On my 2002 4.4 with 125k I had the trans oil changed and filter changed.

OEM fluid and filter. The old fluid was black.

I now have harsh downshift...also if I tap the gas it slightly bangs....none of this is extreme but now its there and it wasn't before the oil change.

I was wondering if anyone else had this problem. Any ideas maybe add something to the oil?

Thanks
