The **Mazda 8TN0-42-7279** transmission, specifically designed for the **2018 2021 Mazda CX-5** equipped with **AWD (All-Wheel Drive) and an automatic transmission**, represents a refined fusion of Mazda s legendary **Skyactiv-Drive** technology and advanced powertrain engineering. This compact yet robust **6-speed automatic transmission** is engineered to deliver seamless shifting performance, enhanced fuel efficiency, and reliable durability, all while maintaining Mazda s signature driving dynamics. The **Skyactiv-Drive** system, which integrates optimized valve timing, direct injection, and a lightweight yet high-strength transmission housing, ensures that power from the **2.5L Skyactiv-G engine** (or the optional **2.0L turbocharged Skyactiv-G**) is transferred efficiently to the wheels, whether in **2WD or AWD mode**.

The transmission s **6-speed configuration** allows for smooth gear progression, reducing wear while optimizing acceleration and cruising efficiency, making it ideal for both city commuting and highway driving. Built with **high-quality materials**, including **aluminum-alloy casings** and **precision-machined gears**, this transmission is designed to withstand the demands of daily driving while maintaining long-term reliability. Whether navigating tight urban streets, winding mountain roads, or off-road adventures, the **8TN0-42-7279** ensures a **precise, responsive, and engaging** driving experience that aligns with Mazda s commitment to **performance, efficiency, and driver-centric design**.

### **Pros and Cons of Buying a 2018-2021 Mazda CX-5 (8TN0-42-7279) with AWD and Automatic Transmission**

#### **Pros**

1. **Reliable Skyactiv-Drive Transmission**

- Mazda s Skyactiv-Drive automatic transmission is known for smooth operation and durability, especially when maintained properly. It avoids the common issues found in some competitors transmissions, such as harsh shifts or frequent failures.

- The AWD system (Mazda s AWD with rear-wheel bias) provides better traction in snow, rain, and off-road conditions compared to FWD, making it a practical choice for drivers in varied climates.

2. **Strong Engine Performance**

- The 2.5L Skyactiv-G engine (used in these models) delivers solid power (187 hp, 186 lb-ft torque) with good fuel efficiency (around 22-25 MPG combined, depending on driving conditions).

- The engine is known for longevity if serviced regularly, with fewer issues compared to some turbocharged rivals.

3. **Comfortable and Refined Ride**

- The CX-5 offers a well-balanced suspension setup that provides a smooth ride on highways while still handling rough roads decently.

- Interior quality is above average for the segment, with durable materials and a quiet cabin, which is a rarity in many SUVs in this price range.

4. **Good Resale Value**

- Mazda SUVs hold their value better than many competitors, meaning you ll get a fair trade-in value if you decide to upgrade later.

- The AWD version may retain value slightly better than FWD due to its broader appeal in snowy regions.

5. **Safety Features**

- Standard equipment includes Mazda s i-Activsense suite (adaptive cruise control, blind-spot monitoring, rear cross-traffic alert, and lane-keep assist), which enhances safety without requiring expensive add-ons.

- The CX-5 has performed well in crash tests (IIHS Top Safety Pick in some trims), making it a safer choice than many budget-friendly alternatives.

6. **Low Maintenance Costs**

- Mazda vehicles are generally cheaper to maintain than German or luxury brands, with fewer complex systems that can break down.

- The AWD system is relatively straightforward compared to some competitors, reducing long-term repair risks.

7. **Practicality and Space**

- The CX-5 offers a good balance of cargo space (31.5 cu. ft. behind seats) and passenger comfort, making it suitable for families or daily commuters.

- The AWD version doesn t sacrifice much cargo room compared to FWD models.

---

#### **Cons**

1. **Higher Purchase Price for AWD**

- The AWD version costs more upfront than the FWD model, which may be a deterrent for budget-conscious buyers.

- The price gap can be significant, especially if you don t live in a region where AWD is essential.

2. **Fuel Economy Trade-Off**

- While the 2.5L engine is efficient, the AWD system can reduce fuel economy slightly compared to FWD (expect around 20-23 MPG combined instead of 22-25 MPG).

- If fuel savings are a priority, FWD may be a better choice for highway driving.

3. **Limited Off-Road Capability**

- The AWD system is not designed for serious off-roading. While it helps in light snow or mud, it lacks features like locking differentials or higher ground clearance found in dedicated off-road SUVs.

- Tire selection and suspension tuning are more important for off-road performance than just AWD.

4. **Infotainment System Limitations**

- The iDrive system (depending on the year) can feel outdated compared to modern rivals with larger touchscreens and better connectivity (Apple CarPlay/Android Auto).

- Some users report occasional lag or glitches, though this is not unique to Mazda.

5. **Resale Depreciation**

- While Mazda SUVs hold value well, they still depreciate over time. If you plan to keep the vehicle for many years, the initial cost may not be fully recovered at resale.

- The AWD version may depreciate slightly faster than FWD due to lower demand in non-snowy regions.

6. **Potential Transmission Issues (Rare but Possible)**

- While the Skyactiv-Drive transmission is reliable, like all automatics, it can fail if not maintained properly (e.g., neglected fluid changes). Always verify service history.

- Some early 2018 models had minor software glitches in the transmission, but these were largely fixed by 2019.

7. **Interior Materials Feel Basic**

- While durable, the interior plastics and trim feel more utilitarian than premium, especially compared to competitors like Honda or Toyota.

- Higher trims (Touring or Signature) improve this, but base models may feel less luxurious.

---

### **Conclusion and Recommendation**

The **2018-2021 Mazda CX-5 AWD with the Skyactiv-Drive automatic transmission** is a **strong, practical choice** for buyers who prioritize reliability, comfort, and moderate off-road capability without the complexity of high-performance or luxury SUVs. It excels in **daily driving, fuel efficiency, and long-term durability**, making it ideal for families, commuters, or drivers in snowy or mixed climates.

- You need AWD for occasional snow or rough roads but don t require serious off-road ability.

- You want a **low-maintenance, smooth-driving SUV** with good resale value.

- You prefer Mazda s **refined ride and practicality** over flashy features.

- You re willing to pay a slightly higher upfront cost for the AWD advantage.

- You **don t need AWD** and want to save money on fuel and purchase price.

- You prioritize **cutting-edge tech** (e.g., larger touchscreens, advanced driver aids) over Mazda s more conservative approach.

- You plan to **tow heavy loads** (the CX-5 has limited towing capacity, around 1,500 lbs).

- You re looking for **luxury or sporty handling** (the CX-5 is more about comfort than performance).

This Mazda CX-5 is a **smart buy for the right buyer** one who values **reliability, practicality, and AWD without unnecessary complexity**. If you find a well-maintained example with a clean service history, it will likely serve you well for **100,000 miles** with proper care. However, if you re in a **warm climate** or don t need AWD, an FWD model would be a more cost-effective alternative. Always **test drive, check maintenance records, and inspect for fluid leaks** before purchasing.
