2025 Chevrolet Equinox Transmission & Axle Gear Ratios

Transmission gear ratios

The 2025 Chevrolet Equinox is expected to continue offering a continuously variable transmission (CVT) for its standard front-wheel-drive (FWD) models, and potentially an automatic transmission for all-wheel-drive (AWD) variants, though specifics are not yet confirmed for the 2025 model year. Based on previous generations and industry trends, a 9-speed automatic transmission is a likely candidate for AWD.

CVT (Continuously Variable Transmission)

CVTs do not have fixed "gears" in the traditional sense but operate with a continuously changing ratio. For comparison purposes, manufacturers often provide a range of effective ratios.

Available axle ratios

Axle ratios for the 2025 Chevrolet Equinox are typically optimized for a balance of fuel economy and performance, given its classification as a compact SUV. Specific ratios can vary based on the powertrain (FWD vs. AWD) and trim level.

Note: These are estimates based on previous model years and common Chevrolet compact SUV specifications. Official 2025 specifications should be verified upon release.

How to identify your axle ratio

For Chevrolet vehicles, the easiest way to identify your axle ratio is by checking the RPO (Regular Production Option) sticker. This sticker is typically found in the glove compartment, on the driver's side door jamb, or under the rear cargo floor mat.

Look for a three-digit code starting with "GU" for your axle ratio. For example, "GU4" typically denotes a 3.08 ratio, while "GM7" might indicate a 3.42 ratio. If you cannot locate the RPO sticker or find it illegible, a Chevrolet dealership can provide this information using your VIN.

Towing vs MPG impact

The axle ratio plays a significant role in the balance between towing capability and fuel efficiency.

• Higher (numerically larger) axle ratio: A numerically higher axle ratio (e.g., 3.47:1) means the engine performs more revolutions for every revolution of the wheels. This provides greater torque multiplication at the wheels, resulting in improved acceleration and enhanced towing capacity. However, the trade-off is often reduced fuel economy, as the engine runs at higher RPMs at any given speed.

• Lower (numerically smaller) axle ratio: Conversely, a numerically lower axle ratio (e.g., 3.17:1) means fewer engine revolutions per wheel revolution. This allows the engine to operate at lower RPMs at cruising speeds, contributing to better fuel efficiency. The compromise is generally a slight reduction in off-the-line acceleration and maximum towing capability.

For the 2025 Equinox, the available ratios are designed to cater to slightly different priorities. The lower ratio (e.g., 3.17) is typically paired with FWD models, prioritizing fuel economy for everyday commuting. The higher ratio (e.g., 3.47) often accompanies AWD models, offering a better balance for those who might occasionally tow light loads or desire slightly more responsive acceleration.

Common issues

The Chevrolet Equinox, as a popular compact SUV, is generally reliable. However, like any vehicle, certain driveline components can experience wear over time.

• Ring & Pinion Whine: A common symptom of worn or improperly set-up differential gears is a whining noise that changes with vehicle speed and load. This can indicate excessive backlash or worn gear teeth.

• Carrier Bearing Wear: The carrier bearings support the differential
