In 1997, the electronically controlled-shift version became available in rear-wheel-drive cars and two- and four-wheel drive trucks. The number of lug nuts indicates the rating of the truck, and 6 lug nuts generally indicate a light-duty truck. Using 2 springs gives the trans a very firm shift, using all 3 is for full-race applications only and will probably be too harsh for the street. A Rear Clutch Spring Compressor, Universal Pump Remover, Front Pump Alignment Band, Turbine Shaft Installer, and a Teflon Stator Shaft Installer, are all needed to properly disassemble and reassemble the 4L60E transmission. This transmission is still used in a small number of applications, but has been replaced for the most part. Upgrading to the 5-pinion front carrier is advisable in towing applications and where horsepower numbers are above 500. The most common of these is the 90 degree V6 and V8 Bellhousing.
Transmission rebuilding requires specialized tools that are not found in your average toolbox. You can now jump down to the year identification guide. These numbers can differ a lot and you will get a lot of different answers of how much these can handle. And there are a few specialized tools needed to correctly complete the job. The number of lug nuts indicates the rating of the truck, and 6 lug nuts generally indicate a light-duty truck. Maximum shift speeds are 6,400 rpm from first to second gear, 6,200 rpm from second to third gear and 5,600 rpm from third to fourth gear. The separator plate rests between the transmission case and the valve body.
What this means is the options installed at the factory, rather than any options installed by a dealer. The 4 indicates that this is a 4 speed transmission, with it being an automatic transmission in this case. Although, everyone would agree that the transmission got better as time went on. The 4L65-E transmission's model number refers to its basic features: it is a four-speed transmission, is positioned longitudinally and is electronically controlled. The 4L60E transmission was first introduced in 1992 as an upgrade or replacement to the transmission, also known as the 4L60 transmission. This transmission is significantly heavier than the 4L60E with a dry weight of 254 pounds.
The 4L65E utilizes 5-pinion planetaries, along with a hardened input shaft, that boosted torque capacity to 380 ft. The replacement began in 1996 but was not fully phased in until 1998. It is an evolution of the , originally produced in 1982. A few of the new features added with the 4L80E in comparison to its predecessor were electronic controls, overdrive capability, and a lock-up torque converter. The 4L60E is rated to handle up to 360 ft·lbf 488 N·m of torque. This article relies largely or entirely on a single. If your car model came from the factory with the 4l80e, get a dipstick from a transmission that has been fitted in one of these cars.
There is no leaking coming from the front seals, rear sears or oil pan. But to check the level warm the car to operating temp. This unit is made of overall thicker material and includes a new thrust washer. This unique piece offers 40% more surface area for better holding power in 4 th gear. Another feature of this transmission is the cooling ports that allow for transmission oil coolers to be used. The nice thing about all of this is that the 5-lug parts are easily swapped into the 4L60E, leaving you with the ability to upgrade your existing tranny without having to buy a new unit.
The 4L60E transmission was first introduced in 1992 as an upgrade or replacement to the 700R4 transmission, also known as the 4L60 transmission. The Beast sun gear right is made of thicker material and is particularly beefy around the neck, where they are prone to sheering. After the upgrade, the car has a nice, snappy shift under part-throttle, and the full-throttle shifts are supersharp, much better than the stock slush box and more reliable, too. There is some adjustment to be made here though. The 4L60 and 4L60E are essential the same. Some of the most popular car applications were the Chevrolet Corvette, Camaro, Caprice, and Impala, just to name a few. The L indicates that the engine is longitudinally positioned.
The 4L60E uses 4-pinion planetary carriers, these carriers are rated to 360 ft. The transmission matches longitudinal engines. The 4L60E also uses a 4-pinion front planetary carrier, which is more expensive than the rear unit. Complementary 300mm pumps and input shafts rounded out the improvement. The 22 years of usage is a testament to its robustness and strength. The 3-4 gear clutches reside in the drum, this is where the Z-pack comes in.
It is told exactly when to shift by the computer and it allows for more accurate conditions based shifting. The sixth-generation Chevrolet Corvette was also equipped with the 4L60E transmission. The stock parts have a tendency to sheer off the gear at the neck in high-performance applications. This is important as while they share some parts, they are different transmissions. Here are a few characteristics that all years share. It also allowed for more than one set of shift points to be programmed into the transmission, which allowed for tow haul mode in the trucks and high performance modes for muscle cars.

The 2001- and later model 4L65E features a completely new design, eliminating the failure-prone features. Just with these number, you can probably calculate that there is a big difference in size and weight between these transmissions. According to Super Chevy, the truck version rates at 380 pound-feet of torque and nearly 400 pound-feet of torque in the car version. These are specifically designed to not bow and to have superior holding power.
