Transmission Install Kit 6L80 to LS Engine

The Transmission Install Kit 6L80 to LS Engine from Chevrolet Performance is purpose-built for LS engine swaps requiring 6L80 six-speed automatic transmission integration. This kit exists because pairing a modern 6L80 transmission with a classic or contemporary LS platform demands precision engineering—factory bell housing bores, dowel pin locations, and torque converter seating surfaces must align perfectly for reliable installation. Whether you're executing a full LS swap in a vintage muscle car, Gen III/IV Corvette, or modern Camaro conversion, this kit eliminates guesswork and ensures OEM-level fitment.

This transmission install kit contains all necessary hardware, dowels, and adapter components engineered to bridge the 6L80 transmission case to LS family engine blocks (LS1, LS2, LS3, LS7, LSA, LT series). The kit accounts for dimensional variances between generations of LS engines and transmission variants, ensuring proper clutch pack clearance, input shaft alignment, and bellhousing concentricity. Chevrolet Performance specification means each component meets OEM tolerances and material standards, guaranteeing durability under sustained power delivery and thermal cycling—critical for both naturally aspirated and boosted applications.

Serious engine builders, restoration shops, and performance enthusiasts benefit most from this kit when transitioning from older TH400, TH700R4, or 4L60E transmissions to the 6L80's superior shift quality and electronic controls. Installation pairs with custom driveshaft work and requires professional transmission tuning for closed-loop electronic management. Compatible across all LS variants, this kit is non-negotiable for anyone pursuing a reliable, street-legal LS swap where transmission longevity and smooth power delivery matter.
