That code is for a communication problem between NODES and must be tested with a scan tool by PINING all the nodes, and a lab scope to identify the signals. The NODES are all located in various parts of the car. it may or may not be covered under a warranty. There is no way for you to check tranny fluid level on that.

I guess your answer was the best you could do,however i don't feel that it was very helpful to the situation. I guess i must go to the dealer

The answer I gave you was 100% correct, and this is not a DIY job. It's unfair though that the expert gets held liable because the customer didn't like the answer.
