2017 Cascadia. No crank, no start issue resolved. The transmission was the culprit, contrary to initial expectations. At McKain Diesel, we diagnosed the problem through code analysis, identifying a faulty shift control unit. We're replacing the rear main seal, clutch, shift control unit, and TCM on this DT12 transmission.
