Since your diagnostic light has come on with this issue here now the first thing that should be done is to have the fault codes read out/checked with a scan tool or dealers sds machine to see what codes are set.Once this has been done any codes set will need diagnosed to locate and repair this fault here.
From what is described this sounds like a fault with the valve body itself in the transmission possibly or an issue with a sensor or solenoid on the valve body.In some cases I have seen issues with the transmission fluid pump or even a bigger issue internally in the transmission with it needing removed and inspected then repaired.
I would start with having the fault codes checked to see what codes are set then from there those codes diagnosed and repaired.I suspect one of these above are the cause here that will need repaired.
