5R110W Transmission Upgrades
These are just a few of the high-performance upgrades that make our performance remanufactured 5R110W transmission one of the most durable and reliable options on the market. A heavy-duty pump recalibration and upgraded shift kit are included to reduce slippage and increase long-term durability. We TIG-weld the reverse planetary pinion pins to eliminate a known OEM design flaw, and upgrade the low one-way diode for enhanced strength under load. The low-reverse clutch spring retainer has been redesigned to prevent premature clutch failure, while pressure solenoids are replaced with upgraded units to ensure consistent and stable line pressure. Our exclusive Tru-Fat process is applied to the case, valve body, and pump to reduce cross-leaks and maintain optimal hydraulic performance.
We also precision-machine the pump with new line bore bushings to eliminate fluid leaks and improve flow capacity. All performance-spec bushings are installed to optimize internal fluid control and pressure stability. Every 5R110W transmission is polished to an OE-grade mirror-like finish of 15 RA or better to reduce friction and wear. The torque converter is fully remanufactured and rigorously tested for lock-up function, balance, leaks, and concentricity—eliminating common causes of vibration, front seal failure, and premature wear. Each unit undergoes cold and hot testing using our proprietary ADAPT (Advanced Dyno And Performance Testing) system, with full road simulation, synthetic transmission fluid, and a high-grade filtration system to ensure every build performs flawlessly before it leaves our facility.
