Review HONDA 88-91 Mt Right Transmission Top Mounting Rubber Motor Mount fits CIVIC CRX

The **Honda 50805-SH3-040 88-91 CRX/Civic Right Transmission Top Mounting Rubber Motor Mount** is a precision-engineered suspension component designed specifically for Honda s 1988 through 1991 CRX and Civic models equipped with the right-hand drive transmission. This high-quality rubber motor mount serves as a critical link between the transmission and the vehicle s subframe, absorbing vibrations, reducing noise, and ensuring smooth power transfer from the engine to the drivetrain. Crafted from durable, heat-resistant rubber infused with reinforced steel reinforcement, this mount is engineered to withstand the rigors of daily driving while maintaining optimal alignment and structural integrity. Its unique design accommodates the precise mounting points of the Honda 4A-GE engine and the right-side transmission, providing a secure yet flexible connection that minimizes stress on both the transmission and the engine bay components. Whether replacing a worn or failed original mount or upgrading for improved durability, this aftermarket part offers a reliable alternative to OEM components, often with enhanced longevity and resistance to cracking or degradation over time. Ideal for both restoration projects and routine maintenance, this motor mount ensures a quieter, more stable ride while preserving the performance and reliability of your Honda s drivetrain system.

### **Pros and Cons of buying a Honda 50805-SH3-040 (88-91 CRX Civic Right Transmission Top Mounting Rubber Motor Mount)**

1. **Direct Fitment** This part is specifically designed for the 1988-1991 Honda CRX Civic with an automatic transmission (SH3-040 code). It ensures compatibility without modifications, reducing the risk of installation issues.

2. **Improved Ride Comfort** Worn or cracked motor mounts can cause excessive vibration, clunking noises, and poor engine alignment. Replacing this part helps restore smooth operation and reduces stress on the transmission and engine mounts.

3. **Prevents Further Damage** A failing motor mount can lead to misalignment of the transmission, causing premature wear on internal components. Replacing it early can prevent costly transmission or drivetrain repairs.

4. **Easy Installation** As an OEM-style replacement, it should fit similarly to the original part, making it accessible for DIY mechanics with basic tools. Some aftermarket alternatives may require additional modifications.

5. **Reliability** Honda s motor mounts are known for durability, and this part is a direct replacement, meaning it should perform as expected under normal driving conditions.

6. **Cost-Effective** Compared to transmission rebuilds or engine-related repairs caused by a failing mount, this part is relatively inexpensive. It s a straightforward fix for a common wear-and-tear issue.

---

1. **Age and Wear** If the original mount was already degraded, the new part may not last as long as it would in a vehicle with less mileage. Older vehicles may experience faster wear due to general deterioration of surrounding components.

2. **Potential for Counterfeit Parts** Purchasing from untrusted sellers (especially online marketplaces) increases the risk of receiving a low-quality or fake part. Always buy from reputable suppliers or dealerships.

3. **Additional Labor Costs** While the part itself is affordable, labor costs for installation (if not doing it yourself) can add up, especially if the mount is difficult to access due to rusted bolts or tight spaces.

4. **Limited Lifespan** Like all rubber components, motor mounts eventually degrade due to heat, vibration, and age. This part may need replacement again in the future, depending on driving conditions and maintenance.

5. **Compatibility Risks** If the part is not installed correctly (e.g., misaligned or improperly secured), it could cause new issues such as binding or premature failure. Precision is key during installation.

6. **No Warranty on Aftermarket Parts** If purchasing from a non-OEM source, warranties may be limited or nonexistent, leaving you responsible for any defects.

### **Conclusion**

The **Honda 50805-SH3-040 motor mount** is a practical and cost-effective solution for restoring proper transmission alignment and ride quality in your 1988-1991 CRX Civic. Its direct fitment and reliability make it a solid choice for addressing a common wear item. However, the long-term success depends on sourcing a genuine part, ensuring proper installation, and considering the overall health of your vehicle s drivetrain.

If you re comfortable with basic mechanical work, replacing it yourself is a feasible DIY project. If not, factor in labor costs, but weigh them against the potential savings from avoiding more severe transmission or engine issues later.

### **Recommendation**

- **Buy from a trusted source** (Honda dealership, reputable online retailers, or verified eBay sellers) to avoid counterfeit parts.

- **Inspect surrounding components** (transmission mounts, engine mounts, and bolts) for signs of wear or rust before installation.

- **Follow installation instructions carefully** to ensure proper alignment and secure fastening.

- **Consider a full drivetrain inspection** if the mount failure is part of a larger pattern of wear (e.g., clunking noises, shifting issues).

- **Budget for potential future replacements** motor mounts typically last 100,000 miles but can degrade faster in rough conditions.

For most owners, this is a **worthwhile upgrade** that extends the life of your transmission and improves driving comfort. Prioritize quality and installation precision to maximize its effectiveness.
