2022 Ford Ranger Transmission & Axle Gear Ratios

Transmission gear ratios

The 2022 Ford Ranger comes exclusively with one transmission option, the 10-speed automatic, known as the 10R80.

Available axle ratios

The 2022 Ford Ranger offers a few axle ratio options, depending on the drivetrain and package. These ratios significantly impact the truck's performance characteristics, including towing capability and fuel efficiency.

How to identify your axle ratio

Identifying your 2022 Ford Ranger's axle ratio is crucial for proper maintenance, upgrades, or when researching towing capacities. The simplest way to find this information is by checking the door-jamb sticker, specifically the “AXLE” code. While not a direct ratio, this code corresponds to a specific axle configuration and ratio. For example, "86" typically indicates a 3.73 non-limited-slip differential, while "87" signifies a 3.73 electronic-locking differential. The "88" code is for the 4.27 electronic-locking differential found in the Tremor package.

Always double-check your owner's manual or a Ford VIN decoder for the most accurate information if you're unsure.

Towing vs MPG impact

The axle ratio plays a direct role in striking a balance between towing performance and fuel economy. Generally, a numerically lower axle ratio (e.g., 3.73) means the engine operates at lower RPMs at a given road speed. This results in better fuel efficiency, as the engine doesn't have to work as hard to maintain cruising speeds. However, it also means less mechanical advantage for accelerating from a stop and pulling heavy loads.

Conversely, a numerically higher axle ratio (e.g., 4.27) allows the engine to spin at higher RPMs. While this will decrease fuel economy, it provides a significant advantage for towing heavy trailers or navigating challenging off-road terrain. The higher ratio offers more torque to the wheels, making it easier to get a load moving and climb steep inclines.

For the 2022 Ford Ranger:

• 3.73 Ratio (Standard): Offers a good balance for daily driving and occasional towing. It provides decent fuel economy while still being capable enough for moderate loads.
• 4.27 Ratio (Tremor Off-Road Package): Specifically designed for enhanced off-road performance and heavier towing. While it provides superior pulling power, expect a slight decrease in fuel efficiency compared to the 3.73 ratio.

Common issues

While the 2022 Ford Ranger's drivetrain components are generally robust, some common issues can arise with differential and axle components over time, similar to other vehicles:

• Ring & Pinion Whine: A distinct howling or whining noise, especially at certain speeds or under acceleration/deceleration, often indicates wear in the ring and pinion gears. This can be caused by improper setup, lack of lubrication, or heavy use.
• Carrier Bearing Wear: The bearings supporting the differential carrier can wear out, leading to growling noises, vibrations, or even clunking sounds, especially during turns or when shifting from drive to reverse.
• Limited-Slip Clutch Wear (if equipped): Rangers with a limited-slip or electronic-locking differential (like the 4.27 in the Tremor) rely on clutch packs or electronic solenoids. Over time, these components can wear, leading to reduced effectiveness of the locking mechanism or chatter during tight turns (for limited-slip differentials).

Regular differential fluid changes with the correct type of fluid are crucial for extending the life of these components and mitigating these common issues.
