    Greater performance with enhanced efficiency is the cornerstone of a growing movement in environmentally conscious hot-rodding. One of the best ways to improve drivability and drastically improve the efficiency of your street rod, resto-mod muscle car or classic truck is installing a modern, electronically controlled automatic overdrive transmission. The new GM Performance Parts SuperMatic 4L70-E transmission P/N 19244043 - is designed to complement high-performance engines with exceptional efficiency, strength and the shift characteristics enthusiasts demand. Based on the renowned Hydra-Matic 4L60 series of four-speed overdrive transmissions, the 4L70-E delivers greater torque carrying capacity and increased durability - and it's built with the highest quality OEM parts. It is designed for engines making up to 480 horsepower. Construction and feature highlights include: * A 13-vane pump with a heat-treated stator support * Five-pinion input and reaction carriers * High-performance 2/4 servo * Heat-treated sun shell * Heavy-duty low roller clutch assembly To further increase the performance and long term durability, GMPP upgraded the 3-4 clutch pack and installed a high-energy 2-4 band.
