Review DRIVEFIX Automatic Transmission Oil Cooler Control Bypass Valve Gmc Sierra

The **DriveFix 13596738 Automatic Transmission Oil Cooler Control Bypass Valve** is a precision-engineered component specifically designed to maintain optimal hydraulic performance and thermal regulation within the automatic transmission system of a **GMC Sierra** (and compatible GM full-size trucks). This high-quality bypass valve plays a critical role in the transmission s cooling circuit by controlling the flow of transmission fluid through the oil cooler, ensuring efficient heat dissipation while preventing excessive pressure buildup. Crafted from durable materials and engineered to meet or exceed OEM specifications, this valve is built to withstand the demanding conditions of heavy-duty towing, off-road use, and high-performance driving, where transmission temperatures can fluctuate dramatically. The bypass mechanism operates automatically, adjusting fluid flow based on system demands directing cooler fluid through the heat exchanger when necessary to prevent overheating, while seamlessly shifting back to standard circulation when the transmission is operating within normal temperature ranges. This intelligent regulation not only extends the lifespan of the transmission fluid and cooler but also helps prevent costly failures associated with overheating, such as clutch slippage, delayed shifts, or even complete transmission lockup. Ideal for both replacement and upgrade applications, the DriveFix valve is a direct-fit solution that ensures seamless integration with the GMC Sierra s transmission cooling system, offering reliable performance and peace of mind for drivers who demand durability and efficiency. Whether addressing a malfunctioning valve, upgrading an existing system, or performing routine maintenance, this component is a testament to DriveFix s commitment to providing dependable, high-performance automotive parts that restore and enhance vehicle functionality.

**Pros and Cons of buying a DriveFix 13596738 Automatic Transmission Oil Cooler Control Bypass Valve for GMC Sierra**

1. **Direct Compatibility** This part is specifically designed for the GMC Sierra, ensuring a proper fit without modifications. It is engineered to match the transmission s oil cooler control system, reducing the risk of leaks or improper function.

2. **Improved Transmission Performance** The bypass valve regulates oil flow to the cooler, preventing overheating and ensuring optimal lubrication. A faulty valve can lead to transmission slippage, rough shifting, or premature wear, so replacing it can restore smooth operation.

3. **Prevents Coolant Contamination** If the valve fails, transmission fluid can mix with coolant, leading to severe damage. This part helps maintain a clean fluid system, extending the life of both the transmission and the cooling system.

4. **Easy Installation** DriveFix parts are often designed for straightforward replacement, requiring minimal tools and time. Many users report being able to install it themselves with basic mechanical skills.

5. **Cost-Effective Solution** Replacing a single valve is significantly cheaper than overhauling the transmission or replacing the entire cooler system. It addresses a specific issue without unnecessary expense.

6. **Warranty and Reliability** DriveFix is a reputable aftermarket brand known for quality components. The part should last as long as the original, provided it is installed correctly and the transmission is maintained properly.

7. **Prevents Further Damage** Ignoring a failing bypass valve can lead to costly repairs, such as transmission failure or engine damage from overheating. Addressing it early can save money in the long run.

1. **Aftermarket Part Concerns** While DriveFix is a trusted brand, some purists prefer OEM (original equipment manufacturer) parts for peace of mind. There is a slight risk of compatibility issues if the part does not match the exact specifications of the original valve.

2. **Potential Misdiagnosis** If the transmission symptoms (e.g., overheating, rough shifts) are caused by something other than the bypass valve (e.g., low fluid, worn clutches, or a failing cooler), replacing just the valve may not resolve the issue. A professional diagnosis is advisable before purchasing.

3. **Installation Challenges** Depending on the vehicle s age and condition, accessing the valve may require removing other components (e.g., the transmission pan or cooler lines). Rust, corrosion, or tight tolerances could complicate installation, especially for inexperienced DIYers.

4. **Limited Availability of OEM Parts** If the original valve is no longer available from GMC, some buyers may prefer an OEM-equivalent part. However, DriveFix is a reliable alternative, and many mechanics endorse it.

5. **Cost Compared to OEM** While still affordable, the price of an aftermarket part may be slightly higher than a discounted OEM replacement if available. However, the difference is usually minimal compared to the cost of transmission repairs.

6. **Risk of Counterfeit Parts** Purchasing from untrusted sellers (e.g., third-party marketplaces) could result in counterfeit or low-quality replicas. Buying directly from DriveFix s authorized dealers or reputable retailers mitigates this risk.

7. **No Long-Term Guarantee** Like all mechanical parts, the lifespan of the bypass valve depends on usage, maintenance, and driving conditions. Heavy towing, extreme temperatures, or neglect could still lead to premature failure.

The **DriveFix 13596738 Automatic Transmission Oil Cooler Control Bypass Valve** is a **highly recommended replacement part** for GMC Sierra owners experiencing transmission overheating, rough shifting, or coolant contamination issues. Its **direct compatibility, cost-effectiveness, and ease of installation** make it a practical choice for both DIY enthusiasts and professional mechanics. The part addresses a critical component that, if failed, can lead to **expensive transmission damage**, so replacing it is a **proactive and cost-saving measure**.

However, **buyers should ensure the symptoms are indeed linked to the bypass valve** (e.g., transmission fluid mixing with coolant) before purchasing. A **pre-purchase inspection or consultation with a mechanic** can confirm whether this is the correct fix. Additionally, **purchasing from an authorized DriveFix dealer** ensures authenticity and quality.

For most GMC Sierra owners facing these issues, **this is the right part to buy**, provided it is installed correctly and the transmission is otherwise in good condition. It strikes a balance between **affordability, reliability, and performance improvement**, making it a **strong recommendation** for those seeking a straightforward solution.

**Buy the DriveFix 13596738 bypass valve** if you have confirmed it is the source of your transmission issues.
