2018 Toyota Camry: Transmission & Axle Gear Ratios

Transmission gear ratios

The 2018 Toyota Camry was available with two exceptional transmissions: a new Direct Shift 8-speed automatic for its gasoline-powered models and an advanced Electronically Controlled Continuously Variable Transmission (ECVT) for the Hybrid variants. Each is engineered to balance performance, responsiveness, and fuel efficiency.

Direct Shift 8-Speed Automatic (UA80E / UB80E)

This intelligent transmission was standard on all 2018 Camrys equipped with the 2.5L four-cylinder and 3.5L V6 engines. It features a close-ratio setup in the lower gears for brisk acceleration and taller gears at the top end for quiet, low-RPM highway cruising. Two versions were used to perfectly match the powerband of each engine.

Electronically Controlled Continuously Variable Transmission (ECVT)

The 2018 Camry Hybrid models (LE, SE, XLE) are equipped with Toyota's proven ECVT, which is part of the Toyota Hybrid System II. Unlike a traditional automatic, the ECVT does not have fixed "gears." Instead, it uses a planetary gearset to continuously and seamlessly vary the gear ratio, keeping the gasoline engine and electric motor in their most efficient operating range. It provides smooth, linear acceleration without any shift shock.

Available axle ratios

In a front-wheel-drive vehicle like the Camry, the "axle ratio" is referred to as the final drive ratio. It represents the last stage of gearing in the transaxle before power is sent to the wheels. Toyota selected specific final drive ratios to complement each engine and trim level's intended purpose, from maximum efficiency to sportier response.

How to identify your axle ratio

Unlike some domestic trucks, Toyota does not use a tag on the differential housing. Instead, you can easily identify your vehicle's factory-installed final drive ratio by checking the manufacturer's sticker on the driver's side door jamb.

1. Open the driver's door and locate the black-and-white sticker on the B-pillar.
2. Look for the "A/TM" label, which stands for "Axle / Transmission."
3. The code will look like this: A01A/UB80E. The first four characters (A01A) represent your axle code, which corresponds to the ratios in the table above. The characters after the slash represent your transmission model.
4. VIN Decoder: An online VIN decoder can also provide detailed build information for your specific vehicle, including its transmission and final drive gearing.

Performance vs MPG impact

While the 2018 Toyota Camry is not rated for towing, the final drive ratio still has a significant impact on its driving characteristics and fuel economy.

• Numerically Lower Ratio (e.g., 2.563:1 in the V6): This is often called a "taller" gear. It results in lower engine RPM at highway speeds. The primary benefit is improved fuel economy during steady-state cruising and a quieter cabin. Because the powerful V6 has plenty of torque, it doesn't need a high numerical ratio to accelerate quickly.

• Numerically Higher Ratio (e.g., 3.003:1 in the SE): This is called a "shorter" gear. It allows the engine to rev more quickly, which multiplies torque for better off-the-line acceleration and a sportier, more responsive feel. This is why Toyota equipped the sport-tuned SE model with a slightly shorter gear than the efficiency-focused LE trim. The trade-off is slightly higher engine RPM on the highway, which can marginally reduce fuel economy.

Common issues

The powertrain in the 2018 Camry is widely regarded as reliable, but one issue was noted with early production models equipped with the Direct Shift 8-speed automatic transmission. Some owners reported hesitation, lurching, or jerky shifting at low speeds. Toyota addressed this by issuing a Technical Service Bulletin (TSB-0077-18) and a subsequent software update for the transmission control module (TCM). Vehicles manufactured later in the model year or those that have had the update applied typically exhibit much smoother performance. The ECVT in the Hybrid models is known for its exceptional long-term durability and does not have any widespread common issues.
