2020 Honda Pilot Transmission & Axle Gear Ratios

The 2020 Honda Pilot is a highly capable and versatile three-row midsize SUV. Under the hood, all 2020 Pilot models are powered by a robust 3.5-liter V6 engine producing 280 horsepower. However, how that power makes its way to the pavement depends entirely on the transmission and axle gearing equipped in your specific trim level.

Understanding your Honda Pilot's gear ratios is crucial if you are planning to tow a heavy trailer, looking to optimize your highway fuel economy, or needing to replace driveline components. Below is a comprehensive breakdown of the transmission and axle gear ratios for the 2020 Honda Pilot.

Transmission gear ratios

For the 2020 model year, Honda offered two different automatic transmissions for the Pilot, depending on the trim level. The LX, EX, and EX-L trims come standard with a 6-speed automatic transmission. Stepping up to the Touring, Elite, or Black Edition trims swaps the 6-speed for a more advanced 9-speed automatic transmission (supplied by ZF), which provides a wider gear spread for improved acceleration and highway cruising efficiency.

9-Speed Automatic Transmission (Touring, Elite, Black Edition)

Available axle ratios

Unlike pickup trucks that offer a wide menu of rear axle ratios (like 3.31, 3.55, 3.73, or 4.10), the 2020 Honda Pilot utilizes a transverse-engine architecture with an integrated transaxle. The "axle ratio" in this context is the Final Drive Ratio. The final drive ratio is strictly tied to which transmission your Pilot is equipped with. Both front-wheel drive (FWD) and all-wheel drive (AWD / i-VTM4) models use these same final drive ratios.

Note: All AWD models feature Honda's i-VTM4 (Intelligent Variable Torque Management) rear differential unit, which actively vectors torque between the left and right rear wheels.

How to identify your axle ratio

Because the 2020 Honda Pilot does not have optional axle ratios within the same trim level, identifying your final drive ratio is straightforward once you know your trim and transmission. However, if you are purchasing a used model or replacement parts, you can verify your driveline setup using these methods:

• Door-Jamb Sticker: Open the driver’s side front door and locate the vehicle certification label (often called the RPO sticker on GM vehicles, but Honda uses a standard certification label). While it won't explicitly list "4.25" or "4.33," it will display the exact trim level and transmission code.
• Transmission Tag: The transmission itself has a stamped barcode and alphanumeric tag on the bell housing or upper casing. This barcode can be cross-referenced with Honda service manuals to determine the exact transaxle and final drive assembly.
• VIN Decoder: The easiest and most accurate way to verify your final drive ratio is to run your 17-digit Vehicle Identification Number (VIN) through a Honda VIN decoder or provide it to a Honda parts dealership. The VIN dictates exactly which transmission (and thereby final drive ratio) the vehicle was built with at the factory.

Towing vs MPG impact

Gear ratios play a massive role in balancing a vehicle's towing capabilities against its fuel economy.

Numerically lower ratios (e.g., lower final drive gearing overall): Generally, lower numerical ratios mean the engine turns at a lower RPM at highway speeds. This results in better fuel economy and a quieter cabin, but it reduces the mechanical torque multiplier at the wheels, making it harder to tow heavy loads up steep grades.

Numerically higher ratios (e.g., 4.334): A higher numerical final drive ratio acts as a larger torque multiplier. It helps get heavy loads moving from a dead stop and assists in maintaining speed up hills. The 9-speed Pilot uses a higher 4.334 final drive ratio compared to the 6-speed's 4.250. You might think this hurts MPG, but because the 9-speed transmission has multiple deep overdrive gears (7th, 8th, and 9th), the Pilot can still achieve excellent highway fuel economy while offering superior off-the-line torque for towing.

When equipped with AWD and an ATF cooler, the 2020 Pilot is rated to tow up to 5,000 pounds, regardless of which transmission/final drive combo it has. FWD models are capped at 3,500 pounds.

Common issues

While the 2020 Honda Pilot's driveline is generally reliable, there are a few things owners should keep an eye out for as the mileage increases:

• 9-Speed Shifting Quirks: The ZF 9-speed transmission is known for occasional hard shifts or hesitation, particularly between the 2nd and 3rd gears, or when downshifting under heavy throttle. Software updates from Honda have largely addressed this, but it remains a common complaint.
• i-VTM4 Rear Differential Fluid: The rear differential on AWD models is highly sensitive to fluid degradation. If the dual-pump fluid breaks down, you may experience a humming noise, clutch wear, or a juddering sensation when turning at low speeds. Honda recommends changing the rear differential fluid (VTM-4 / DPSF) every 15,000 to 30,000 miles depending on driving conditions.
• Torque Converter Shudder: On higher-mileage 6-speed models, some owners report a mild shudder or vibration at cruising speeds (35-45 mph). This is typically related to the torque converter lock-up clutch and can often be remedied by a triple flush of the transmission fluid.
