GM has presented a new transmission solution
for high-horsepower builds during the SEMA 2019 exhibition. Company’s
representatives say that the new 6-speed automatic unit named as SuperMatic 6L80E
ensures an impressive performance/efficiency ratio when paired with Chevrolet
Performance’s (CP) LS and LSX crate engines.

In fact, this solution is a modified version of the HydraMatic 6L80E unit installed in a variety of RWD models manufactured by GM. The new unit is complemented with specific spare parts that significantly increased its torque capacity (up to 881 Nm). This is a 45% boost when compared to a standard 6L80E unit, making it an ideal choice for performance-oriented cars.

The new transmission is also notable for a “deep” 4.02 first-gear ratio, which is good for powerful engines capable of intensive operation right from the start. The 0.67 ratio top gear also facilitates to reduction of RPM rates on highways, preventing unreasonable high engine revs and ensuring optimized fuel consumption. This gear shifting solution is a part of GM’s product line of “Connect & Cruise” solutions, which are intended for coupling of a wide range of CP crate engines. A comprehensive chart in the CP catalog contains a description of the required elements and their IDs, simplifying a search process for an ideal powertrain solution.
According to CP representatives, Connect & Cruise systems allow engineers to save much time when it comes to selecting the right powertrain combination for specific projects. When a customer selects a specific engine, the system automatically finds a Chevrolet-recommended transmission and specifies the required accessories that will be necessary for a proper installation. The new transmission will be also available to order from the new brand’s catalog.
