99 F250 PS Shifting Hard????

[RanchStroker]

Hey guys,

I have a 99 250 that is shifting hard. First this if my first auto tranny so im fairly lost with it. It has a new rebuilt tranny with a shift kit installed about 10k miles ago. I dont drive it very much but will be soon so would like to get it figured out. It seems to not shift nearly as hard first thing after sitting for a long time but as it gets driven longer possibly hotter it gets rougher and rougher shifting into 3rd and OD. If I manually shift from first to second and push the overdrive from off to on before it gets there is seems smoother. Also if I accelerate hard it isnt nearly as noticable. I have checked the fluid a few times to and it is plenty full. I am not so sure it isnt to full. The fluid goes a little less than 1/4 inch above the plastic piece on the dipstick. Is this normal?

Any thoughts or ideas would be greatly appriciated! ! ! !
