Changed the transmission fluid and there is a lot of difference - smoother gear change, better response ratio, and correct color! I will not buy any thing but this stuff.

Good Stuff. Drain and fill Volvo 850

Smooths Out Transmissions

I did a 'drain and fill' (not a flush) on our 2004 Volvo XC70 with 190,000 miles and the Redline ATF really smoothed out the transmission. Note that I have been doing transmission changes on this car since 90,000 miles. If you have over 100,000 on your Volvo and you have never changed the transmission fluid, I would highly recommend having a talk with your mechanic before you do so.
