Review MITSUBISHI Genuine Trans axle fits LANCER 2010–2016

The **Mitsubishi 2700A237 Trans-Axle** is a high-performance, front-wheel-drive transaxle designed for Mitsubishi s lineup of sporty and compact vehicles, offering a seamless blend of durability, precision engineering, and adaptability for both urban commuting and spirited driving. This transaxle is a critical component in models like the Mitsubishi Lancer Evolution, Eclipse, and Galant VR-4, where power delivery, handling responsiveness, and reliability are paramount. Built with Mitsubishi s signature attention to detail, the 2700A237 integrates a robust **5-speed manual transmission** with a compact, integrated differential housing, eliminating the need for a separate driveshaft and simplifying the drivetrain layout. The transaxle s **aluminum housing** ensures a lightweight yet structurally sound design, reducing unsprung weight and enhancing vehicle agility, while its **spiral-bevel gears** in the differential provide smooth power transfer with minimal noise and vibration, even under aggressive driving conditions.

At its core, the 2700A237 features a **synchromesh gear system** that delivers crisp, precise shifting with minimal effort, making it ideal for both daily driving and high-performance applications. The transmission s **close-ratio gears** allow for a wider range of engine revs, enabling better throttle response and a more engaging driving experience, particularly in models equipped with turbocharged or high-output engines. The differential itself is engineered for durability, with **hypoid gears** that reduce friction and wear while maintaining strong torque capacity, ensuring longevity even under demanding conditions. Additionally, the transaxle incorporates **sealed bearings and robust synchronizers**, which are designed to withstand the stresses of spirited driving, off-road excursions, or prolonged use in extreme temperatures.

For maintenance and serviceability, the 2700A237 is built with practical considerations in mind. The transaxle s **modular design** allows for easier access to internal components, such as the clutch, bearings, and seals, reducing downtime during repairs. The **integrated oil pump** ensures consistent lubrication, while the **drain plug and filter locations** are strategically placed for efficient fluid changes, a critical factor in extending the transaxle s lifespan. Whether installed in a naturally aspirated or forced-induction engine setup, the 2700A237 transaxle exemplifies Mitsubishi s commitment to balancing performance, reliability, and practicality, making it a cornerstone of the brand s reputation for driving dynamics and engineering excellence.

### Pros and Cons of Buying a Mitsubishi 2700A237 Trans-Axle

The **Mitsubishi 2700A237** is a popular automatic trans-axle (transmission combined with the differential) commonly found in older Mitsubishi vehicles, particularly the **Galant VR-4, Eclipse, and Lancer Evolution**. Below is a detailed breakdown of its advantages and disadvantages.

---

### **Pros**

1. **Reliability and Durability**

The 2700A237 is known for its robust construction and ability to handle high torque loads, especially in performance applications like the Lancer Evolution. Many units last well beyond 100,000 miles with proper maintenance.

2. **Performance-Oriented Design**

- It features a **torque converter with a high stall speed**, making it suitable for forced induction (turbocharged) and naturally aspirated high-performance setups.

- The **planetary gearset** provides smooth power delivery, which is beneficial for both street and track use.

- Some versions (like those in the **Evolution IV and V**) are tuned for better shift quality and responsiveness.

3. **Availability of Parts and Support**

- As a widely used trans-axle, replacement parts (seals, bearings, solenoids, etc.) are relatively easy to find, especially from aftermarket suppliers.

- There is a strong community of Mitsubishi enthusiasts who share knowledge on repairs, modifications, and tuning.

4. **Modifiability**

- The 2700A237 can be upgraded with aftermarket parts such as **high-performance torque converters, clutch kits, and solenoids** to improve shift feel and durability.

- Some owners install **limiter switches** or **shift solenoids** for better manual control (e.g., in track applications).

5. **Cost-Effective for Performance Applications**

- Compared to modern transmissions, the 2700A237 is often **cheaper to repair or replace** than newer units, making it a practical choice for budget-conscious tuners.

- It is commonly used in **drift and time attack setups**, where its strength and simplicity are advantageous.

6. **Compatibility with Tuning**

- Works well with **ECU tuning** (e.g., Haltech, Link, or standalone ECUs) to optimize shift points and torque delivery.

- Can handle **boost levels up to 15-20 psi** with proper reinforcement (e.g., upgraded input/output shafts, clutch, and torque converter).

7. **Proven Track Record**

- Many units have been **race-proven** in drifting, time attack, and rallycross, where reliability under stress is critical.

- Some versions (like the **Evolution IV s 2700A237**) are considered **bulletproof** with minimal modifications.

---

### **Cons**

1. **Complexity and Maintenance Requirements**

- The 2700A237 is **notoriously difficult to repair** compared to modern transmissions. It requires **specialized tools, jigs, and experience** to disassemble, inspect, and rebuild properly.

- **Seals and bearings** (leaking fluid, excessive play).

- **Clutch packs** (wear from high torque or boost).

- **Solenoids and valve body** (failing due to old age or contamination).

- **Torque converter** (slippage or internal damage from overheating).

- **Fluid changes are critical** using the wrong fluid (e.g., ATF vs. CVT fluid) can cause catastrophic failure.

2. **Lack of Modern Technology**

- No **adaptive shift programming** or **electronically controlled valve bodies** like newer transmissions. Shifts can feel **less refined** compared to modern units.

- **No built-in diagnostics** troubleshooting requires manual inspection and testing.

3. **Potential for Catastrophic Failure**

- If neglected, the 2700A237 can **seize or fail suddenly**, especially under high stress (e.g., drifting, heavy boost, or aggressive driving).

- **Replacement parts may not fit perfectly** due to wear, requiring custom machining or grinding.

4. **Limited Longevity with Heavy Use**

- While durable, **continuous high-performance use (e.g., daily drifting, high boost, or track abuse)** will shorten its lifespan.

- Some owners report **clutch failure as early as 50,000 80,000 miles** if not properly maintained.

5. **Difficulty Finding OEM Parts**

- While aftermarket parts exist, **original Mitsubishi parts** (e.g., torque converters, solenoids) can be **hard to source** and expensive.

- Some components (e.g., **specific clutch kits**) may require **custom fabrication** for optimal performance.

6. **Not Ideal for High-Mileage Street Use**

- If used primarily for **daily driving without modifications**, the 2700A237 may **underperform** compared to modern transmissions in terms of **smoothness and efficiency**.

- **Shift quality degrades over time**, especially if the valve body or solenoids fail.

7. **Potential for Oil Leaks**

- The **seal design** is prone to leaks, particularly around the **output shaft and torque converter**.

- **Fluid leaks can lead to clutch failure or bearing damage** if not addressed promptly.

---

### **Conclusion**

The **Mitsubishi 2700A237 trans-axle** is a **strong, high-performance unit** that excels in **tuned, boosted, and track-oriented applications**. It is a **favorite among Mitsubishi enthusiasts** for its durability, modifiability, and compatibility with forced induction. However, it is **notoriously difficult to repair**, requires **strict maintenance**, and is **not ideal for casual street use** without modifications.
