Ok so I just text my Subaru mechanic again. I asked him if there’s further scans he can run aside from the one he did on that laptop and aside from him doing a relearn of the transmission. Btw he is doing this on the side for me and didn’t charge for the re learn or the original quick diagnostic. There are no codes like I’ve mentioned just a steady yellow “AT Oil Temp” light.Temperature sensors are on the valve body. So far if the temperature sensors are bad on the valve body the valve body gets replaced. If there is an issue with fluid flow that's preventing the proper temperature regulation of the fluid then you have to find out what that is.
Look up p0712 and p0713.
