The 4L60e is surely an computerized shift, four-speed overdrive, longitudinally positioned transmission. It's now regarded as the most beneficial rendition with the finest overdrive computerized transmission actually manufactured.
Heritage Ahead of the Late 4L60e transmission, there was the Turbo 700R, which was presented in 1982. The 4L60e is GM's prosperous continuation of the ever-improving 700R4 (aka "4L60" considering that 1990), presented in 1982. The 4L60-E will be the electronically shift managed version in the 4L60. The Late 4L60e was released in 1997 in and thoroughly phased into huge use as a result of GM by 1998 in the two RWD motor vehicle platforms (which include the C6 Corvette) and trucks in the two 2wd and 4 wheel drive configurations.

Mechanically, the transmission's electrical power transmitting core remained the identical as its predecessor, nevertheless the valve body and actuation method for the clutches, bands, and many others. is controlled by digital actuators and solenoids. A Motor vehicle Pace Sensor (VSS) is applied since the principal comments sensor, which feeds the PCM or ECM (car or truck powertrain laptop) the data to create shift judgements. The engineering of this system is simply not considered a complication, but an elegant simplification and further more improvement to this transmission. The 4L60-E derives its designation from its requirements: 4-speeds, Longitudinally positioned, 6000 lbs. GVW, Electronically managed, although the transmission sees manufacturing facility provider in trucks as many as 8600 lbs.
The strength of the 4L60-E has turned out to become exceptional. Now a darling of the transmission making aftermarket, the 4L60-E is capable of transmitting impressive strength from the two truck and functionality car apps.

The Late 4L60-E transmission provides a about three piece situation of solid aluminum alloy; bellhousing, most important situation, and tailhousing. GM shortened the deal to 21.9" extended - equal to some guide transmission of fifteen.4". The input shaft has 30 splines. The transmission typically has pinned flare & o-ring fittings over the passenger side for a cooling circuit. The transmission features a square oil pan. The critical distinction from the Later 4L60-E (1997-2006) in the Early 4L60-E (1992-1997) or 4L60 (1990-1992) or 700R4 (1982-1989) is the six-bolt "hex" rear result or tailhousing / adapter pattern. The earlier types featured a four-bolt sq . bolt design at the adaptor or tailhousing. Furthermore, the removeable bellhousing can also be one more differentiating function. Two-wheel-drive variations possess tailhousings and commonly a prolonged result shafts compared to four-wheel-drive variations, which may have numerous adaptor devices along with a reduced end result shaft.

The transmission weighs 146 pounds dried out, and 162 wet. It will take 8.4 quarts (9.64" torque converter) or 11.4 quarts (11.81" torque converter) of Dextron III fluid, which the factory claims for being a lifetime fill. Deep pan versions require around 14 quarts. Length and volume with the cooling circuit will vary and will require an more amount. The 4L60E is now concurrently created along with its strengthened progenitors; the 4L65-E and the 4L70-E. They share most components and improvements collectively. The 4L65-E was presented in 2001 as an HD edition on the 4L60-E. It contains a stronger planetary and a strength-improved output shaft.
