Manual Transmissions Heavy-Duty/Medium-Duty Transmissions totally submerged in water: Replace complete transmission. Inspect shift tower/lever assembly for rust damage and replace damaged components as needed. Inspect vehicle air supply system for water intrusion and repair as needed. Transmissions partially submerged in water: Completely drain transmission lube. Remove PTO covers from transmission main case and visually inspect internal components for rust: o If rust is found on internal components, remove the transmission from the vehicle and replace damaged components as needed.

2 O If no rust of internal components is found, flush per Service Bulletin TMIB0124 and refill transmission with approved lubricant. Inspect transmission air system for water intrusion and replace damaged components as needed. Inspect vehicle air supply system for water intrusion and repair as needed. Automated Transmissions - Heavy-Duty/Medium-Duty Automated Transmissions totally submerged in water: Replace complete transmission, including transmission mounted electronic components (TECU, HCM, transmission harness, XY Shifter, ECA, Inertia Brake, Range/Splitter Valves, Speed Sensors). Inspect transmission vehicle interface harnesses for water intrusion or corrosion and repair/replace damaged harnesses as needed. Inspect vehicle air supply system for water intrusion and repair as needed.
