XC90 3.2 V8 Transmission Flush, Incremental, or Don’t Touch?
I just did mine on my 2008 3.2. It has the same trans as yours…the Aisin TF-80SC. At 64K, the fluid was dark as used engine oil…it needed it. It has no dipstick, so you need to be careful how you do it. I had a couple of S70′s and always did the fluid transfer/flush via the oil cooler line…so simple.
