code p1781 2001 2500 HD Silverado, Duramax, Allison

First time posting, hope someone can help me.
My service engine light came on, went to Autozone for their free check.
P1781 is the code, poor or lost communication with TCM ( transmission control module ?? )
Any suggestions?
Thanks in advance for any help, I hate to take it to the dealer.
