I have a 2005 S60 T5 turbo with automatic transmission, I would like to drain transmission fluid and replace with mobil 3309. Were do you fill the transmission I cannot find the dip stick or any other way to fill transmission.

 

 

I removed the intake to service the PCV system and I found the dip stick down under the turbo hose to the intercooler. 2005 turbos may be different not sure how you would find the dip stick without removing the intake.

By the way I am changing the timing belt with 105,000 miles belt looks great no cracks, tensioner looks good. Timing belt change on the volvo is a very easy job once you find the small slaches on the cam sprockets.
