Some of the features of the Ford 6R140 transmission include:
- Six-speed automatic: The 6R140 has six speeds, allowing for smooth shifting and optimized fuel economy.
- TorqShift technology: The 6R140 features Ford's TorqShift technology, which includes a high-capacity pump and robust clutch packs for improved durability and performance.
- Tow/Haul mode: The 6R140 has a tow/haul mode that adjusts shift points for improved towing and hauling performance.
- SelectShift capability: The 6R140 can be shifted manually using the SelectShift feature, allowing the driver to manually shift gears when desired.
- Integrated PTO provision: The 6R140 has an integrated PTO (power take-off) provision, which allows for direct mounting of PTO units without requiring additional adapters.
Here are some additional details about the Ford 6R140 transmission:
- Applications: The 6R140 transmission is primarily used in Ford Super Duty trucks, including the F-250, F-350, F-450, and F-550.
- Construction: The 6R140 features a one-piece case design with integrated bellhousing, which helps to reduce noise, vibration, and harshness. It also has an aluminum alloy construction for reduced weight.
- Clutch packs: The 6R140 has multiple clutch packs that are optimized for high torque and heavy loads. The clutch packs are made of high-quality materials and are designed for durability.
- Shift quality: The 6R140 has smooth and precise shifts thanks to advanced control software and hardware. It also has a progressive range select feature that allows the driver to limit the transmission to a specific range of gears for improved control.
- Fuel economy: The 6R140 transmission is designed to optimize fuel economy while still providing high performance. It features a wide gear ratio spread, which allows for efficient operation at all speeds.
- Maintenance: The 6R140 requires regular maintenance, including fluid and filter changes, to ensure optimal performance and longevity. Ford recommends changing the transmission fluid and filter every 150,000 miles or every 5 years, whichever comes first.
6R140 Gear Ratios!
- Gear ratios: The 6R140 has six forward gears and one reverse gear. The gear ratios are:
- 1st gear: 3.97
- 2nd gear: 2.31
- 3rd gear: 1.51
- 4th gear: 1.14
- 5th gear: 0.87
