The Ford Bronco Family showcases the Ford commitment to providing robust, capable transmissions engineered to handle everything from daily commuting to extreme off-road adventures. These sophisticated drivetrain components represent a perfect blend of durability, efficiency, and advanced technology, working in harmony with the Bronco’s powerful engines to deliver optimal performance across varied terrain and driving conditions.

10-Speed Automatic Transmission

The cornerstone of the Bronco transmission lineup is the advanced 10-speed automatic transmission, available across most trim levels. This sophisticated gearbox features a wide 7.39:1 gear ratio spread, providing exceptional low-end torque for off-road scenarios while maintaining efficient highway cruising. The transmission’s internal architecture incorporates six clutch packs and numerous planetary gear sets, enabling quick and precise shifts even under high-load conditions.

Ford engineers have implemented several refinements to enhance durability and shift quality. The transmission control module now features adaptive learning algorithms that continuously optimize shift timing and pressure based on the driver’s style and driving conditions. Internal components have enhanced materials in high-stress areas, including strengthened output shaft splines and redesigned valve bodies that improve hydraulic flow under extreme temperature conditions.

The cooling system features an enlarged transmission fluid cooler, which increases heat rejection capacity by approximately 15% compared to previous generations. This enhancement is particularly valuable during technical off-road maneuvers that can generate substantial heat within the transmission.

7-Speed Manual Transmission

The Bronco’s available 7-speed manual transmission continues to be a standout feature for enthusiasts who prefer complete control over their driving experience. This unique gearbox incorporates a dedicated ultra-low crawler gear (6.588:1 ratio) that provides exceptional torque multiplication for precise low-speed off-road maneuvers. When combined with the Bronco’s available 4.7:1 final drive ratio, this results in an impressive 94.75:1 crawl ratio—ideal for navigating challenging obstacles.

The manual transmission features triple-cone synchronizers on first and second gears, with double-cone synchronizers on third through sixth. This design reduces shift effort while enhancing durability during aggressive driving. The shift mechanism incorporates short-throw technology with precisely defined gates for positive engagement in all conditions.

The manual transmission receives an upgraded clutch system with a self-adjusting mechanism that maintains consistent pedal feel throughout the clutch’s service life. The dual-mass flywheel reduces driveline vibration while enhancing durability during high-torque applications.

Transfer Case Options

Both transmission options work in conjunction with one of two advanced transfer cases, depending on trim level and package selection. The base system features a two-speed electronic shift-on-the-fly design with 2H, 4H, and 4L modes, providing a 2.72:1 low-range ratio. Higher trim levels and specialized packages offer an advanced electromechanical transfer case with automatic on-demand engagement and a 3.06:1 low-range ratio for enhanced off-road capability.

The advanced transfer case incorporates a dedicated control unit that continuously monitors wheel speed, throttle position, and vehicle attitude to predictively engage four-wheel drive before slippage occurs. The system features enhanced sensors that can detect subtle changes in surface conditions, enabling a near-instantaneous response to traction loss.

Both transfer case options feature neutral towing capability, allowing the Bronco to be flat-towed behind recreational vehicles without accumulating distance on the odometer. This feature includes a specific control sequence to prevent accidental engagement while driving, enhancing safety and reliability.

Maintenance Considerations

Transmission maintenance requirements for the Bronco Family reduce service frequency while ensuring long-term reliability. The 10-speed automatic transmission utilizes MERCON® ULV (Ultra Low Viscosity) fluid specifically formulated for this application. Under normal driving conditions, this fluid should last the lifetime of the vehicle. However, severe service conditions—including frequent off-road use, heavy towing, or operation in extreme temperatures—may necessitate fluid changes at 96,000-kilometre intervals.

The 7-speed manual transmission requires periodic fluid changes using premium synthetic 75W-90 gear oil, with recommended intervals of 96,000 kilometres under normal conditions or 48,000 kilometres for severe service. The clutch hydraulic system utilizes DOT 4 brake fluid and should be flushed every 48,000 kilometres to prevent moisture accumulation and maintain proper pedal feel.

Transfer case maintenance follows similar guidelines, with fluid changes recommended every 96,000 kilometres under normal conditions or 48,000 kilometres for vehicles regularly used in challenging off-road environments. Both transfer case options use synthetic 75W-140 gear oil for optimal protection across a wide temperature range.

All Bronco models include enhanced transmission monitoring systems that analyze fluid temperature, shift quality, and clutch wear patterns to provide early warning of potential issues. This predictive maintenance capability works with the vehicle’s driver information center, alerting owners to service needs before performance is affected.

Integration with G.O.A.T. Modes: Terrain-Specific Calibration

The Bronco’s transmission systems are fully integrated with the G.O.A.T. (Goes Over Any Type of Terrain) mode selector, providing terrain-specific calibrations that optimize performance across varied driving conditions. In total, up to seven distinct modes are available depending on trim level and package selection.

Each G.O.A.T. mode applies specific transmission calibration parameters, including shift timing, torque converter lockup strategy, and shift firmness. In Baja mode, for example, the transmission maintains lower gears for longer periods and executes faster, firmer shifts to maximize performance during high-speed off-road driving. Conversely, Slippery mode initiates earlier upshifts and reduces torque during shifts to maintain stability on low-friction surfaces.

The transmission control module features enhanced mapping for each G.O.A.T. mode, with a particular focus on Rock Crawl and Mud/Ruts scenarios. These refinements provide more precise torque management during technical off-road maneuvers, enhancing vehicle control and reducing driveline stress.
