Transmission is in limp mode and checking for power.
Is there a relay for the transmission on the vehicle listed above it is the 2500 and if so where is it located?

The vehicle has a transmission control module. I believe it is under hood near the power distribution center. Before dealing with that, check for trouble codes. The OBD 1 system should point you in the right direction.
