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.

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. The most common simple DIY 4l60e upgrades that can be done with simple hand tools in your driveway without removing the transmission to tear apart are definitely transmission coolers, pans, and thermostat bypass.It is every car lover’s dream for their vehicle to be fast, optimally use fuel, and offer an acceptable level of performance. When it comes to upgrading your 4l60e, besides adding better internals and hard parts, there are a few simple upgrades that you can make to keep transmission temps down. The correct torque spec for the 4l60e transmission pan bolts is 100 – 120 inch pounds. When reinstalling the transmission pan on your 4l60e, be sure to not over tighten the pan bolts. How many quarts does it take to do a fluid and filter change on a 4l60e trans? For a typical pan drop and fluid change, you will need about 5-7 quarts to do the job.Īs always, start with adding a few quarts of atf when you have the new filter and pan back on and shift through the gears to get fluid moving and warm, then keep checking and added until you have the right level.
