in my xf witch is an auto
every time i go from a complete stop and accelerate, unless i completely granny the accelerator.. theyres a grinding noise, sorta like if you were to put something in some fan blades... this doesnt stop till youve picked a decent amount of speed up
also, when changing gears, ie. from park to reverse, its not very smooth.. seems to jump
the transmission fluid is full, no grinding noise is heard when reving it in neutral, etc.
anyone got anyidea?
