Code P083B it's Telling me Transmission Fluid position Sensor G Circuit

What is your question?

Pulled to my drive way my 2015 Chrysler Town and Country top right there and then it shifted again with a bang so I finally parked it and I start it and I can go back and fourth with it no problem but it starts when it warms up were is this sensor location on my Tranny. Like said this is the code that came up P083B

What makes this problem better or worse?

When it heats up

How long has your 2015 Chrysler Town & Country had this problem?

One week I won't Drive it at all until problem is fix
