What could be causing these electrical issues.

It is a 4l60E. Do you think its possible that the solenoid could have stuck or something when the switch went bad and it wasn't getting power? I have power at the ign o in the fuse box, thats the first place it goes when ignition turns on. I haven't checked any where else yet.

It looks like it's pointing to the solenoid. The knock sensor code is gone. I have been looking online and am not sure which solenoid is which. Are the 1-2 and the 3-4 solenoid the same thing in a different slot in the trans.I found a pic but that doesn't help much. Do you have a diagram of location and part number.

Just wanted to let you know. I replaced both solenoids and filter while doing it. Truck shifts fine. Its just weird that broke at the same time all the trans codes and battery drain caused by the ignition switch. BTW, do you guys have jeep mechanics. My daughter is having issues with her her 2001 grand cherokee?
