Review KIA 6-speed Gearbox Automatic Transmission Oem fits SORENTO AWD 2016–2018

The **Kia Sorento (GA1GK17, 2016-2018) with AWD and a 6-speed automatic transmission (H812 gearbox)** is a versatile and robust SUV designed to deliver a perfect blend of comfort, capability, and modern technology for both urban commuting and off-road adventures. Built on Kia s proven **GMA platform**, this second-generation Sorento features a refined yet spacious cabin with thoughtful ergonomics, ensuring a comfortable ride for up to seven passengers while maintaining an impressive cargo capacity of **86.3 cubic feet** when the rear seats are folded a practicality that makes it ideal for families, road trips, or hauling gear. The **AWD (All-Wheel Drive) system** enhances traction and stability across a variety of surfaces, from wet roads and light snow to gravel and moderate off-road terrain, thanks to its **torque vectoring capabilities** and **low-range gearing** (available in the **SX trim and above**), which provide added control when tackling challenging landscapes.

Under the hood, the **2.4L DOHC I4 engine (GDI)** produces **187 horsepower and 175 lb-ft of torque**, paired seamlessly with the **6-speed automatic transmission (H812)**, which offers smooth, responsive shifting and efficient fuel economy for daily driving. The **AWD system** is integrated with the transmission to optimize power delivery, ensuring balanced performance whether you re accelerating on the highway or navigating slippery conditions. For those who prioritize fuel efficiency, the Sorento achieves an **EPA-estimated 20 city / 27 highway MPG** in its standard FWD configuration, though AWD trims may see a slight reduction in efficiency due to the added drivetrain components.

The **interior of the 2016-2018 Sorento** exudes a blend of durability and modern sophistication, with high-quality materials like **soft-touch plastics, wood or aluminum trim accents (depending on trim level), and a dual-zone automatic climate control** that ensures passenger comfort year-round. The **7-inch touchscreen infotainment system** (with optional **Bluetooth, USB ports, and a rearview camera**) keeps drivers and passengers connected, while the **8-inch digital instrument cluster** provides clear, easy-to-read information, including fuel economy, trip data, and vehicle status. Higher trims, such as the **SX, EX, and Limited**, come equipped with additional luxuries like **leather-trimmed seats, power-adjustable front seats, a sunroof, and a premium audio system**, elevating the driving experience to near-luxury levels without sacrificing the SUV s rugged practicality.

Safety is a cornerstone of the Sorento s design, featuring **standard stability control, traction control, electronic stability program (ESP), and multiple airbags**, along with **rearview camera and blind-spot monitoring** (available on higher trims). The **front-wheel-drive base model** offers a more fuel-efficient option, while the **AWD variant** provides the confidence of all-season capability, making it a standout choice for drivers who need reliability in diverse conditions. With its **low ground clearance (8.3 inches)** and **approach/departure angles (21.5 /21.5 )**, the Sorento strikes a balance between on-road comfort and light off-road versatility, though it is not designed for extreme off-roading like a true off-road SUV.

Externally, the Sorento retains the **bold, family-friendly styling** of its generation, with a **sleek front grille, LED daytime running lights (on select trims), and a rugged yet aerodynamic silhouette** that turns heads on the road. The **17-inch alloy wheels** (standard on most trims) add a touch of sportiness, while the **available **blacked-out exterior accents** and **LED taillights** give it a more premium look. Whether parked in a driveway or cruising down a scenic highway, the Sorento s **spacious design, refined ride quality, and advanced features** make it a compelling choice for those seeking a **reliable, family-oriented SUV** that doesn t compromise on performance or practicality.

For buyers looking for a **well-rounded, mid-size SUV** with **AWD capability, a smooth automatic transmission, and a focus on both comfort and utility**, the **2016-2018 Kia Sorento (GA1GK17)** delivers an exceptional value proposition. With its **durable construction, modern amenities, and Kia s reputation for long-term reliability**, this model stands out as a smart investment for drivers who demand a vehicle that can handle daily life s demands while still offering the occasional thrill of an adventurous road trip.

### **Pros and Cons of Buying a 2016-2018 Kia Sorento (GA1GK17, AWD, 6-Speed Automatic, H812 Engine)**

#### **Pros**

1. **Reliability and Durability** The Kia Sorento from this generation is known for its robust construction, particularly with the **H812 3.5L V6 engine**, which is a proven powerplant with good longevity when maintained properly. Kia s reputation for durability has improved significantly in recent years, and this model is no exception.

2. **Strong Engine and Performance** The **3.5L V6 (H812)** produces **275 hp and 262 lb-ft of torque**, providing solid acceleration and towing capacity (up to **5,000 lbs** with the proper hitch). The **6-speed automatic transmission** (A6MF2) is smooth and reliable, though some owners report minor delays in shifting under heavy load.

3. **All-Wheel Drive (AWD)** The **AWD system** is well-integrated and performs well in light snow and off-road conditions, making it a practical choice for drivers in variable weather or light off-roading.

4. **Spacious Interior** The Sorento offers **ample cargo space (up to 88.3 cu. ft. with seats folded)** and a **comfortable three-row seating layout**, though rear legroom is tight for taller passengers. The front cabin is well-padded with decent sound insulation.

