Review ANCHOR Rear Automatic Transmission Mount Gmc C15 Pickup Gh fits C1500 1967–1974

The **Anchor SX-134Y Rear Automatic Transmission Mount** is a high-performance, heavy-duty suspension component meticulously engineered to provide superior stability, reduced transmission vibration, and enhanced drivability for 1967 through 1974 GMC C15 and C1500 GH models equipped with automatic transmissions. Designed to replace the stock rubber or polyurethane mounts that often degrade over time, this mount features a robust **steel-reinforced construction** with a **polyurethane bush insert**, ensuring long-lasting durability under the demanding loads of heavy-duty towing, off-roading, or daily driving. The SX-134Y is specifically crafted to accommodate the unique torque and weight requirements of these classic trucks, particularly those with **THM400, THM625, or THM720 transmissions**, by minimizing harsh vibrations that can transfer from the transmission housing to the frame, thereby reducing fatigue on both the drivetrain and the vehicle s structural components. Its **precision-machined mounting surfaces** ensure a secure, interference-free fit, while the **high-density polyurethane** provides a balance of flexibility and rigidity, absorbing shocks while maintaining alignment under extreme conditions. Whether you re hauling heavy payloads, towing trailers, or simply seeking a smoother, more refined ride, this mount eliminates the clunking, rattling, and excessive movement that plague stock units, making it an essential upgrade for enthusiasts and professionals alike who demand reliability and performance from their vintage GMC trucks. Built to withstand the test of time, the Anchor SX-134Y is a direct replacement that installs easily with basic tools, offering immediate improvements in transmission stability and overall vehicle handling.

**Pros and Cons of buying a Anchor SX-134Y Rear Automatic Transmission Mount for a 1967-1974 GMC C15/C1500/GH**

1. **Compatibility** The Anchor SX-134Y is specifically designed for your vehicle s make and model range (1967 1974 GMC C15/C1500/GH), ensuring a proper fit without modifications. This reduces the risk of misalignment or damage during installation.

2. **Durability** Anchor is a well-regarded brand in the aftermarket parts industry, known for producing high-quality, heavy-duty components. The SX-134Y is likely constructed from sturdy materials (such as steel or reinforced rubber) to handle the stress of an automatic transmission, which can be heavier and more rigid than manual setups.

3. **Reduced Vibration and Noise** A proper transmission mount helps isolate engine and transmission vibrations from the vehicle s frame, improving ride comfort and reducing unwanted noise. This is particularly beneficial in older trucks where suspension and mounting components may be worn.

4. **Prevents Transmission Whip** Automatic transmissions, especially in older vehicles, can develop a "whipping" motion if not properly supported. The SX-134Y mount helps stabilize the transmission, reducing harsh movement that could lead to premature wear on the transmission or drivetrain components.

5. **Ease of Installation** Since it s a direct replacement part, the SX-134Y should be relatively straightforward to install, assuming you have basic mechanical skills or access to a mechanic. The mounting points are likely designed to align with your vehicle s existing hardware, minimizing the need for customization.

6. **Cost-Effective Solution** Replacing a worn or damaged transmission mount is often cheaper than overhauling the entire transmission or dealing with secondary damage caused by poor support. The SX-134Y provides a targeted fix without requiring extensive labor.

7. **Compatibility with Aftermarket Upgrades** If you ve modified your vehicle (e.g., lifted suspension, performance engine, or heavy-duty towing setup), a reinforced mount like the SX-134Y can help accommodate additional stress without compromising drivability.

---

1. **Potential Overkill for Mild Use** If your truck is used primarily for light-duty tasks (e.g., daily driving, short trips, or minimal towing), a standard OEM-style mount or a less aggressive aftermarket option might suffice. The SX-134Y is a heavy-duty part, which could be unnecessary if your transmission isn t subjected to extreme stress.

2. **Installation Challenges** While the part is designed for your vehicle, installation may still require disassembling parts of the drivetrain (e.g., removing the transmission or exhaust components) to access the mount. If you re not comfortable with this process, labor costs could add up.

3. **Cost Relative to OEM** The SX-134Y is an aftermarket part, so it will likely be more expensive than an original equipment mount (OEM) if available. However, OEM mounts for older GMCs can be difficult to find, making the Anchor part a practical alternative.

4. **Quality Variability** While Anchor is reputable, aftermarket parts can sometimes have inconsistencies in manufacturing. Ensure the part you purchase is new and from a trusted seller to avoid receiving a defective or poorly made unit.

5. **Limited Customization** The SX-134Y is a standard design for your vehicle range. If you need a mount with unique adjustments (e.g., for extreme angles or custom builds), you may need to explore specialty manufacturers or custom fabrication.

6. **Potential for Over-Tightening** Heavy-duty mounts can sometimes require more torque to secure properly. Over-tightening bolts can strip threads or damage the mount or surrounding components if not done carefully.

7. **Warranty Limitations** Aftermarket parts often come with shorter or more limited warranties compared to OEM components. If the mount fails prematurely, you may be responsible for replacement costs without manufacturer support.

The **Anchor SX-134Y rear automatic transmission mount** is a solid choice for owners of a 1967 1974 GMC C15/C1500/GH, particularly if you re experiencing transmission whip, excessive vibration, or suspect your current mount is failing. Its heavy-duty construction, compatibility, and durability make it a practical upgrade for trucks subjected to moderate to heavy use, towing, or performance modifications. However, if your vehicle is lightly used or you re on a tight budget, weighing the necessity of a heavy-duty mount against the cost is advisable.

For most owners dealing with transmission-related issues or planning to tow frequently, the **benefits outweigh the drawbacks**, making the SX-134Y a recommended purchase. If you re unsure about installation, consult a mechanic to ensure proper fitment and secure attachment.

Purchase the **Anchor SX-134Y** if you need a reliable, heavy-duty replacement mount for your GMC s automatic transmission. Verify the part s authenticity and compatibility with your specific year/model before buying, and consider professional installation if you lack experience with transmission work. This upgrade will likely improve drivability, reduce wear on your transmission, and extend the lifespan of your drivetrain components.
