I am not an expert on these matters and what I say is given in good faith and to the best of my lateral thinking skills. This may get difficult, but here goes anyway.
I think this means the Transmission ECU has lost its power from the battery – some sort of connectivity problem – and it can’t “talk”. This would be my first assumption at solving this because it is the easiest – always do the easy things first with system diagnosis.
• Firstly disconnect the battery and clean the posts and clamps and reconnect. Does it solve the problem?
• Secondly check the fuse that relates to the Transmission ECU is OK. Does it solve the problem?
• Thirdly find the transmission ECU and remove and clean the plug/socket and reconnect. Does it solve the problem?
Let us know how it goes after all that.
