I am sorry that you have not been helped yet. I just came online and saw your question
P1784 = Low / Reverse pressure switch circuit.
What it means is there is a problem with circuit going to one of the pressure switches in the transmission, or an internal transmission problem. The controller is turning on the low reverse clutch, but it's not seeing it's pressure switch close.
Generally it indicates a problem with the transmission solenoid pack (it contains all the actuators and pressure switches for the transmission) but it can also indicate an internal transmission problem. Diagnostics can be a bit tricky without a true scan tool and a transmission pressure gauge
