Make sure the connector is tight.
When you had the pan off these solenoid wires are exposed, could you have disturbed them?
Sorry for the late reply, turns out the guy I hired to do the transmission oil change decided to put oil through a hole where a bolt goes because he thought there was no dip stick for the transmission. It ended up throwing some things around in the transmission so I had to get the transmission knocked down to be fixed. Plus he lost the modulator pin so I went through hell trying to find another one!
