2017 Toyota RAV4 Transmission & Axle Gear Ratios

The 2017 Toyota RAV4 is a staple in the compact crossover segment, renowned for its reliability, practicality, and efficiency. Whether you are replacing a transmission, diagnosing a driveline vibration, or just curious about how your RAV4 puts power to the ground, understanding its gear ratios is essential.

For the 2017 model year, the RAV4 was offered with two distinct powertrains: a traditional 2.5L 4-cylinder gas engine paired with a 6-speed automatic, and a 2.5L hybrid powertrain utilizing an electronically controlled Continuously Variable Transmission (eCVT).

Below is a comprehensive guide to the transmission and axle ratios for the 2017 Toyota RAV4.

Transmission gear ratios

The standard gas-powered 2017 RAV4 utilizes the U760E (FWD) or U760F (AWD) 6-speed automatic transmission. This gearbox is designed for smooth shifts and a balance of low-end torque and highway fuel economy.

The RAV4 Hybrid uses the P314 eCVT, which uses planetary gearsets and electric motors rather than traditional stepped gears, providing infinite ratios between its lowest and highest limits.

6-Speed Automatic (U760E / U760F)

Standard on all 2.5L Gas Models (LE, XLE, SE, Limited, Platinum)

eCVT (P314)

Standard on 2.5L Hybrid Models (XLE, SE, Limited)

Available axle ratios

Unlike heavy-duty trucks that offer a wide menu of axle ratios for specific towing needs, the Toyota RAV4’s final drive (axle) ratios are intrinsically tied to the powertrain selected.

The gas models use a standard mechanical final drive, while the Hybrid utilizes a front transaxle final drive and an independent rear electric motor (MGR) for AWD, meaning the rear wheels are not mechanically linked to the transmission.

Note: The hybrid's rear axle ratio represents the reduction gear for the rear electric motor, which operates independently of the front wheels.

How to identify your axle ratio

While domestic trucks often use RPO stickers (like GM's glovebox sticker) or axle tags (like Ford/Ram), Toyota uses a specific data plate located in the driver’s side door jamb. Here is how to decode it:

1. Locate the Certification Label: Open the driver's side door and look for a black or white sticker on the door pillar (B-pillar).
2. Find the A/TM Code: Look near the bottom of the label for a line starting with "C/TR" (Color/Trim) and "A/TM" (Axle/Transmission).
3. Decode the Axle: The first part of the A/TM code (e.g., -01A) indicates the axle code. For a 2017 RAV4, this almost universally corresponds to the 3.815 final drive ratio on gas models.
4. Use a VIN Decoder: If the sticker is faded or missing, running your RAV4’s Vehicle Identification Number (VIN) through a Toyota VIN decoder or providing it to a local dealership parts department will confirm your exact drivetrain specifications.

Towing vs MPG impact

Understanding the impact of your axle ratio (final drive) helps explain how your vehicle performs under load versus cruising on the highway.

• Numerically Lower Ratios (e.g., 3.542 on Hybrid): These are often referred to as "tall" gears. A lower numerical ratio keeps the engine RPM lower at highway speeds, which significantly improves fuel economy and reduces cabin noise. However, it provides less mechanical torque multiplication for rapid acceleration or towing.
• Numerically Higher Ratios (e.g., 3.815 on Gas models): Often called "short" gears. A higher numerical ratio means the engine turns more times for every rotation of the tires. This increases wheel torque, providing better acceleration off the line and making it easier to tow. The 2017 gas RAV4 has a modest 1,500 lb towing capacity (3,500 lbs for the Adventure trim which debuted slightly later with an upgraded cooler), supported by this 3.815 ratio. The trade-off is slightly lower highway MPG.

Common issues

The 2017 Toyota RAV4 is highly regarded for its drivetrain reliability, but as mileage accumulates, there are a few things to watch for:

• U760 Automatic Transmission Shudder: Some gas models may develop a slight shudder between 2nd and 4th gears. This is often related to aging transmission fluid or torque converter lock-up wear. Fluid changes every 60,000 miles (even though Toyota calls it "lifetime" fluid) are highly recommended.
• AWD Transfer Case/Viscous Coupling Whine: On gas AWD models, the electromagnetic coupling that sends power to the rear wheels can sometimes develop a hum or whine if the differential fluid is neglected. If you hear a high-pitched noise from the rear on acceleration, check the differential fluid.
• Carrier Bearing Wear: High-mileage AWD RAV4s may experience wear in the driveshaft carrier bearing, resulting in a thumping noise or vibration directly under the center console at moderate speeds.
