Possibly the wiring for the TCC solenoid inside the trans is chafed or pinched and is shorting. Very little clearance between the pan and the valve body and there are several wires and solenoids in there that can be damaged if something pushes against the pan.

 

I would unplug the large connector for the trans wire harness up by the firewall and check for corrosion there first. Then check the harness where it runs down the side of the trans for chafed wires. If that's clean the pan will probably need to be dropped to check the wiring inside the trans.
