2001 S60 2.4T
 

After using the search feature on this forum and reading all 12 pages about S60 automatic Transmissions I learned alot of valuable information. I have a 2001 S60 2.4tw/ 163000 miles on it. I have been told the fluid is dark by Volvo as well as my mechanic. Nothing was mentioned about a burnt smell, or any upgrade. I am confused about the fluid to use Mobil 3309 or Volvo brand. Also I have had no problems but I have no idea about whether or not the fluid has been changed on recommended intervals or ever.The car seems to accelerate and change gears just fine. I would like a little further information about something i read in one of the posts about what happens when the car is at a stop going into neutral. I have not noticed this. I have been told not to mess with it by my mechanic because it will just stir up the gunk and maybe cause problems. Should I do as they say "don't fix it if it isn't broke" or do you recommend a flush and fill or a drain and fill. Last but not least. What is the part number for the 2001 S60 2.4t tranny if I should ever need one? Is it a Aisin-Warner. Thanks everyone. Fred

On my 91745t, the trans was never flushed until a few months ago.
It went 238,000miles and then we finaly got around to doing it:D.
I used royal Purple trans fluid..it works very well.
Go ahead and flush it.
You should have an AW 55- 50 trans.
Good luck.
