Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

Did you check fault codes using a fully compatible scan tool that can plug into your model and can communicate with all computers in your vehicle?The reason I ask is some scan tools or code readers will only read the engine computer and you need the codes checked in all computers.Usually the flashing OD light and no shift issues are related and with the OD light flashing this indicates there is a code set for a transmission component at fault.This can be a shift solenoid failure which can be common.If your codes were checked with a fully compatible scan tool let me know.
