Review CHOICE AUTOMOTIVE Rear Eng Mounts And Hyd Lh Trans Mount 3pcs Chevrolet 1.2l fits TRAILBLAZER 2021–2025

The **A20118 Rear Mount Hydraulic LH Transmission Mount (3-Piece Set)** is a high-performance, precision-engineered suspension component designed specifically for the **Chevrolet Trailblazer (2002 2011)**, particularly models equipped with the **1.2L Ecotec engine and automatic (Hydraulic) transmission**. This robust three-piece mount set replaces the stock rear transmission mounts, providing enhanced stability, reduced transmission vibration, and improved driveline isolation critical for maintaining smooth power delivery and minimizing harshness during acceleration, braking, and cornering. Crafted from durable, heat-resistant rubber and reinforced steel components, these mounts are engineered to withstand the rigors of daily driving while absorbing shocks from the transmission s hydraulic linkage, preventing premature wear on the transmission itself and surrounding chassis points. The **left-hand (LH) rear mount** in this set is meticulously designed to fit seamlessly within the Trailblazer s undercarriage, ensuring a secure and snug installation that resists sagging or misalignment over time. Whether you re tackling rough roads, towing light loads, or simply seeking a quieter, more refined ride, this mount set delivers a noticeable reduction in transmission chatter and drivetrain noise, making it an ideal upgrade for enthusiasts and fleet operators alike. Built to meet or exceed OEM standards, these mounts are a straightforward yet effective solution for restoring confidence in your vehicle s transmission support system.

### **Pros and Cons of buying a A20118 Rear Mount Hydraulic LH Transmission Mount (3-Piece Set for Chevrolet Trailblazer 2002-2011, 1.2L Engine)**

#### **Pros:**

1. **Compatibility** This mount is specifically designed for the Chevrolet Trailblazer (2002 2011) with a 1.2L engine, ensuring a proper fit without modifications.

2. **Durability** Made from high-quality materials, these hydraulic mounts are built to withstand heavy loads and reduce transmission vibration over time.

3. **Noise Reduction** Hydraulic mounts dampen engine and transmission noise better than solid rubber mounts, improving cabin comfort.

4. **Ease of Installation** The 3-piece set replaces the stock mounts efficiently, and many users report straightforward installation with basic tools.

5. **Extended Lifespan** Properly installed hydraulic mounts can last significantly longer than worn-out stock mounts, reducing long-term maintenance costs.

6. **Improved Ride Quality** By isolating vibrations, these mounts contribute to a smoother driving experience, especially on rough roads.

7. **Prevents Transmission Damage** Worn mounts can cause excessive stress on the transmission, leading to premature failure. Replacing them helps maintain transmission health.

#### **Cons:**

1. **Cost** Compared to basic rubber mounts, hydraulic mounts are more expensive, which may be a concern for budget-conscious buyers.

2. **Installation Complexity** While not extremely difficult, replacing transmission mounts requires lifting the vehicle and accessing the undercarriage, which may be challenging for inexperienced DIYers.

3. **Potential for Leaks** Hydraulic mounts contain fluid, and if they develop leaks, they may fail prematurely, requiring replacement sooner than expected.

4. **Limited Availability** Since these are specialized parts, they may not be as widely stocked as common OEM or aftermarket items, potentially requiring online ordering.

5. **Noise Transfer (If Improperly Installed)** If not installed correctly, hydraulic mounts can sometimes transfer noise differently than expected, though this is rare with proper installation.

6. **Weight Consideration** Hydraulic mounts are slightly heavier than rubber alternatives, which may have a negligible but minor impact on fuel efficiency.

### **Conclusion**

The **A20118 rear mount hydraulic set** is a solid upgrade for Chevrolet Trailblazer owners (2002 2011, 1.2L) looking to eliminate transmission rattle, reduce noise, and improve ride comfort. The benefits in durability, noise reduction, and long-term transmission protection outweigh the minor drawbacks, such as cost and installation effort. For those who prioritize a smoother, quieter ride and are willing to invest in quality parts, this is a worthwhile purchase.

If you're comfortable with basic mechanical work, installing these mounts yourself is feasible and cost-effective. However, if you're unsure about the process, consulting a professional mechanic may be advisable to ensure proper installation and avoid potential issues like leaks or improper fitment.

### **Recommendation**

**Buy this product if:**

- You experience noticeable transmission vibration or noise in your Trailblazer.

- You want a long-term solution that improves ride quality and protects your transmission.

- You re willing to invest in higher-quality mounts for better performance than stock rubber options.

**Avoid or reconsider if:**

- You re on a tight budget and can t afford the upfront cost.

- You lack mechanical experience and aren t comfortable with undercarriage work.

- Your vehicle s mounts are only slightly worn, and you re unsure if an upgrade is necessary.

For most Trailblazer owners dealing with transmission-related noise or wear, this is a **highly recommended upgrade**. Pair it with proper installation techniques (e.g., using the correct torque settings and sealant) to maximize its lifespan and effectiveness.
