Warning lights on dash with auto trans in limp mode.
Issue had been ongoing since panel repairs almost 2 years prior, and was initially intermittent, but now most of the time.
Initial diagnosis by dealership identified an internal transmission module fault, costing around $5,000 to fix.
Auto trans specialist suggested an electrical issue, based on the dash warnings displayed.

Reviewed previous diagnosis and all parties involved.
Confirmed ABS, Vehicle Dynamics Control, Hill Start Assist and the Engine MIL lamps illuminated in Instrument Panel Cluster.
