Hi, my question is where can I find the P0715 Input/Turbine Speed Sensor Circuit on 2002 BMW 530i

I was driving through a tough rain and the water was flooding the street very fast, I was able to make it home but my car now has the transmission stuck in a high gear. I ran the code diagnostic and this is the one that came out, P0715 Input/Turbine Speed Sensor Circuit Malfunction. Just wanted to know if its a job a could so myself, I'm not a certified mechanic but I usually do most jobs in my car.

I just had this same issue after a carwash that included the undercarriage spray. When I got home I disconnected the large plug at the back of the transmission to find it was full of water. I blew out the connections with compressed air and BAM! that fixed it.
