I have a 1987 Honda Accord it has 187000 miles when driving along hiway the overdrive kicks in when start up a slight hill then off when going down hill it seems that it works backwards from the way it should. I don't have a repair manual for this car so just hoping some one could tell me what might be wrong thanks

Ok so im not 100% sure on this but when goin into over drive, your car is in 5th gear right??? if so then one possiblity is that the gear itself inside the tranny is just worn out which is causing the gear to slip. so that means you can either replace the tranny or rebuild it.

Well this is an automatic transmission and I know that the od is operated either by cable or maybe vac. Hose or 12volts thanks

ah ok well then its probly a vacuum problem cause i know these old cars run on alot of vacuum stuff an i know that cause i own a 82 civic lol so maybe you should get a repair manuel for your car so you can check all your vacuum lines
