Wifes 2006 XC90 2.5T is having some shifting issues. Car has 130K on it, and fluid was just flushed with Mobil 3309 fluid. Flushed by pulling the line and flushing 2 qts at a time. Last flush was at 90K.
Getting some torque converter chatter under load at low RPMS. Mostly at 40-50 MPH.
From what I can find next step could be a software update and/or a transmission adaptive reset? Any advice as I proceed? I have the Vida/Dice unit that I just purchased. Is a greenboard chinese unit.
Is there a procedure listed somewhere for this? Or am I better off taking it to the Dealership and letting them do this?
