### Pros and Cons of Buying a DACCO 68BTNSR88 Auto Transmission with Torque Converter for a Chevrolet Impala (Deville Brougham Chassis)

1. **Compatibility and Fitment:** The DACCO 68BTNSR88 is specifically designed for the Chevrolet Impala platform, including the Deville and Brougham chassis variants from the late 1960s. This ensures a proper fit without major modifications, reducing the risk of alignment or performance issues.

2. **Performance and Durability:** DACCO transmissions are known for their robust construction and ability to handle high torque loads, which is beneficial for muscle cars, heavy-duty applications, or modified engines. The torque converter included in this package is designed to handle the power output of stock or mildly built engines, improving acceleration and drivability.

3. **Reliability:** DACCO transmissions are built with high-quality materials and precision machining, which often translates to longer-lasting components compared to aftermarket alternatives or rebuilt factory units. Many owners report fewer leaks, smoother shifts, and fewer internal failures over time.

4. **Customization Options:** The 68BTNSR88 is a "build-your-own" transmission, meaning you can select the exact components you need, such as clutch packs, synchronizers, or shift linkage, to match your engine s power or driving preferences. This flexibility allows for tuning the transmission to your specific needs, whether for street use, drag racing, or towing.

5. **Support and Community:** DACCO has a strong reputation in the classic car and performance community. Buyers often have access to forums, manuals, and technical support from experienced enthusiasts who have installed similar transmissions. This can be invaluable for troubleshooting or installation guidance.

6. **Cost-Effective Alternative:** While the upfront cost may be higher than a rebuilt factory transmission, the long-term reliability and performance gains often justify the investment. It can also be more cost-effective than constantly repairing a failing stock or aftermarket transmission.

7. **Improved Shift Quality:** The 68BTNSR88 is designed with modern tolerances and materials, which can result in smoother shifts compared to older factory transmissions that may suffer from wear or improper maintenance. This is particularly noticeable in high-performance applications.

---

1. **High Initial Cost:** The DACCO 68BTNSR88 is not a cheap transmission. The cost of the kit itself, plus the torque converter, installation labor, and additional components (such as a new bellhousing or linkage), can add up quickly. This may be a significant investment for owners on a tight budget.

2. **Installation Complexity:** While the transmission itself is well-engineered, installing it especially in a classic car can be labor-intensive. It may require removing the engine, crossmember, or other components, and precise alignment is critical. If you lack mechanical experience, this could lead to costly mistakes or delays.

3. **Learning Curve:** The "build-your-own" aspect of the DACCO transmission means you ll need to research and select components carefully. Mismatching parts (e.g., clutch packs for too much power) can lead to premature failure or poor performance. Newer buyers may find this overwhelming without guidance.

4. **Torque Converter Limitations:** The torque converter included with the kit is typically designed for stock or mildly built engines. If you plan to install a high-performance engine (e.g., a big-block Chevy with 500 horsepower), you may need to upgrade to a heavier-duty converter, which adds to the cost and complexity.

5. **Availability of Parts:** While DACCO is reputable, some specialized components (e.g., rare synchronizers or seals) may not always be in stock. This could cause delays if you need to order parts separately.

6. **Potential for Overkill:** If your engine is relatively low-powered (e.g., a stock 327 or 350 V8), the DACCO transmission may offer more performance than you need. In such cases, a rebuilt factory transmission or a lighter aftermarket unit might suffice, saving money without sacrificing reliability.

7. **Warranty Considerations:** DACCO offers warranties on their transmissions, but they may not cover labor or installation errors. If something goes wrong post-installation, you ll need to address it yourself or with a trusted mechanic, which could incur additional costs.

The DACCO 68BTNSR88 auto transmission with torque converter is an excellent choice for owners of a Chevrolet Impala Deville or Brougham chassis who prioritize reliability, performance, and longevity especially if they plan to run a moderately to highly modified engine. Its precision engineering, customization options, and strong reputation in the classic car community make it a compelling upgrade for enthusiasts willing to invest the time and money.

However, it is not the best option for everyone. If your budget is limited, your engine is low-powered, or you lack mechanical experience, a rebuilt factory transmission or a simpler aftermarket unit might be more practical. The key is to weigh the long-term benefits against the upfront costs and your own technical comfort level.

---

- You have a high-performance or heavily modified engine (or plan to build one) and need a transmission that can handle the power.

- You value reliability and are willing to invest in a transmission that will last decades with proper maintenance.

- You re comfortable with a complex installation or have access to a mechanic experienced with classic car transmissions.

- You want the flexibility to customize clutch packs, synchronizers, or other components for optimal performance.

- Your engine is stock or low-powered, and you d be better served by a rebuilt factory transmission or a lighter aftermarket unit.

- You re on a tight budget and cannot afford the upfront cost or potential installation challenges.

- You lack mechanical experience and are unsure about the installation process or troubleshooting.

- You prioritize simplicity and want a plug-and-play solution without customization.

- If you re unsure, start with a rebuilt factory transmission (e.g., from a reputable shop like Mopar or a classic car specialist) to test the waters before committing to a DACCO build.

- For drag racing or extreme power applications, research heavier-duty transmissions like the DACCO 68BTR or other high-performance options designed for those specific needs.

- Consult with experienced Impala owners or forums (e.g., ClassicChevy.com, DACCO forums) to gather firsthand insights from those who have installed the 68BTNSR88.
