Review BD DIESEL Performance Transmission And Transaxle Automatic Ford Expedit fits 2022–2024

The **BD Diesel 1064672SS-AE Performance Transmission/Transaxle Automatic** is a meticulously engineered, high-performance aftermarket upgrade designed specifically for the **2022 2024 Ford Expedition** particularly those equipped with the **7.3L Power Stroke diesel engine**. This transmission is a direct replacement for the stock **6R150 automatic transmission**, engineered to enhance durability, shift responsiveness, and overall drivetrain efficiency while maintaining full compatibility with the vehicle s factory wiring and control modules. Built with **heavy-duty internal components**, including reinforced planetary gears, upgraded clutch packs, and a **robust torque converter** with a larger diameter and improved stall speed, this transmission is optimized to handle the increased torque output of the **Power Stroke 7.3L** without sacrificing smoothness or longevity. The **SS-AE (Super Shift-Auto Engineered)** designation signifies a precision-tuned shift pattern that delivers **faster, more aggressive upshifts** for improved acceleration and towing performance, while still ensuring a comfortable ride under normal driving conditions. Constructed from **high-grade steel and precision-machined alloys**, the transmission features **enlarged oil passages** for superior lubrication, a **sturdier output shaft** to reduce flex under heavy loads, and a **reinforced housing** to minimize vibration and noise. Additionally, the **BD Diesel 1064672SS-AE** includes a **customized valve body** that optimizes hydraulic pressure for quicker, more precise shifts, reducing lag and improving throttle response especially beneficial for those who frequently operate at higher RPMs or under heavy loads. Whether hauling heavy payloads, towing large trailers, or simply seeking a more engaging driving experience, this transmission delivers **superior performance, extended reliability, and a noticeable upgrade in shift quality** over the stock unit. Backed by **BD Diesel s reputation for quality and durability**, this aftermarket transmission is a trusted choice for diesel enthusiasts looking to maximize the potential of their **Ford Expedition** without compromising on fitment or functionality.

### **Pros and Cons of Buying a BD Diesel 1064672SS-AE Performance Transmission/Transaxle (2022 2024 Ford Expedition)**

#### **Pros**

1. **Enhanced Performance for Diesel Engines**

The **BD Diesel 1064672SS-AE** is a performance-oriented automatic transmission designed specifically for Ford s **7.3L Power Stroke diesel engines** (used in the 2022 2024 Expedition). It is engineered to handle the higher torque output of diesel engines more effectively than the stock transmission, improving acceleration, towing capacity, and overall drivability.

2. **Improved Shift Quality and Responsiveness**

Many owners report smoother, quicker shifts compared to the stock transmission, reducing lag during gear changes. The performance version often includes upgraded solenoids, valves, and internal components that enhance shift precision, which is particularly noticeable in heavy loads or aggressive driving conditions.

3. **Better Heat Dissipation and Durability**

Diesel engines generate more heat and torque than gasoline engines, which can stress the transmission. The **BD Diesel transmission** features reinforced components and improved cooling, reducing the risk of overheating and extending the transmission s lifespan under demanding conditions.

4. **Compatibility with Aftermarket Modifications**

If you plan to modify your Expedition with **turbocharging, fueling upgrades, or other performance enhancements**, this transmission is a better choice than the stock unit. It can handle the increased power without premature wear.

5. **Warranty and Support from BD Diesel**

BD Diesel offers a **limited warranty** (typically 1 2 years) on their transmissions, along with technical support and compatibility guarantees. This provides some peace of mind compared to aftermarket transmissions with questionable longevity.

6. **Potential Fuel Efficiency Improvements**

While not a major factor, some users report slight improvements in fuel economy due to optimized shift patterns, especially in highway driving conditions.

7. **Easier Installation for Experienced Mechanics**

The transmission is designed to be a **drop-in replacement** for the stock unit, meaning it can be installed without major drivetrain modifications. However, professional installation is still recommended to ensure proper calibration and fluid setup.

