Chevrolet Performance SuperMatic 6L80-E Transmissions 19417102

This listing covers the Chevrolet Performance SuperMatic 6L80-E as a standalone transmission, a 6-speed automatic built on an OEM-style die-cast aluminum case with a deep steel pan, sold as a kit rather than bundled with a specific torque converter here.

What is built into this unit

The case runs a slip-on yoke and a first gear ratio of 4.02:1, with electro-hydraulic, clutch-to-clutch shift control and a wiring harness included for installation. A torque converter is included with this kit, but a flexplate, transmission controller, cooler, and fluid are not, so plan for those separately. The bellhousing bolt pattern matches Chevrolet applications.

Fitting it into a build

Chevrolet Performance built the 6L80-E family to run behind its LS and LSX crate engines, and the aluminum case is designed to keep weight down without giving up strength. Because the transmission is supplied without a cooler or dedicated controller in this kit, budget time and parts for wiring it into your chosen engine management setup.

Q: Does this transmission include its own fluid? No, transmission fluid, a dipstick, and a flexplate are not part of this kit and need to be sourced separately.

Q: Is a wiring harness included? Yes, a wiring harness ships with this transmission to help with installation, though the controller itself is not included.

Q: Does it come with a flexplate or fluid? No, a flexplate, fluid, and dipstick are left out of this kit, so plan on sourcing those along with a cooler before putting the transmission into service.
