The ecu was programmed to have more power and a delete of egr system, and this truck will be private use only no D.O.T #. Anyways after the programming my check transmission light its now on. Im unsure of what to do I think it has something to do with the programming causing the check trans light on.

Had programmed computer (deleted egr), also got more power through programming. but now my check trans is on after reinstalling the brain. Any ideas check trans was never ion till egr/boost of power was installed
