Order of inspection
P0945 Hydraulic Pump Relay Circuit Open High
The P0945 code means the control circuit of the hydraulic pump relay is open, so the component gets no current when the computer commands it. That can lead to a loss of hydraulic pressure and a gearbox that stops shifting. Check the fuse, the relay, the connector and the wiring before replacing anything.
