my power tnt is not working properly,it works just as supposed to in the up possition but when i go to tilt motor down the TNT motor runs but the motor free falls untill it reaches the trim part then it trims as its supposed to.TNT motor is new as of last summer.i have tried everything i know to try...

i cycle the TNT up and down 4-5 times as specified then check and add fluid if needed,when i remove the fill screw to check fluid level it releases air and i usually get some real foamy fluid leaking out,like its not self bleeding.does anyone know what i should look at to correct this problem,thanks in advance!!

yes i fill it when its all the way up.i have taken the TNT apart and put all new o-rings in it.the only ones i didnt replace was the stuff inside the hydrolic tubes because i learned after i had already taken apart the TNT and had most other parts replaced i noticed that my motor had a diff year and HP TNT on my 1995 88 spl and orings where only things that was the same.all seals and such for hydrolic cylenders are different.
