2021 Ford Super Duty Chassis Cab 10 Speed Automatic Transmission

FORD TORQSHIFT® 10-SPEED AUTOMATIC TRANSMISSION

All Super Duty® Chassis Cab models now feature a standard Ford TorqShift® 10-speed automatic transmission, engineered to optimize drive ratios and improve shift performance. You can choose from five selectable modes — Normal, Slippery, Tow/Haul, Eco and Deep Sand/Snow — to match operating conditions. The Ford TorqShift 10-speed automatic transmission also offers Neutral Idle mode exclusively for Chassis Cab trucks. In Neutral Idle mode, the transmission automatically shifts into Neutral while stopped (if conditions allow it). It will then automatically resume shifting into Drive when you lift off the brake. This improves efficiency and reduces load on the engine, minimizing operating costs in the process.

LIVE-DRIVE PTO WITH MOBILE MODE

The available Live-Drive Power Takeoff (PTO) Provision with Mobile Mode* lets you power an aftermarket snowplow, pump, compressor or other accessory. The PTO provision is available across the entire engine lineup. An output gear connects directly to the engine crankshaft to power your PTO anytime the engine is running, whether the truck is in motion or stopped. Another big feature is "split-shaft" capability (diesel only) that allows multiple accessories to operate at the same time when the truck is stopped.

*Requires aftermarket power takeoff (PTO) accessory.

2021 Ford Super Duty Chassis Cab Engine Exhaust Braking Buttons

SMART DIESEL ENGINE EXHAUST BRAKING

The 6.7L Power Stroke® Turbo Diesel incorporates a smart exhaust brake function. When activated with a button on the instrument panel, the engine brake restricts the turbocharger's exhaust flow to generate back pressure and slow the vehicle. The main benefit is greater control while traveling downhill, regardless of vehicle load or road grade. Also, because the engine brake helps minimize having to apply pedal pressure, brake fade and lining wear are reduced, lowering the cost of maintenance. Three settings are available: On, Off and Auto. The Auto setting modulates engine braking as needed to help maintain the speed you want based on accelerator and brake pedal use.
