### **Pros and Cons of buying a Mopar R8447797AA 6-Speed (68RFE) Transmission for 2019 2024 Ram 2500/3500 6.7L Diesel**

#### **Pros**

1. **Improved Shift Quality and Smoothness**

The 68RFE transmission replaces the older 68RFE (pre-2019) and offers a more refined shift feel, especially in manual mode. It features a revised shift solenoid pack and improved software tuning, resulting in quicker, more precise shifts and reduced jerkiness.

2. **Better Torque Handling for Diesel Engines**

The 6.7L Cummins engine produces high torque (up to 900 lb-ft), and the 68RFE transmission is designed to handle this load more effectively than the older 68RFE. The revised gear ratios and clutch pack design reduce stress on the transmission under heavy loads.

3. **Manual Mode Functionality**

The 68RFE includes a dedicated manual shift mode (similar to a traditional stick shift), which is a significant upgrade for diesel truck enthusiasts who prefer manual control. This mode allows for more engaging driving and better fuel efficiency in certain conditions.

4. **Compatibility with Aftermarket Modifications**

The 68RFE is backward-compatible with many aftermarket performance parts, including upgraded clutches, torque converters, and shift solenoids. This makes it easier to fine-tune the transmission for towing or performance applications.

5. **Fewer Early-Model Issues Compared to Pre-2019**

While the 2019 2024 models still have some reported issues (discussed below), they are generally more refined than the early 2018 2019 versions. Ford addressed some of the initial software and shift solenoid problems in later model years.

6. **Potential for Lower Cost Than a Remanufactured Transmission**

In some cases, purchasing a used or aftermarket 68RFE transmission (especially from a reputable supplier) may be cheaper than a fully remanufactured unit from Ford or a dealer. However, quality varies, so sourcing from a trusted provider is crucial.

7. **Better Towing and Hauling Capabilities**

The revised gearing and clutch pack design improve towing performance, making it easier to handle heavy loads without excessive strain. This is particularly useful for Ram 2500/3500 owners who frequently tow trailers or carry heavy payloads.

---

#### **Cons**

1. **Shift Solenoid and Software Reliability Issues**

Some owners report intermittent shift problems, particularly in the early model years (2019 2020). The transmission may hesitate, jerk, or fail to downshift properly under heavy loads. Ford has released updates to address these issues, but some trucks may still require a software reflash or solenoid replacement.

2. **Clutch Pack Wear and Failure Risks**

The 68RFE uses a multi-plate clutch pack that can wear out prematurely, especially in high-torque applications. Some users report clutch failure as early as 50,000 100,000 miles, particularly if the truck is frequently towed or driven aggressively. Replacing the clutch pack is a labor-intensive and expensive repair (typically $2,000 $3,500).

3. **Limited Availability of Aftermarket Support**

While the 68RFE is more popular than the older 68RFE, aftermarket parts (such as upgraded clutches or torque converters) are not as widely available as they are for the Aisin AS69RC (used in some Ram models). This can make modifications more difficult and costly.

4. **Potential for Higher Repair Costs**

If the transmission fails, repairs can be expensive. While some issues (like shift solenoids) can be fixed relatively cheaply, a full rebuild or replacement may cost $3,000 $5,000 or more, depending on labor rates and parts.

5. **Mixed Reviews on Durability**

Some long-term owners report that the 68RFE is more durable than the older 68RFE, but others still experience reliability concerns. The transmission is not as battle-tested as the Aisin AS69RC or the older 68RFE in some applications, which have been around for decades.

6. **Learning Curve for Manual Mode**

While manual mode is a great feature, it requires adjustment. Some drivers find the shift points less intuitive than the older 68RFE or prefer the automatic mode for daily driving. Improper use of manual mode can lead to unnecessary wear on the transmission.

7. **Potential for Software Glitches**

Like many modern transmissions, the 68RFE relies heavily on software. Glitches or bugs in the firmware can cause erratic shifting, especially if the truck s ECU or transmission control module (TCM) is not properly updated.

---

### **Conclusion**

The **Mopar R8447797AA 68RFE transmission** is a significant improvement over the older 68RFE, offering smoother shifts, better torque handling, and manual mode functionality. It is well-suited for Ram 2500/3500 6.7L diesel owners who want a more engaging driving experience and improved towing performance. However, it is not without its drawbacks shift reliability issues, clutch pack wear, and higher repair costs are real concerns, particularly in the early model years.

If you are considering this transmission, **prioritize a well-maintained example** (preferably 2021 or later) with a clean service history. Ensure the shift solenoids and software are up to date, and consider having a transmission specialist inspect it before purchase. If you plan to tow heavily or modify the truck, budget for potential clutch replacements or additional support parts.

### **Recommendation**

- **Buy it if:** You want a modern, refined transmission with manual mode and are willing to monitor its health closely. It s a good choice for those who prioritize driving enjoyment and towing performance over long-term bulletproof reliability.

- **Avoid or reconsider if:** You need a transmission with proven long-term durability, plan to tow extremely heavy loads frequently, or cannot afford potential clutch or solenoid repairs. In such cases, a **remanufactured Aisin AS69RC transmission** (if available) or a well-maintained older 68RFE may be a safer alternative.

- **Best approach:** If possible, opt for a **2021 or newer model** with a verified service history and consider having the transmission professionally inspected before purchase. Additionally, research local aftermarket suppliers for high-quality clutch packs or shift solenoids to extend the transmission s lifespan.
