### **Pros and Cons of Buying a DACCO 49WBJNC11 Torque Converter for a 1987 1990 Ford Mustang Aerostar**

1. **Compatibility** The DACCO 49WBJNC11 is specifically designed for Ford s 4-speed automatic transmissions (C4) used in the 1987 1990 Mustang Aerostar, ensuring proper fitment and function.

2. **Performance Improvement** A high-quality torque converter can enhance acceleration, especially in stop-and-go traffic, by improving stall speed and torque multiplication.

3. **Durability** DACCO converters are known for their robust construction, often featuring heavy-duty stamping and high-quality materials that resist warping and wear.

4. **Ease of Installation** Since it is an exact replacement, installation is straightforward, requiring only basic tools and no transmission modifications.

5. **Cost-Effective Upgrade** Compared to a full transmission rebuild or replacement, upgrading the torque converter is a relatively inexpensive way to improve drivability.

6. **Better Shift Feel** A well-built converter can reduce harsh shifts and improve overall transmission smoothness.

7. **Warranty Coverage** DACCO converters typically come with a warranty (check the specific terms), providing some protection against defects.

1. **Potential Overkill for Stock Applications** If the Aerostar s engine and transmission are in good condition, a stock torque converter may suffice, and upgrading could be unnecessary.

2. **Cost Relative to Benefits** While not extremely expensive, the price may not justify the improvement if the vehicle is lightly used or not driven aggressively.

3. **Installation Risks** If not installed correctly (e.g., improper fluid levels, misalignment, or torque specs), it could lead to transmission issues or damage.

4. **Limited Performance Gain** Unlike heavy-duty or performance converters, this is a standard replacement, so gains may be modest unless the original converter was worn or failing.

5. **Compatibility with Modifications** If the Aerostar has aftermarket modifications (e.g., performance chips, turbocharging, or engine swaps), a different converter may be needed for optimal performance.

6. **Potential for Counterfeit Parts** Purchasing from untrusted sellers could result in a fake or low-quality converter, leading to premature failure.

### **Conclusion**

The DACCO 49WBJNC11 torque converter is a solid, reliable replacement for the 1987 1990 Mustang Aerostar s C4 transmission. It offers tangible benefits in terms of performance, durability, and ease of installation, making it a worthwhile upgrade if the original converter is worn or if the vehicle sees frequent use. However, if the Aerostar is rarely driven or the transmission is already in excellent condition, the upgrade may not be necessary.

For most owners looking to restore or improve their Aerostar s drivability, this converter is a **recommended choice**, provided it is purchased from a reputable supplier and installed correctly. If budget is a concern, verifying the original converter s condition first (e.g., checking for leaks, sluggish shifts, or overheating) can help determine whether an upgrade is truly needed.

- The original converter is failing or worn.

- You want smoother shifts and better acceleration.

- You plan to keep the vehicle long-term and drive it regularly.

- The Aerostar is lightly used and the transmission is in good shape.

- You prefer to save money on a less critical component.

- You re unsure about installation and lack mechanical experience.
