2017 Ford Escape: Transmission & Axle Gear Ratios

Transmission Gear Ratios

The 2017 Ford Escape comes equipped with a six-speed SelectShift automatic transmission, designated as the 6F35. This transmission is paired with all three available engines.

Available Axle Ratios

Unlike body-on-frame trucks and SUVs, the 2017 Ford Escape is a crossover with a transaxle-based all-wheel-drive (AWD) system. It doesn't have a traditional solid rear axle with a separate differential. Instead, it has a single final drive ratio integrated into the transaxle, with a rear power transfer unit (PTU) for AWD models that matches this ratio.

For 2017, the Escape was offered with one primary final drive ratio across all engine and drivetrain configurations to optimize the balance between performance and fuel economy.

How to Identify Your Axle Ratio

Since the 2017 Escape doesn't have multiple axle options, there isn't a need to "decode" your ratio. However, you can confirm your vehicle's build specifications in a few ways:

• Safety Certification Sticker: Ford vehicles have a sticker on the driver's side door jamb. While it won't show different axle options for the Escape, the "AXLE" or "TR" code can be used by a dealer to confirm the original equipment.
• VIN Decoder: A VIN decoder can provide a detailed build sheet for your specific vehicle, listing the final drive ratio along with other standard and optional equipment.
• Owner's Manual: The owner's manual often contains detailed specifications for the vehicle's powertrain, including the final drive ratio.

Towing vs. MPG Impact

While the Escape isn't offered with multiple axle ratios to choose from, it's still helpful to understand the principle. The 3.51 final drive ratio was chosen by Ford's engineers as the optimal compromise for the platform.

• Towing: The 2017 Escape has a maximum towing capacity of up to 3,500 pounds when properly equipped with the 2.0L EcoBoost engine and the Class II Trailer Tow Package. This rating is achieved thanks to the engine's power and the gearing of the 6F35 transmission, particularly its aggressive 4.584:1 first gear, which helps get a load moving.
• Fuel Economy: The 0.746:1 overdrive sixth gear allows the engine to operate at a lower RPM during highway cruising, which is key to maximizing fuel economy. The 3.51 final drive ratio provides a good balance, enabling brisk acceleration without keeping engine revs too high on the freeway.

Common Issues

The 6F35 transmission in the 2017 Escape is generally reliable, but some issues have been reported. It's important to note that not all vehicles will experience these problems.

• Harsh or Delayed Shifting: Some owners have reported occasional harsh shifts, particularly between 2nd and 3rd gear, or a delay when shifting into Drive or Reverse. This can sometimes be attributed to software that needs an update, but it can also indicate internal component wear or fluid issues.
• Torque Converter Problems: In some cases, a failing torque converter can cause a shudder or vibration, especially under light acceleration at speeds between 25-50 mph. This is a known issue on some Ford models equipped with this transmission family.
• PTU (Power Transfer Unit) Leaks/Failure: On AWD models, the PTU directs power to the rear wheels. These units can sometimes develop fluid leaks from their seals. In more extreme cases, overheating due to fluid loss or high mileage can lead to internal gear or bearing failure, which may present as a whining or grinding noise from the front-center of the vehicle.

Regular maintenance, including changing the transmission fluid according to the schedule in your owner's manual, is the best way to ensure the longevity of your transmission and driveline components.