5. **Good Safety Features** Standard equipment includes **stability control, traction control, multiple airbags, and a backup camera**. Some trims also come with **forward collision warning, lane departure alert, and blind-spot monitoring**, which are valuable for safety.

6. **Affordable Maintenance Costs** Kia parts are generally **cheaper than those for Japanese or German competitors**, and labor costs are reasonable. The **oil change interval (5,000 7,500 miles)** is more frequent than some rivals, but this is standard for V6 engines.

7. **Resale Value** While not as strong as some luxury SUVs, the Sorento holds its value better than many competitors in its class, especially when well-maintained.

8. **Comfortable Ride** The suspension is **softer than some rivals**, making for a smoother ride on highways, though it can feel slightly floaty over rough roads.

9. **Available Tech (Higher Trims)** Some trims include **Bluetooth, USB ports, a 7-inch touchscreen, and a rear entertainment system**, which add convenience.

10. **Good Warranty Coverage** If purchased **new or CPO (Certified Pre-Owned)**, the Sorento comes with **Kia s 5-year/60,000-mile basic warranty** and **10-year/100,000-mile powertrain warranty**, which is excellent for used buyers.

#### **Cons**

1. **Transmission Issues (6-Speed Automatic)** Some owners report **rough shifting, delayed engagement, or even complete failure** of the **A6MF2 transmission**, particularly in high-mileage examples. This is a known weakness, and **transmission fluid changes should be done every 30,000 50,000 miles** to mitigate risks.

2. **Poor Fuel Economy** The **3.5L V6 averages around 18 20 MPG combined**, which is **worse than many rivals** (e.g., Toyota Highlander, Honda Pilot). Expect higher fuel costs, especially on long trips.

3. **Rear Seating Comfort** The **third row is tight**, with limited headroom and legroom, making it uncomfortable for adults on long drives. The **middle row is more usable but still cramped** for larger passengers.

4. **Infotainment System (Lower Trims)** The **basic touchscreen (7-inch) is outdated** compared to competitors like Toyota or Honda, with **slow response times and limited connectivity**. Higher trims have better features, but even then, the system feels **clunky**.

5. **Build Quality Variances** Some units have **plastic interior panels that feel cheap**, and **panel gaps can be noticeable** compared to more premium SUVs. Rust can also be an issue in **salted climates** if the undercarriage isn t properly maintained.

6. **Towing Limitations** While the Sorento can tow **up to 5,000 lbs**, it lacks **proper towing packages** (like a trailer brake controller) on base models. Towing puts extra strain on the **transmission and drivetrain**, so buyers should ensure proper maintenance.

7. **Resale Depreciation** The Sorento **loses value faster than some rivals** (e.g., Toyota Highlander, Ford Explorer), so if you plan to sell later, this could be a drawback.

8. **Off-Road Capabilities Are Limited** While the AWD helps, the Sorento is **not a true off-roader**. It lacks **locking differentials, high ground clearance, or serious off-road tuning**, making it better suited for **light trails and snow** rather than rugged terrain.

9. **Noise Levels** Some owners report **wind and road noise** at highway speeds, though this varies by model year and trim.

10. **Recall History** Check the **NHTSA website** for recalls, as some **2016 2018 Sorentos** had issues with **transmission fluid leaks, electrical gremlins, and airbag system malfunctions**.

### **Conclusion**

The **2016 2018 Kia Sorento (GA1GK17, AWD, 6-speed auto, H812)** is a **solid mid-size SUV** that offers **reliability, space, and decent power** at a reasonable price. It excels in **daily driving, family use, and light towing**, but has **notable weaknesses** particularly with the **transmission, fuel economy, and interior tech**.

- Buyers who prioritize **space, durability, and affordability** over cutting-edge tech.

- Those in **snowy or mixed-weather climates** who need AWD.

- Drivers who **maintain the vehicle well** (regular transmission fluid changes, oil services, and inspections).

- You **need excellent fuel economy** (consider a hybrid or diesel alternative).

- You **plan to tow heavily** (the transmission may struggle under sustained load).

- You **hate outdated infotainment** (the touchscreen is basic).

- You **want a premium feel** (interior materials feel more budget-conscious).

---

### **Recommendation**

If you find a **well-maintained example** (under **100,000 miles**, with **service records**, and **no transmission issues**), the **2016 2018 Kia Sorento is a great value**. Focus on:

**Transmission health** Ask for **service records** and **listen for shifting smoothness**.

**Underbody condition** Check for **rust** (especially in snow belts).

**Fuel system** Ensure **no carbon buildup** (common in V6 engines).

**Suspension** Test for **excessive bounce or clunks** (could indicate worn bushings).

**Best Trim to Buy:** **EX or SX** (higher trims have better tech and features without being overpriced).

- If **transmission concerns** are a dealbreaker, look for a **Toyota Highlander (V6) or Honda Pilot (V6)** both have more reliable automatics.

- If **fuel economy is a priority**, consider a **Hyundai Santa Fe Hybrid** or a **diesel Toyota Sequoia** (if towing is needed).

- If **off-roading is important**, a **Ford Explorer (with AWD and off-road package)** or **Chevy Traverse (with optional AWD)** may be better suited.

**Final Verdict:** **Buy if you find a well-cared-for example with no transmission red flags.** The Sorento is **underrated for its class** and can be a **great long-term SUV** when properly maintained.
