i have a 98 accord 4cy sedan with 160xxx miles. the issue im having is the transmission shifts hard/slips from 1st - 2nd gears and back down. the car drives fine when its cold for about a hour or longer sometime all day, but once its warm this issue shows up, i dont plan on changing the fluid becasue i bought that car recently and i dont know what regular maintianance the pervious owner did. i took it to Aamco and the guy said its low pressure in the transmission when the car gets warm. he said it could be a bushing thats borken or make my clutch is burned out, car has no CELs. what do u guys think?
