Good morning! I recently purchased a 2000 S70 GLT SE non-turbo with 148k miles on it. I want to do a major service on it because I dont know when the previous owner did any.

Transmission Filter/Fluid: What type of fluid does vehicle require? Some have told me this trans is not serviceable... any insight/tips?

Oil: What weight oil would be recommended for this vehicle considering mileage?

T-stat: What temperature rating is recommended?

Plugs: NGK are currently installed. What is recommended?

PCV: Is there one?

Brakes: Ceramic or semi metallic? Standard or drilled rotors?

ANy other service recommendations or tips are greatly appreciated!!
