The Mitsubishi Eclipse GSX is a beloved sports car known for its turbocharged performance and all-wheel drive capabilities. However, when pushing the limits of power, especially over 400 horsepower, the stock transmission can struggle to keep up. This article will explore various transmission upgrades that can help you handle that power without slipping.
Understanding the Stock Transmission
The stock transmission in the Eclipse GSX is a 5-speed manual or a 4-speed automatic, depending on the model year. While it is capable of handling moderate power levels, it is not designed for extreme performance. The components can wear out quickly under high-stress conditions, leading to slipping and potential failure.
Key Upgrades for Enhanced Performance
- High-Performance Clutch
- Upgraded Transmission Fluid
- Short-Throw Shifter
- Transmission Mounts
- Aftermarket Torque Converter (for automatic transmissions)
High-Performance Clutch
A high-performance clutch is essential for handling increased horsepower. Look for clutches that offer a higher torque rating and are made from durable materials. Brands like ACT and Exedy provide excellent options that can withstand the rigors of high-power applications.
Upgraded Transmission Fluid
Using upgraded transmission fluid can significantly improve performance. Synthetic fluids often provide better lubrication and heat resistance, which is crucial for high-power applications. Consider fluids specifically designed for performance vehicles to enhance shifting and reduce wear.
Short-Throw Shifter
A short-throw shifter can improve the driving experience by reducing the distance between shifts. This upgrade not only enhances the feel of the transmission but can also lead to quicker gear changes, which is beneficial when managing high horsepower.
Transmission Mounts
Upgrading to stiffer transmission mounts can help reduce movement during hard acceleration. This stability can prevent misalignment and slipping, providing a more solid connection between the engine and transmission, especially under high torque conditions.
Aftermarket Torque Converter
For those with automatic transmissions, an aftermarket torque converter can significantly enhance performance. Look for converters that offer a higher stall speed, which allows the engine to reach optimal RPMs faster, improving acceleration and overall performance.
Additional Considerations
In addition to the upgrades mentioned, consider the following aspects to further enhance your Eclipse GSX’s transmission performance:
- Regular Maintenance: Keep up with fluid changes and inspections.
- Cooling Solutions: Consider adding a transmission cooler to manage heat.
- ECU Tuning: Optimize engine performance for better transmission response.
Conclusion
Upgrading the transmission in your Mitsubishi Eclipse GSX is crucial for handling 400+ horsepower without slipping. By investing in high-performance components and maintaining your system, you can ensure your vehicle performs reliably under extreme conditions. With the right upgrades, your GSX can be a formidable contender on the road or track.
