Hi
My 2.7 XF (2008) has developed what I can best describe as a shudder when accelerating, particularly up an incline but not necessarily, if I back off a little or press the throttle it goes away.
I have had suggestions of low ATF or poor quality ATF.
It does not sound like the typical quick “grrr” sound of a slipping torque converter clutch glazing symptom, more like a clutch shudder on a stick shift.
Anyone come across this or have any wise insight?
