I’ve searched the web, and I’m coming up empty.
Has anyone done a drain/fill on a late model 8 speed tranny in a Volvo? I’m thinking there has to be a fill plug somewhere where I can use a Mityvac to suck out and replace some fluid? Volvo says it’s a lifetime fluid. I did find the spec for the fluid is AW-1. Searching around, I don’t even see many readily available AW-1 fluids.
I am not certain about the 8 speed, but on the 6 speed TF-80 SC Aisin in my Volvo, the fill plug is on top of the transmission under the air filter, but you cannot suction the fluid out because the gears get in the way when trying to fish the tube down into the fluid. The fill plug is a large Torx plug
