The original 4L60E as we know it today actually started out as the Turbo-Hydramatic (TH) or (THM) 400. The TH400 transmission had many variants it for other applications: TH350, TH300, TH250, TH200, 3L80, and 3L80HD. Out of all of those transmission variants, the most common were the THM400 and THM350. All of the aforementioned transmissions were some of the first 3-speed automatic transmissions that were slowly innovated until General Motors (GM) unveiled the Turbo-Hydramatic 700-R4 design in 1983. The transmission was known as the 700R4, 700-R4, TH700, TH700-R4, and THM700-R4 but was ultimately renamed to the 4L60-E we know today when it arrived in the Chevrolet Suburban and similar GM vehicles in 1993.

The next year, they added it to their RWD cars, like the Camaro and Corvette, as it proved best for all their rock-steady rides. Starting in 1996, they took this auto gearbox to the next level by adding a bolt-on bell housing and stronger internal components. With its four drive gears, the 4L60E pairs perfectly with each longitudinal factory engine option, including every high-performance LS powertrain. By 1998, it could handle up to 360 lb-ft of torque with ease. This made it the ideal option for stock, street, and race applications. Beyond that, the advanced dual-shift solenoids readied it for OBD II vehicles without making it too expensive to buy. Additionally, the 4L65-E and 4L70-E were introduced as near exact successors of the 4L60E, except with some modified components added to make them more suitable for an increased strain with larger vehicles. Even stronger variants eventually made their way into the market like the 4L80-E and 4L85-E transmissions.

Some of the most common vehicles this transmission was put in were the Chevrolet Silverado 1500, Silverado 2500, and Silverado 3500 as well as the GMC Canyon, Envoy, Safari, Savana, Sierra 1500, Sierra 2500, and Sierra 3500. Additionally, the 4L60 was used as the main transmission for the 1500 Express Van, 2500 Express Van, 3500 Express Van, Tahoe, Trailblazer, Avalanche, Cadillac Escalade, and Buick Rainier.

Despite its affordable build, this transmission quickly gained a reputation for being truly reliable, swap friendly, and easy to repair. Even better, the parts are cheap, yet high quality, though it does take a skilled transmission remanufacturing company to make it better than new. When your 4L60E transmission starts to cause problems, it's time to quickly replace it. Instead of investing in a crate 4l60e transmission or having your old 4L60e rebuilt, a remanufactured transmission may be the best choice. You can buy the highest quality remanufactured 4L60E transmissions from Reman-Transmission at the most affordable prices.

Rebuilding a transmission includes replacing worn-out or defective parts with new ones. This often, however, creates unequal wear on the different parts inside the rebuilt transmission. A remanufactured transmission means all the worn-out parts are replaced with new or re-machined parts along with every other component in the transmission assembly. A remanufactured 4l60e transmission can provide the strength and dependability you need for your transmission to last up to 200,000 miles or more. At Reman-Transmission we go beyond a rebuild, making sure the entire transmission assembly from the inside out is reconditioned and meets or exceeds OEM specifications. We replace all used parts inside the transmission bell housing with new or re-machined components.

A remanufactured transmission, such as the 4l60-e, will cost considerably less than a new one. Built right, the 4L60E will also be reliable and not fail you down the road.
