Default 4l80e silenoid problem

I got a code for silenoid a stuck open. Before this code set for awhile it would shift fine at anything but wot and downshift fine. At wot it wants to downshift to I believe 1st even though pcm is commanding 2nd and if it's in 1st it won't shift to 2nd. Could this be from this silenoid going or would it be something else?

I'm just trying to see if I need a total rebuild or just replace this silenoid to fix my problems.
