P0702 and blown ABS fuse

[DLGonzo]

Was pulling a small trailer when abs and traction lights come on along with check engine. Goes into limp mode. All I can find is a blown abs fuse and blows every other fuse I put in when ignition on. Unplugged trailer, abs module and front wheel speed sensors and still blow the fuse. P0702 with code reader. I assume there’s a short somewhere but haven’t found anything. Any other thoughts?

Specifically which fuse? There are 4 that could be associated.
P0702 is a transmission code.

Looks like it’s the F77 DTCM FUSE. either my old eyes are failing me or I can’t read the convoluted fuse map. That would make sense with the code
