some do it bcs they are probably worried about how is oil and prefer do it sooner than later , is it necessary, I don't know...@FTO says that if you know you drive your raptor hard , perhaps you can think to do it sooner... I guess 100K miles is not bad for this maintenance operation!So again I ask though - Why are so many owners changing their fluids/fiter sooner? Is there a more recommended mileage period for this transmission?
