fluid type for A-518

It just seems to me like he told his workers go check out that dodge and try to find other problems with it rather then transmission and maybe we can get him to pay us to fix them.
They gave me a 2 year warranty and i have it in writing on the recipt they gave me, so they have to fix it, im niot going to let them get away with sending me off when its running that way, when he called me back after i told him i thought they were wrong and that he should take a closer look, he calls back and says ya there is deffanatly something going on with it and whatever it is could burn up the transmission, and i said ya exactly thats what i brought it back to you, and he said well ill pull it on a rack tommarrow and ill call you and let you know what i find, but i think its your engine.
What could my engine possibly do to make the transmission growl and howl and whine and vibrate? it sounds to me like they messed up on installing it or didnt have it balalnced right or didnt have the torque converter clocked right or something, because whatever is going on with it im bout 99 percent sure it is coming from the aerea where the transmission meets the torque converter.
