Stock Transmission Limitations
OEM transmissions often suffer from inadequate cooling, limited torque capacity, and restrictive flow rates, leading to decreased performance and premature wear. The stock transmission's inability to efficiently dissipate heat can cause thermal degradation of the fluid, resulting in reduced lubrication and increased friction between moving parts.
Benefits of Upgrading
Aftermarket transmission upgrades from reputable brands like BD Diesel, Exedy, and OS Giken can significantly enhance your vehicle's performance. Upgraded transmission internals, such as gears and bearings, can withstand higher torque outputs and provide improved thermal management. Additionally, high-performance transmission pans and filters from brands like Mishimoto and Radium Engineering can increase fluid capacity and flow rates, reducing temperatures and prolonging component life.
Transmission Upgrade Options
Streetstylez offers a wide range of transmission upgrades, including crossmembers, flexplates, torque converters, and transmission rebuild kits. Our selection of transmission mounts from brands like Innovative Mounts and UMI Performance can help reduce vibration and noise, while our transmission tunnels and bell housings can improve structural integrity and reduce the risk of damage from excessive torque.
Usage Tips and Recommendations
When upgrading your transmission, it's essential to consider your vehicle's intended use and power output. For track-day enthusiasts, a high-performance transmission cooler and reinforced transmission internals are crucial for maintaining optimal temperatures and preventing damage. For those towing heavy loads, a heavy-duty torque converter and upgraded transmission pan can provide the necessary strength and cooling capacity. Consult with our experts at Streetstylez to determine the best transmission upgrade strategy for your specific needs and vehicle configuration.
