Allison Transmission recall: Power train
What is wrong
Allison Transmission, Inc. (ATI) is recalling certain Emergency Vehicle Series 6th Generation Transmission Control Modules (TCM). The transmission control module (TCM) may fail to achieve the 4th gear transmission lockup needed to initiate the water pump.
What could happen
Failure to achieve 4th gear lock up may prevent the vehicle from achieving the full sequence needed to pump water, which can increase the risk of injury in an emergency.
The fix
Vehicle manufacturers will update the TCM software, free of charge. ATI notified the affected vehicle manufacturers on July 31, 2023. Owners may contact ATI customer service at 1-317-242-5000.
