Anyone have any ideas?

Hi my name is Erik and im having an issue with my
2003 chrysler T & C. It has 63K mi and its acting
like the torque converter is failing & it sometimes
shifts hard or erratic. The fluid is pink & free of
debris. There r no codes. I scanned it to check for
trans codes but it said there is no communication
with the transmission. Also once in a while the abs
light comes on but then the next day its off again,
this happens at least once a week. Any thoughts
as to what it could be? Thanks you for your time.
