The 4R55E has a higher torque rating than the 4R44E. There might be some internal differences. I'm only familiar with the differences on the A4LD which is used on the 3.0L compared to the 4.0L. They have a different bell housing, torque converter, rear snap ring, rear shaft, check ball configuration, and possibly other differences. I'm sure that the 4R44E has other minor differences compared to the 4R55E.
