Rep Power: 0

Ok, I have a 1991 dx auto runs great.Just changed tranny fluid,Throttle valve cable to trans feels right as far tension/adjustment,so...why does it shift hard into first and second but not 3rd or 4th and it only does this sometimes.Seems to do it more when giving it more throttle and sometimes when coming to a sudden stop it shifts into 2nd pretty hard.But if I baby the gas pedal it shifts smooth,WTF is going on.

Also, it sometimes has a slight hesitation in the lower rpms of 1st and 2nd,like its not responding well to the throttle and then all the sudden it picks up speed.When it does this 1st and 2nd always shifts hard,but its not slipping it just feels like a hesitation.WTF.

timing is on point.
cv's are both bad.
front motor mount is bad.
new fuel filter.

Help.
