Chevrolet Performance 19417102 Supermatic 6L80-E, 3000 Stall

This Chevrolet Performance SuperMatic 6L80-E is the 3000-stall kit, built around a 6-speed automatic with upgraded internal components rated for 650 lb-ft of torque, a 45 percent jump over regular production versions of the same 6-speed. Chevrolet Performance pairs it with its own LS and LSX crate engines for a 2WD build. How the gearing is set up A deep 4.02:1 first gear is tuned for strong launches, while the 0.67:1 top gear keeps highway cruising efficient; the full spread runs 4.02, 2.36, 1.53, 1.15, 0.85, and 0.67 through sixth. Chevrolet Performance sells this transmission in two torque-converter configurations, and the kit described here is the one built with a 3000-stall converter, carrying part number 19417102. Choosing between the two kits The alternative kit pairs the same 6L80-E with a 2400-stall converter instead, under a different part number, so match the stall speed to your engine's power band and intended use rather than picking on price or gear count alone. Both share the same gear ratios and torque rating. Q: Will this work behind any Chevrolet V8? It is built to bolt up behind the LS and LSX family of Chevrolet Performance crate engines in a rear-wheel-drive setup, so confirm compatibility with your specific engine before ordering. Q: What changes between the two stall options? Only the torque converter and its part number differ between the 3000-stall and 2400-stall kits; the transmission itself is the same unit.
