place, until it grabs ahold of the tranny, you will feel it, shove it back there. Take note of how it moves and what makes it come out of place, with that in mind, REPUT the tranny back in, bolt it down. Prey thats the problem

First thing to do,try to pump your clutch before you shift into 1st gear then if you feel makes better, most probably you have problem with your hydraulic clutch system, check the clutch line if there is an evidence of fluid leaking or it could be internal leak.

Second thing to do, check your transmission oil, may be it' s too old or you use a thick oil thats why when cold its hard to shift then when the engine rich the normal temperature(warm) the oil become thin and the shifting will smooth. Remember the very old oil become thicken and the purity is gone and can cause of hard shifting. in this regards i suggest you to change the transmission oil and check the used oil if there is small peace of metals, then you are in big trouble,

You have a bad transmission control module (TCM). It is under the passenger side front floor mat. You can get rebuilt units off Ebay, whatever you do, don't get a used one! They are all bad. If you know anybody that does electronic repairs, you can have them replace the big 220 uf capacitor on the PC board in the TCM. It's a two dollar part and a ten minute job but you have to know what you're doing.

Has anyone change the transmission fluid and used anything other than Honda ATF-Z1. If so, have the fluid/filter changed in this car and use only Honda Fluid. This is the only fluid that you can use in a Honda. Even if you have used the correct fluid an fluid/filter change may help. If that is not the case then I suggest you seek out a trusted professional.

the first common possibilty would be to check fluid level, if the fluid level is good, I would recommend changing the transaxle fluid and filter. if this does not correct the issue, a professional transmission repair person will need to diagnose for you, good luck!
