6L90 Transmission Explained
- The 6L90 transmission is a six-speed hydraulically operated automatic transmission designed for longitudinal engines and particularly for rear-wheel and rear-focused four-wheel drive vehicles. Built-in 2007, this tranny consists of six forward gears and one reverse gear. The first gear ratio is 4.03, second:2.36, third: 1.53, fourth:1.15, fifth: 0.85, sixth:0.67, and the reverse at 3.07.
- Instead of the usual planetary gear set configuration, wider gear ratios were used, allowing for better performance and fuel economy. The 6L90 transmission features multiple torque ratings, which makes it suitable for different engines and applications. And also allows users to upgrade by building one with even higher torque to withstand higher engines.
