Cannot manually shift into higher gears (10th and above) on a 2023 Cascadia DD15 with DT12 transmission using Detroit Diagnostic Link (DDL); the transmission reverts to economy mode and displays an error.
DDL software lacks clear guidance or a feature to override transmission control for manual shifting in higher gears on this specific truck model.
