2015 Toyota RAV4 — Transmission & Axle Gear Ratios

Transmission gear ratios

Applies to North American 2015 Toyota RAV4 (LE, XLE, Limited) with the 2.5L 2AR‑FE engine. The RAV4 used Toyota’s U760 6‑speed automatic in both FWD (U760E) and AWD (U760F) forms. Internal gearsets are the same for both; the AWD adds a power take‑off unit and rear drive module.

6‑speed automatic — U760E (FWD)

6‑speed automatic — U760F (AWD)

Note: Some non‑U.S. markets offered other engines/transmissions (e.g., a 2.0L with CVT). Ratios above reflect the U.S./Canada 2.5L automatic.

Available axle ratios

The 2015 RAV4 did not offer multiple axle ratios from the factory; instead, the final drive is fixed by drivetrain (FWD vs AWD). Most North American builds use a 4.071:1 final drive.

Notes

• Actual axle code formatting is printed as A/TM on the driver door jamb (example: “A/TM: 02A/U760F”). The “02A” axle code corresponds to the common 4.071 open differential in this generation. Minor code variations may appear by market or plant.
• The AWD system uses a matching front final drive and a rear differential coupled via an electronically controlled rear drive unit.

How to identify your axle ratio

• Toyota door‑jamb build label (A/TM): Open the driver door and locate the white certification label. On the lower portion you’ll see “A/TM.” The first group is the axle code (e.g., 02A), the second is the transmission family (e.g., U760E or U760F). Most 2015 RAV4 vehicles list 02A. If you provide that code to a Toyota parts counter, they can confirm the exact ratio.
• VIN decode/build sheet: A Toyota dealer can print a build sheet from your VIN showing axle/transmission details. Several online VIN decoders also surface the transmission family (U760E/F) and drivetrain (FWD/AWD).
• Physical inspection (AWD): On AWD models, the rear differential housing typically has a laser‑etched or stickered part number. While it may not list the ratio directly, cross‑referencing that P/N with Toyota EPC will confirm the final drive.
• For comparison: GM owners read the RPO list in the glovebox/door jamb; Ford and Ram often have a stamped axle tag on a cover bolt. Toyota uses the A/TM code instead of RPO tags.

Towing vs MPG impact

• Numerically lower final drive ratios (e.g., 3.5x) reduce engine rpm at cruise and generally improve highway fuel economy; numerically higher ratios (e.g., 4.3x) multiply torque more at the wheels for stronger launches and towing at the expense of rpm/MPG.
• The 2015 RAV4 comes with a single, relatively short 4.071 ratio that balances drivability with efficiency for the 2.5L engine. Toyota’s published tow rating is typically 1,500 lb in North America for both FWD and AWD; towing gains from AWD come mainly from traction rather than a different axle ratio.
• Tire size matters: Upsizing tires effectively “tallies” the gearing (lower engine rpm), while downsizing does the opposite. Large tire changes can push the 6AT to downshift more often on hills, which can reduce mpg.
• Real‑world cruise rpm (approx.): With 0.608 6th gear and 4.071 final, a stock‑tire RAV4 turns roughly 1,900–2,100 rpm at 70 mph. That’s why the transmission frequently uses 6th on flat highways for economy.

Common issues

While the 2015 RAV4’s U760E/F and differentials are generally reliable, owners and technicians report a few patterns as mileage climbs:

• Ring and pinion/diff whine (AWD more commonly): A light humming or whine at 40–60 mph that changes with throttle can indicate pinion bearing wear in the rear differential. Fresh gear oil and correct fill level are important; noisy units may require bearing rebuild.
• Prop shaft center support bearing (AWD): Vibration or droning under load can stem from a worn center support bearing on the driveshaft. Replacement of the support/bearing (or complete shaft assembly) cures it.
• Rear drive unit clutch chatter (AWD): The electronically controlled coupling contains a clutch pack. Contaminated or degraded fluid can cause chatter or binding during tight turns. A fluid service and calibration procedure can help; severe cases need overhaul.
• 6‑speed shift feel: Some vehicles exhibit harsh 2–3 or 3–2 shifts when hot. Toyota issued TSBs involving updated ECU/TCM calibrations—many owners report improved smoothness after reflash.

If you’re hearing gear noise, feeling vibration, or seeing leaks at the PTU/rear differential, have a driveline specialist inspect before damage escalates.
