i have volvo S60 T5 97000 km

How often recommended by the manufacturer to replace Transmission Fluid

i had problem with valve body

please i need yours help .........

 

I am not sure you will get VOLVO to say that it ever should be chaged but i am looking to do mine Trany fluid and my car had 85,000 and just about everyone i have talk to say "YES DO IT FOR SURE" Even Local Volvo dealer.The one big difference is that Volvo only emptys fluid in the pan and replaces it thats maybe 1/4 of the fluid in system.I am going to flush useing IPD little kit and fluid until i get red fluid to come out.Volvo is a car if its treated right you cant go wrong.
