I just did one of these the other day, I removed the transmission pan and found a screw on filter had backed itself off. Good luck, transmissions are hard to fix this should keep you busy for a while that may know if you need more information

Inspect the wires make sure you check the screw on filter make sure it is not lose, give it a general inspection and double check your work.
