Watch This 4L60E Go From Parts To Performance - Super Chevy (blog)
But alas, we have a solution to help your classic Chevy consume less gasoline but keep the fun factor at an all-time high – add an overdrive transmission to the mix. Converting to an overdrive transmission, like the Performance Automatic 4L60E unit pictured here, will help keep the revs down on the highway but also be strong enough to handle the power under the hood. The company makes it easy with dozens of different Street Smart systems with four-, five-, and six-speed automatic overdrive transmissions designed for all types of Chevy engine packages. In fact, the company even offers specific packages to mate up with most Chevrolet Performance crate engines. The Street Smart systems include an application-matched transmission that includes a torque converter, dipstick and fill-tube, trans cooler with steel braided lines, transmission mount, and other supporting hardware if needed, such as a TV-cable,... All electronically controlled Street Smart packages include a stand-alone transmission controller like an MSD Atomic trans controller or PCS unit. The 4L60E is one of Chevrolet’s most popular rear-wheel drive overdrive transmissions as it enjoyed a service life that began in 1993 as the slushbox for General Motors’ truck and SUV offerings.
