Car: 2002 Chevy Venture mileage 63,000kms

Was reading the manual. Walang sinabi kung kelan papalitan ang brake fluid, power steering fluid at fuel filter. My question is, when should these be replaced. Also, the manual says to replace ATF at 83,000kms. Hindi ba ang tagal nito? I called the casa and they said at 40,000km. Is this correct or are they just trying to make money? Mukhang clear pa naman yung brake fluid. Yung ATF ay hindi naman amoy sunog.

Hindi ko alam kung napalitan na. Ano ang advise niyo, palitan na o ok lang?
