If that isn’t feasible, then you’re better off letting a mechanic do the work for you. There are several 4L60E mods you can count on as a performance enthusiast, but no matter how tempting it may be to do it yourself, you need to ensure that you are a transmission builder who has garnered a lot of experience. Now that’s out of the way, let’s show you a step by step 4L60E transmission rebuild. Today, you can find the 4L60E transmissions in GM vehicles such as: The new 4L60E featured a powertrain control module (PCM) which is able to control shifts using the feedback provided by the throttle position sensor (TPS), vehicle speed sensor (VSS), and other sensors. This led to the development of 4L60E, a computer-controlled transmission that is still based on the 700R4. Years later, the 700R4 was appended to 4L60 where the “4” denotes “four-speed”, “L” for “longitudinal installation,” and “6” for “light-to-medium-duty use and 6,000-pounds gross vehicle weight.” Despite this, the problem of shift programming which was evident in the 700R4 also reared its ugly head in the 4L60. The latter could potentially lead to the 700R4 transmission being burnt. While the TV cable was able to modulate shift programming using throttle position and vehicle speed, it was still unable to bring about a perfect balance between fuel economy, driveability, and longevity.Īnother problem that was posed, is irregularities in the line pressure and timing when a car owner improperly adjusts the TV cable. This is because its shift modulation was carried out with the use of a device known as the throttle valve (TV) cable. The 700R4 was quite unique in comparison with previous models which were designed by the company. General Motors, for instance, devised the Turbo-Hydramatic 700R4 overdrive automatic transmission in 1982 as an upgrade to the TH350 three-speed automatic. History of the 4L60E Transmissionīefore the advent of the 4L60E transmission, car manufacturers had a bone of contention while striving to bring about a vehicle’s fuel economy. These aside, there are 4L60E mods that can make your car the dream ride you’ve envisioned and that is why we’ve outlined some upgrades which you can definitely count on to build a performance car with the toughest transmission. Their attempts are evident in the use of a computer-operated carburetors and even an electronic throttle body fuel injection in a bid to slow down fuel consumption.

Now, the automatic transmission has come a long way because, for almost 40 years, car manufacturers have had their fair share of hassle while trying to design the best fuel economy engine. One way each of these can be made possible is through simple 4L60E performance transmission upgrades. It is every car lover’s dream for their vehicle to be fast, optimally use fuel, and offer an acceptable level of performance.
