That was going to be my answer, too. But this diagram disagrees...



Notice the descriptions of 130 & 133 in its caption. That's from the service manual, but I've found MANY errors in the manual before.

PSOM calibration has a BIG impact on shift points in the E4OD & 4R70W because they're EEC/PCM-controled slushboxes. The axle sensor (RABS) is connected to the PSOM; not directly to the EEC.
