### **Pros and Cons of Buying a Dacco 87TZQMQ14 Auto Transmission Torque Converter for 1979 1984 Jaguar XJ12/XJS**

1. **Compatibility** The Dacco 87TZQMQ14 is specifically designed for the Jaguar XJ12 and XJS models from 1979 to 1984, ensuring a proper fit without major modifications.

2. **Performance Match** The torque converter is engineered to work with the 5.3L (313ci) and 6.0L (360ci) Jaguar V12 engines, providing adequate torque multiplication for these high-performance applications.

3. **Durability** Dacco is a reputable manufacturer known for producing high-quality torque converters with robust construction, including stamped steel stators and durable seals.

4. **Ease of Installation** Since it is a direct replacement, installation should be straightforward for a mechanic with experience in Jaguar transmissions, requiring only basic tools and alignment.

5. **Compatibility with Stock Transmissions** Works seamlessly with the original 4-speed automatic transmissions found in these models, reducing the need for additional modifications.

6. **Warranty Coverage** Dacco typically offers a warranty (usually 1 2 years), providing some protection against manufacturing defects.

7. **Better Shift Feel** A well-matched torque converter can improve shift smoothness and reduce harshness compared to a worn-out original unit.

1. **Cost** A new Dacco torque converter is more expensive than an OEM replacement part, ranging between **$300 $500** depending on availability and retailer.

2. **Potential Overkill for Mild Use** If the vehicle is primarily driven in light conditions (e.g., short trips, low-speed city driving), the torque converter may be more powerful than necessary, leading to slightly less efficient fuel consumption.

3. **Requires Professional Installation** While the part itself is straightforward, improper installation (e.g., misalignment, incorrect fluid levels) can cause transmission issues, so professional fitting is recommended.

4. **Limited Aftermarket Support** Unlike OEM parts, Dacco converters may not be as widely stocked by every Jaguar specialist, potentially delaying repairs if issues arise.

5. **Possible Compatibility Quirks** Some owners report minor adjustments (e.g., torque converter housing alignment) may be needed to ensure perfect operation, though this is rare with a quality part like Dacco.

6. **Not a Complete Transmission Fix** If the transmission itself is worn (e.g., valve body, planetary gears), replacing just the torque converter will not fully restore performance additional repairs may be needed.

### **Conclusion**

The **Dacco 87TZQMQ14 torque converter is a strong choice** for Jaguar XJ12/XJS owners looking to restore or upgrade their automatic transmission. It offers **reliable performance, compatibility, and durability**, making it ideal for both daily driving and enthusiasts who want to maintain their vehicle s original character while improving shift quality.

However, it is **not a budget-friendly option**, and its benefits are most noticeable in **high-performance or heavily used applications**. If the transmission is otherwise in good condition, this converter will significantly extend its lifespan and improve drivability.

For **mildly used vehicles or those with minor transmission wear**, it is a worthwhile investment. For **extremely high-mileage or severely degraded transmissions**, consider evaluating the rest of the transmission (e.g., fluid condition, internal wear) before committing.

### **Recommendation**

- You want a **direct, high-quality replacement** for a smooth-shifting transmission.

- Your vehicle has **moderate to high mileage** and needs a torque converter upgrade.

- You plan to **keep the car long-term** and want to avoid future transmission failures.
