Hello all, I know that transmission fluid has been discussed, and have read most of the posts. I just wanted to get the opinion of the members here. I have about 6 liters of Volvo transmission fluid part number 1161640, not quite enough for a flush. So my question is, would you go to the dealer an pay 85.00 for a jug of Volvo fluid, or buy a 5 liter jug of Mobil 3309 and mix it with the Volvo fluid? The 5 liter jug of Mobil is 35.00. The transmission is a geartronic and the book recommends JWS 3309

 

I would go with the mobil 3309, or even
toyota type 4. I think its all the same fluid.

 

The Volvo fluid is Mobil1 JWS 3309. Mobil is the only manufacturer in North America. It's basically Dextron II fluid with extra anti-oxidizers and anti-foaming agents. It lasts a little longer than standard transmission fluid, especially in hot climates.

 

Are you just running around dragging up old posts to add what you think is correct?

It is not Dexron fluid. It is a quality specification. Educate yourself before posting all this crap please.
