2017 Honda CR-V Transmission & Axle Gear Ratios

Transmission gear ratios

The 2017 Honda CR-V was exclusively equipped with a Continuously Variable Transmission (CVT) across all trims. This CVT design offers a seamless and wide range of gear ratios, optimizing for both fuel efficiency and performance depending on driving conditions.

Available axle ratios

The 2017 Honda CR-V offered two primary axle ratios, largely dependent on whether the vehicle was equipped with two-wheel drive (2WD) or all-wheel drive (AWD).

Note: Honda typically does not use traditional RPO codes for axle ratios as seen in domestic manufacturers. The final drive ratio is inherent to the transmission and drivetrain configuration.

How to identify your axle ratio

Identifying the axle ratio on a 2017 Honda CR-V is not as straightforward as with some other manufacturers that use explicit RPO codes on door jamb stickers or axle tags. For the CR-V, the axle ratio is intrinsically linked to the vehicle's drivetrain configuration (2WD or AWD) and the specific CVT unit installed.

1. Drivetrain Configuration: The most reliable way to determine your axle ratio is to know if your CR-V is a 2WD or AWD model. This information is typically found on the vehicle's window sticker, title, or by checking the "AWD" badge on the rear of the vehicle for AWD models.
2. VIN Decoder: A Honda dealership or a reputable online VIN decoder service can provide detailed specifications for your specific vehicle, including the final drive ratio.
3. Owner's Manual/Service Manual: Your vehicle's owner's manual or a Honda service manual may also list the final drive ratios for different configurations.

Towing vs MPG impact

For the 2017 Honda CR-V, the final drive ratio of 5.64 is consistent across both 2WD and AWD models. However, the nature of the CVT (Continuously Variable Transmission) significantly influences the balance between towing capability and fuel economy.

• Fuel Economy: The CVT's primary advantage is its ability to constantly adjust the gear ratio to keep the engine operating in its most efficient RPM range. This results in excellent fuel economy for a vehicle of its class. The 5.64 final drive ratio, combined with the CVT's flexibility, allows for lower engine speeds at cruising, contributing to better MPG.
• Towing: While the 2017 CR-V has a modest towing capacity (typically up to 1,500 lbs), the CVT works to optimize power delivery for towing by adjusting to a "lower" effective gear ratio when more torque is needed. This helps the engine stay in its power band to pull a load more effectively. However, it's important to note that the CR-V is not designed for heavy-duty towing.

In essence, the CVT system is designed to provide the benefits of both numerically lower ratios (for MPG) and numerically higher ratios (for accelerating and towing) dynamically, on demand.

Common issues

While the 2017 Honda CR-V is generally a reliable vehicle, the CVT can be a point of concern for some owners. Specific to the drivetrain and ratios, some common considerations include:

• CVT Hesitation or Jerking: Some owners have reported issues with hesitation, shuddering, or jerking, particularly during acceleration or at lower speeds. This can sometimes be related to the CVT fluid condition or internal CVT component wear. Regular CVT fluid changes are crucial for longevity.
• Bearing Noise: While not directly related to the "axle ratio" itself, drivetrain components such as wheel bearings or differential bearings (in AWD models) can develop noise over time. A humming or grinding sound that changes with vehicle speed is a common symptom.
• AWD System Malfunctions (for AWD models): Issues with the rear differential or the AWD coupling unit can occur. This might manifest as clunking noises from the rear, especially during turns or when engaging AWD. Proper maintenance of the rear differential fluid is recommended.

It's important to note that these are generalized potential issues and not every 2017 CR-V will experience them. Regular maintenance as per Honda's recommendations is the best way to prevent such problems.
