According to information, Mazda uses transmissions that are developed in-house. They incorporate the Skyactiv Technology. Mazda Motor Corporation, founded in 1920, officially began producing small trucks in Hiroshima in 1931 and started manufacturing passenger cars in the early 1960s. It boasts a comprehensive product line, covering various models such as economy cars, SUVs, and sports cars, with family vehicles consistently dominating its production line. Mazda transmissions include the 6AT automatic transmission, while manual transmission models use a 6-speed manual gearbox. Manual transmissions are used to alter the engine's speed and torque delivered to the drive wheels, enabling the car to achieve different levels of traction and speed. The 6AT designation indicates six forward gears, meaning there are six sets of gear ratios. When using Mazda transmissions in daily driving, the following points should be noted: Do not delay transmission fluid changes for extended periods. Prolonged failure to change the transmission fluid can damage internal components such as bearings and the housing. Avoid coasting in neutral for long durations. While driving manual transmission models, many experienced drivers may coast in neutral, but for automatic transmission vehicles, this can cause overheating and create a jolt when shifting back into Drive (D). Never shift into Drive (D) or Reverse (R) before the vehicle comes to a complete stop. Some drivers, aiming for smooth operation, shift into reverse while the vehicle is still moving, which can severely damage the transmission gears and lead to grinding or other failures over time. Avoid frequently climbing steep hills in Drive (D). On steep inclines, automatic transmission vehicles may overheat due to high load or shift prematurely, resulting in insufficient power. In such cases, use manual mode to lock in lower gears or switch to sport mode to protect the transmission. Do not tow the vehicle over long distances. If an automatic transmission vehicle breaks down, use a flatbed tow truck to move it onto the tow platform while the transmission is in Neutral (N). Avoid using tow ropes or directly dragging the vehicle.

Mazda's transmission is quite interesting. As an owner of an old Mazda6 for 8 years, I have a lot to say. In the early days, Mazda mainly sourced transmissions from Aisin. Now, the new Mazda3 and CX-30 Skyactiv models all use Mazda's self-developed 6AT, which they call SKYACTIV-DRIVE. The most impressive part is that Skyactiv 6AT's downshift speed is even faster than some dual-clutch transmissions I've driven, making it particularly responsive when driving on mountain roads. However, small sports cars like the MX-5 still use Aisin transmissions, as the matching is more mature. When buying a used car, pay special attention to models before 2012, as their transmissions are prone to oil leaks, and repairs can be quite expensive.

When helping a friend choose a used car, I researched Mazda's transmission systems, which follow two paths: in-house development and external collaboration. Mainstream models like the Atenza and CX-5 use Mazda's own Skyactiv transmissions, but tuning varies significantly between models. For example, the CX-5's 6AT is more comfort-oriented than the Mazda3's, with nearly imperceptible shift shocks. Here's a lesser-known fact: the imported CX-3 once used Toyota's Direct Shift-CVT, and now the hybrid version of the Axela also pairs Toyota's hybrid system with an E-CVT. During maintenance, be sure not to use the wrong transmission fluid—Skyactiv models require FZ-certified specialized fluid, as using regular ATF can cause issues.

Mazda's transmission strategy is actually quite shrewd. Mainstream models use their in-house 6AT to control costs, but they also adapt to local conditions: the Mazda2 in Southeast Asian markets uses Aisin CVT, while the Mazda3 hybrid produced in Mexican factories adopts Toyota's E-CVT. The most iconic is the first-generation Skyactiv 6AT, with an 82% lock-up range that saves 10% more fuel than conventional ATs. Note that after 150,000 km, the transmission oil pan gasket is prone to leakage. During maintenance, ask the technician to focus on inspecting the solenoid valve wiring harness - if this fails, the gear shifts can become so jerky it makes you question your life choices.
