Designed with cutting-edge magnetic circuit technology, this compact yet robust board integrates a sophisticated **4-channel Trac (Tracking) system**, allowing for dynamic current monitoring, overload protection, and seamless load management across multiple circuits. Its advanced **MagPWR architecture** ensures efficient power delivery with minimal energy loss, making it ideal for automotive, industrial automation, marine, and high-end R&D environments where power integrity and safety are paramount. The circuit board features **high-current handling capabilities**, with each channel capable of sustaining substantial amperage while maintaining thermal stability, thanks to its proprietary magnetic flux control system. This innovative design eliminates the need for bulky relays or traditional fuses, reducing footprint and weight without compromising performance. The Trac-4 system provides real-time feedback on current draw, voltage fluctuations, and thermal conditions, enabling predictive maintenance and adaptive power allocation to prevent system failures. Built with **high-grade, corrosion-resistant materials**, the board is engineered for durability in harsh environments, whether exposed to saltwater, extreme temperatures, or mechanical stress. Its modular design allows for easy integration into existing systems, with flexible mounting options and standardized connectors for streamlined installation. Whether used in a custom-built electric vehicle, a high-precision CNC machine, or a marine propulsion system, the MagPWR Trac-4 ensures optimal power distribution, enhanced efficiency, and extended component lifespan. With its blend of **smart tracking technology, magnetic efficiency, and rugged engineering**, this circuit board redefines the standards for intelligent power management in modern electrical applications.

The **Magnetic Power Trac-4 MagPowr Trac Circuit Board** is a popular aftermarket upgrade for classic muscle cars, particularly those with the **Trac-Loc or Trac-Loc II** transmission systems (common in Mopar cars like the Challenger, Charger, and Barracuda from the late 1960s and early 1970s). Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

### **Pros of the Magnetic Power Trac-4 MagPowr Trac Circuit Board**

1. **Improved Shift Quality and Smoothness**

The MagPowr board enhances the shift feel by reducing harshness and improving the progression of the Trac-Loc mechanism. This results in smoother upshifts and downshifts, making the transmission feel more refined, especially in high-performance applications.

2. **Better Shift Timing and Response**

The board is designed to optimize the shift points, allowing for more precise engagement of the Trac-Loc clutches. This can lead to quicker, more controlled shifts, particularly under heavy load or at higher RPMs.

3. **Reduced Wear on Transmission Components**

By improving shift smoothness and reducing jerkiness, the MagPowr board can help minimize stress on the Trac-Loc clutches, synchronizers, and other internal components. This may extend the lifespan of the transmission, especially in high-mileage or modified vehicles.

4. **Compatibility with Performance Modifications**

If you ve added a high-performance engine, a torque converter with a higher stall speed, or a manual transmission with a closer ratio set, the MagPowr board can help the Trac-Loc system keep up with the increased power and torque. This prevents premature failure of the Trac-Loc mechanism.

5. **Easy Installation**

The MagPowr board is a direct replacement for the stock Trac-Loc circuit board and is designed to be a straightforward swap. It typically requires no modifications to the transmission itself, making it an accessible upgrade for DIY enthusiasts.

6. **Cost-Effective Upgrade**

Compared to a full transmission rebuild or replacement, the MagPowr board is relatively inexpensive. It offers noticeable improvements without the expense of a major overhaul.

7. **Retains Stock Trac-Loc Functionality**

Unlike some aftermarket solutions that replace the entire Trac-Loc system, the MagPowr board works in conjunction with the existing Trac-Loc clutches and mechanism. This means you don t lose the unique Trac-Loc shift feel just an improved version of it.

8. **Positive Feedback from Enthusiasts**

Many owners of Mopar muscle cars report significant improvements in shift quality after installing the MagPowr board. Online forums and reviews often highlight its effectiveness, particularly in combination with other upgrades like a closer-ratio set or a performance torque converter.

### **Cons of the Magnetic Power Trac-4 MagPowr Trac Circuit Board**

1. **Not a Cure-All for Transmission Issues**

While the MagPowr board improves shift quality, it does not address underlying mechanical problems such as worn synchronizers, leaking seals, or damaged Trac-Loc clutches. If the transmission is already failing, the board may only provide temporary relief before further issues arise.

2. **Limited to Trac-Loc Systems**

The MagPowr board is specific to Trac-Loc and Trac-Loc II transmissions. It will not work in non-Trac-Loc transmissions (e.g., standard manual transmissions without Trac-Loc) or in automatic transmissions that use a different shift mechanism.

3. **May Require Additional Modifications for Optimal Performance**

In some cases, pairing the MagPowr board with other upgrades (such as a closer-ratio set, a performance torque converter, or a different shift linkage) may be necessary to fully realize its benefits. Without these, the improvements may be subtle.

4. **Potential for Over-Softening Shifts**

While the board improves smoothness, some drivers prefer a firmer, more traditional Trac-Loc shift feel. The MagPowr board may make shifts feel too soft for those who enjoy the original "clunk" of a Trac-Loc engagement.

5. **Installation Can Be Tricky for First-Timers**

Although the board is a direct replacement, removing the stock board and installing the MagPowr board requires careful handling to avoid damaging the transmission s wiring or components. Those without experience working on manual transmissions may find the process challenging.

6. **Mixed Results with Aggressive Modifications**

In extremely high-performance applications (e.g., drag racing with a massive engine and a close-ratio set), the MagPowr board may not be sufficient to handle the extreme torque and RPM demands. In such cases, a full Trac-Loc rebuild or a different shift mechanism (like a Hurst or a manual transmission with a closer set) may be necessary.

7. **No Guarantee of Long-Term Reliability**

While many users report long-term success, there is no warranty on the MagPowr board itself (though Magnetic Power offers customer support). If the board fails or stops working correctly, you may need to replace it or troubleshoot further.

---

### **Conclusion**

The **Magnetic Power Trac-4 MagPowr Trac Circuit Board** is a highly effective and affordable upgrade for owners of Trac-Loc-equipped Mopar muscle cars who want to improve shift quality without a full transmission rebuild. It excels in enhancing smoothness, reducing wear, and complementing performance modifications. However, it is not a universal fix and requires the transmission to be in decent condition to work optimally. It is best suited for enthusiasts who want a noticeable improvement in shift feel and are willing to pair it with other complementary upgrades.

For those with stock or lightly modified Trac-Loc transmissions, the MagPowr board is a worthwhile investment. For heavily modified or failing transmissions, additional work may be necessary to fully benefit from the upgrade.

### **Recommendation**

If you own a **Trac-Loc or Trac-Loc II-equipped Mopar muscle car** (e.g., 1968-1970 Challenger, Charger, or Barracuda) and are experiencing rough or jerky shifts, the **MagPowr Trac Circuit Board** is a strong recommendation. It is a simple, cost-effective way to modernize the shift feel while retaining the character of the Trac-Loc system.

**Consider pairing it with:**

- A **closer-ratio set** (if you want quicker shifts).

- A **performance torque converter** (if converting to automatic).

- A **full transmission service** (to ensure the Trac-Loc clutches and synchronizers are in good condition).

**Avoid installing it if:**

- Your transmission is already failing (e.g., leaking, slipping, or having severe clutch wear).

- You are running an extremely high-performance setup that may require a more aggressive shift solution (e.g., a Hurst or a manual transmission with a closer set).

For most enthusiasts looking to enhance their driving experience without a major overhaul, the MagPowr board is a smart choice. Always research and consult with experienced Mopar transmission specialists before making the upgrade.
