GM’s 8l90 transmission delivers a powerful blend of performance, efficiency, and durability. Designed for high-torque engines such as the 6.2L LT1 and LT4, it is commonly used in performance cars, full-size trucks, and luxury SUVs. Its eight-speed layout provides fast, firm shifts and keeps the engine operating in the best power range. The 8L90’s advanced electro-hydraulic controls ensure precise gear changes under all driving conditions, whether cruising or wide-open throttle. This transmission is also popular among enthusiasts performing LS or LT swaps, thanks to its high torque capacity and tuning flexibility. Aftermarket support is strong, and replacement units are widely available. With appropriate cooling and regular fluid service, the 8L90 handles demanding driving, towing, and track use with confidence. For those seeking a modern GM transmission that excels in both everyday usability and performance, the 8L90 is a standout option.