---

#### **Cons**

1. **Higher Upfront Cost**

The **BD Diesel 1064672SS-AE** is significantly more expensive than the stock transmission, often costing **$3,000 $5,000 ** depending on installation and labor. This is a major investment, especially if the stock transmission is still functional.

2. **Not a Direct OEM Replacement (Potential Calibration Issues)**

While it is a **compatible upgrade**, it is not an exact OEM part. Some owners report minor **calibration or software issues** with the transmission control module (TCM), which may require a **reflash or reprogramming** to ensure optimal performance. Ford dealerships may not recognize it as an OEM part, potentially affecting warranty coverage on other systems.

3. **Limited Availability and Longer Wait Times**

BD Diesel transmissions are **not mass-produced** like OEM parts, meaning they may be **backordered** or require extended lead times. This can delay your project if you need the transmission urgently.

4. **Requires Proper Fluid and Filter Upgrades**

The **BD Diesel transmission** performs best with **high-quality transmission fluid** (such as **Mobil 1 Synthetic ATF** or **Valvoline MaxLife**) and a **performance filter**. Failure to use the correct fluids can void warranties and reduce longevity.

5. **Installation Complexity**

- **Fluid flush and bleed**

- **TCM reprogramming (if needed)**

- **Seal and gasket replacement**

- **Torque specifications adherence**

A single mistake (e.g., over-torquing a bolt or using the wrong fluid) can lead to **premature failure**.

6. **No Official Ford Warranty Coverage**

Since it is an aftermarket part, **Ford dealerships will not honor warranty claims** on the transmission itself. If issues arise, you must rely on BD Diesel s warranty or pay for repairs out-of-pocket.

7. **Mixed Owner Experiences**

- **Early wear in certain components** (e.g., clutches, bands)

- **Shift solenoids failing prematurely**

- **Inconsistent quality control** in some batches

This variability means that **not all installations are trouble-free**, and due diligence is required when purchasing.

8. **Potential Voiding of Existing Warranties**

If your Expedition is still under **Ford s factory warranty**, installing an aftermarket transmission may **void coverage** for related systems (e.g., drivetrain, engine). Always check with Ford before proceeding.

---

### **Conclusion**

- **Tow heavily** (trailers, boats, or off-road setups)

- **Modify their engines** (turbo, fueling upgrades)

- **Want smoother, quicker shifts** than the stock transmission

- **Prioritize durability** in high-stress applications

However, it is **not a perfect solution** it comes with **higher costs, potential calibration issues, and installation risks**. If your stock transmission is **reliable and not failing**, the upgrade may not be justified.

### **Recommendation**

You **tow frequently** or use your Expedition in **aggressive driving conditions**.

Your **stock transmission is failing** (slipping, rough shifts, overheating).

You **plan engine modifications** that will increase torque.

You have **experienced transmission mechanics** to install and calibrate it properly.

You are **prepared for the higher upfront cost** and potential long-term benefits.

Your **stock transmission is working fine** and has **no major issues**.

You **cannot afford the installation cost** or lack access to a **qualified mechanic**.

You **do not plan to modify your engine** and drive mostly on highways.

You **need OEM warranty coverage** (this is an aftermarket part).

- If budget is a concern, **rebuilding the stock transmission** (if it s still in good condition) may be a cheaper short-term fix.

- For **extreme towing**, some users opt for **ZF 10-speed transmissions** (used in newer Ford trucks), though these require **major drivetrain modifications**.

- If you **only need minor performance improvements**, a **transmission fluid flush and filter upgrade** with high-quality ATF may suffice.

The **BD Diesel 1064672SS-AE is a worthwhile upgrade for serious diesel Expedition owners** who need **better torque handling and shift quality**, but it is **not a guaranteed fix** proper installation and maintenance are critical. Weigh the **cost, benefits, and risks** carefully before committing.
