my accord was shifting hard thru the gears but i bought a gallon of the transmission fluid and some lucas tranny oil and i drained the 2.5 qrts out filled it back up drove it for a few, went back and changed it again and added the lucas and it fixed the hard shifting but it still wants to rev up when going into 4th, could this be a solonoid issue, i changed one solonoid but couldnt really get to the other one and didnt feel like pulling it all apart just to put it on, any help greatly appreciated
