Transmission Not Shifting?

Recently went to pull one of my friends out of the mud with my ford f150, i got stuck, had water an inch from coming in through my doors (water was touching the rockers). Left the truck over night, got pulled out by a full size loader. The truck refuses to shift into any gear higher than first, it makes the attempt to shift at about 6500 rpms and then slams the truck forward but remains in first. At about 3000 rpms the truck shifts out of any gear and will regain movement again at 3000 rpms. I checked the dipstick there are little bubbles on it im guessing i got water in through the breather tube...One of my friends mentioned the solenoids but I don't know. Any USEFULL help would be appreciated (No saying "your problem is the blue oval on the grille"). I am going to flush the transmission but I doubt it will help. Thanks!
