    when is the 3-2 shift solenoid supposed to be active/on?

    i have a freshly rebuilt "built" 4l65e that shifts great in all gears except 4th gear/overdrive,it wont even try to engage 4th when commanding it manually through hpt..anyway,i did some logging trying to figure out this no 4th gear issue and I noticed the 3-2 shift solenoid turns on around 40mph and stays on until I slow down to around 25mph,if I speed back up it turns back on and so on,my question is..is this normal operation of the 3-2 downshift solenoid? or could it have something to do with my no overdrive issue? I attached the last log I did,tia.
