SuperMatic 4L70 details:
Based on the proven and durable Hydra-Matic 4L60-E series of four-speed overdrive transmissions, the 4L70-E delivers greater torque carrying capacity and increased strength. It’s built with heavy-duty, OEM-designed components that meet the validation and durability standards GM imposes on production-vehicle transmissions. The 4L70-E is designed for engines making up to 480 horsepower, with friction-reducing components that send more power to the axle. 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 of the 4L70-E, GMPP upgraded the 3-4 clutch pack and installed a high-energy 2-4 band. Power loss and heat buildup are diminished with the use of needle bearing assemblies and associated components, which replace conventional thrust washers. Also: special valve body enhancements were incorporated to produce shifts that are firm and quick under full power, but smooth and refined in light-throttle conditions.
