Transmission jumps at different speeds.

Since I purchased my 2004 Toyota Highlander v6 it has very rough shifts. The transmissions seems to hesitate and lag when I try to accelerate during normal driving speeds, (I feel like I am on a carnival ride). I have had it to 3 different dealership in florida & they all say the same thing ("that this model drives like that" & it's the way you drive") funny though when the mechanic drove it, with me in the car he said that it was the transmission. The underwriters in service think because I'm a women, it's the way I drive. I love my car but, this problem needs to be addressed by Toyota & fixed !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!.
