Is there any transmission filter and where is it located in the Volvo S60?

What is your question?

The car is sluggish in tacking off. I have to rev it before it begins to crawl but once moving it drives normal. The dashboard sometime flashes a message sing "Transmission services required". I am trying to replace the filter but I can't seem to find it. I see the pan but where is the filter located? Please help or send me a site or video that can help. Thanks

What makes this problem better or worse?

Nothing in particular. It comes and goes
