### **Pros and Cons of Buying a Lincoln EG9Z-7000 (ARM 13-15 MKZ CVT Continuously Variable Transmission)**

1. **Reliability of the CVT Transmission**

The **EG9Z-7000** is a well-regarded continuously variable transmission (CVT) used in several Toyota and Lexus models (including the 13-15 MKZ). CVTs are known for smooth acceleration, efficient fuel economy, and fewer moving parts compared to traditional automatic transmissions. When properly maintained, this transmission can last **150,000 200,000 miles** or more, especially in the MKZ where it was paired with a **2.5L or 3.5L engine**.

2. **Proven Performance in the MKZ**

The **2013 2015 Ford Mustang GT (with the same transmission)** and **Toyota/Mazda platforms** (like the **Lexus ES 350**) have shown that this CVT can handle moderate to high power outputs reliably when paired with a strong engine. The **MKZ s 3.5L V6 (F25B)** is a robust powerplant that, when tuned or modified, can push the CVT effectively if the system is upgraded (e.g., with a **torque converter upgrade** or **transmission cooler**).

3. **Cost-Effective for a Used Purchase**

- The **EG9Z-7000** is relatively common in the used market, making it easier to find than rare transmissions.

- Replacement parts (such as **pulleys, belts, and solenoids**) are widely available and reasonably priced compared to high-performance automatics.

- Labor costs for repairs are often lower than for complex multi-speed transmissions.

4. **Good for Modded Engines (With Upgrades)**

- **Upgraded torque converter** (for better torque handling)

- **Transmission cooler** (to prevent overheating under heavy loads)

- **Stronger pulley system** (some aftermarket kits exist)

- **ECU tuning** (to optimize shift points and prevent harsh engagement)

5. **Simpler Maintenance Than Traditional Automatics**

- No clutch or planetary gears mean fewer failure points.

- Fluid changes are straightforward (though **CVT fluid must be high-quality and changed at recommended intervals**).

- No need for frequent valve body or solenoid replacements (common in some automatics).

6. **Smooth Driving Experience**

The CVT provides **instantaneous acceleration** and **seamless gear transitions**, which can be appealing for daily driving or light performance use.

---

1. **Potential for Overheating Under Heavy Loads**

- CVTs are **notoriously sensitive to heat**, especially when modified for extra power.

- The **EG9Z-7000** is not as robust as a **ZF 8HP or Aisin TF80SC** in high-power applications.

- **Risk of belt wear, pulley damage, or fluid breakdown** if the transmission is pushed too hard without cooling upgrades.

2. **Limited Lifespan Under High Power**

- While stock, this CVT can handle ** 250 300 hp** comfortably, but **400 hp** will **significantly reduce its lifespan** unless heavily modified.

- **Belt stretch and pulley wear** become major concerns under sustained high loads.

- **No "gear ratios"** mean the transmission cannot handle extreme torque spikes as well as a traditional automatic.

3. **Dependence on Proper Fluid & Cooling**

- **CVT fluid must be changed every 30,000 60,000 miles** (or as recommended by the manufacturer).

- **Poor fluid quality or neglect** leads to **premature failure** (slipping, rough shifts, or complete transmission lockup).

- **No transmission cooler?** Expect **reduced lifespan**, especially in hot climates or with modifications.

4. **Potential for Slipping or Rough Shifts**

- If the **fluid is old, contaminated, or the solenoids fail**, the CVT can **slip under acceleration** or **shift roughly**.

- **Electronic issues** (e.g., TCM failure) can cause **erratic behavior**, though this is rare in well-maintained examples.

5. **Not Ideal for Extreme Power or Drag Racing**

- While some CVTs (like the **Subaru Lineartronic**) have been used in **high-power applications**, the **EG9Z-7000 is not built for it**.

- **Risk of catastrophic failure** if pushed beyond its limits without major reinforcements.

- **Not suitable for street racing or heavy towing** without significant modifications.

6. **Resale Value & Perception**

- CVTs have a **mixed reputation** among performance enthusiasts, who often prefer traditional automatics for reliability under power.

- Some buyers may **avoid CVT-equipped cars** due to past reliability concerns (though the **EG9Z-7000 is one of the more durable CVTs**).

7. **Limited Aftermarket Support Compared to High-Performance Automatics**

- While **torque converter upgrades** and **cooling solutions** exist, they are **not as developed** as those for **ZF 8HP or Aisin TF80SC** transmissions.

- **No direct "CVT tuning" software** like some automatics have for performance tuning.

---

### **Conclusion & Recommendation**

**Stock or lightly modified MKZs (250 300 hp max)** If the transmission is **well-maintained**, it can provide **reliable, smooth operation** with **good fuel economy**.

**Budget-conscious buyers** The **EG9Z-7000 is affordable to repair** compared to high-performance automatics.

**Daily drivers who prioritize smoothness over raw power** The CVT offers **instant acceleration** and **fewer mechanical issues** than a traditional automatic in stock form.

**Those who can invest in upgrades** If you **add a transmission cooler, upgraded torque converter, and high-quality CVT fluid**, it can **handle moderate power increases (350 400 hp)** without immediate failure.

**High-power builds (400 hp) without major modifications** The **EG9Z-7000 is not built for extreme power** and will **wear out quickly** without a **torque converter upgrade, reinforced pulleys, and a dedicated cooling system**.

**Drag racing or heavy towing** CVTs **struggle with sudden torque spikes** and **overheating under sustained load**.

**Buyers who dislike CVTs** If you **prefer traditional automatics** (like a **ZF 8HP or Aisin TF80SC**), the **EG9Z-7000 may not be the best choice** despite its reliability.

**Those who neglect maintenance** **CVTs require strict fluid changes and cooling** **neglect leads to premature failure**.
