Greater performance with enhanced efficiency is the cornerstone of a growing movement in environmentally conscious hot-rodding or "e-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.
GM Performance Parts SuperMatic 4L70E transmission is designed to compliment high-performance engines with exceptional efficiency, strength and the shift characteristics enthusiast demand.
Based on the renowned Hydramatic 4L60 4 speed overdrive transmissions, the 4L70E delivers greater torque carrying capacity and increased durability. Built with the highest quality OEM parts, it is designed for engines making up to 480 horsepower.
Construction features and 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 and Heavy-duty low roller clutch assembly
To further increase the performance and long time durability, GM Performance Parts upgraded the 3-4 clutch pack and installed a high-energy 2-4 band. Power loss is diminished with the use of needle bearing assemblies and associated components, which replace conventional thrust washers.
The new SuperMatic 4L70-E is the perfect compliment to a GM Performance Parts crate engine, creating a bulletproof powertrain for any project you can dream up.
