You can run the amsoil for you aod.Just call them and ask what they think.It should shift smoother and you will not have to change every 30,000 like you are supposed to but its nice to.The only way to totaly flush the trany clean is to go to penzoil quick lube or the like and pay like 80 bucs for a trany fluid change.They use a cool machine that hooks to your two trany lines and you run the car and it replaces fresh fuid and removes the return dirty til it get to be clean fuid coming out the trany line.The only thing is they don't change the trany filter just flush it.
