GM 700R4 & 4L60 GM 700R4 & 4L60 Transmissions The 700R4 Automatic Overdrive Transmission was GM’s answer to the American consumer’s desire for better fuel economy. First introduced in 1982, the 700R4 was met with wide fanfare as the ideal transmission.

The name 4L60 stands for 4-speeds, longitudinally placed, and 6000 pounds gross vehicle weight. By 1998 the 4L60-E was released broadly by GM in both 2 and 4 wheel drive vehicles. In 1993 the biggest change occurred, and the 4L60 changed to the 4L60-E. The hydraulic shifting system was changed over to an electronic system.

The 4L60E (and similar 4L65E) is a series of automatic transmissions from General Motors. Designed for longitudinal engine configurations, the series includes 4 forward gears and 1 reverse gear. The 4L60E is the electronically commanded evolution of the Turbo-Hydramatic 700R4, originally produced in 1982.

The 4L60E and 4L65E are built at Toledo Transmission in Toledo, Ohio and have also been built at Romulus Transmission in Romulus, Michigan and Ramos Arizpe, Mexico.

4l60e Problems

The two transmissions cannot be differentiated from the outside. The 4L65E shares the same exterior parts but have stronger internals such as 5 pinion planets compared to 4 in the 4L60E. 4L60E uses a 6.5' depth bell with 6 bolts for non gen 3 LS applications and a 7' depth bell with 7 bolts for LS applications. The 4L65E/70E uses a 7' depth bell and 7 bolts.

They also have different input shafts and torque converters. 4L60E's uses a 298mm input shaft for non LS and a 300mm input shaft for LS applications. 4L65E/4L70E uses a 300mm input shaft and converter designed for LS applications only.

4L60-E[edit]

The TH700R4 was renamed '4L60' (RPO MD8) following the new General Motors naming convention when the electronic version, 4L60E (RPO M30), was phased in as the 4L60 was being phased out. This happened in 1993 for trucks, vans, and SUVs, and 1994 for rear wheel drive passenger cars. In 1996, a bolt-on bell housing was phased in (along with a six-bolt tailhousing) for S-10 Trucks and S-10 Blazers and beginning in 1998 for all other applications. Beginning in 1998 a new 300mm torque converter with improved higher-capacity internals, 300mm style input shaft, and 300mm style pump was also introduced on models coupled to a Gen III Small Block. The 4L60E is rated to handle up to 360 ft⋅lb (490 N⋅m) of torque. It weighs 133 pounds without transmission fluid.^[1]

The 4L60E family of transmissions use 2 shift solenoids, initially called Shift Solenoid A & Shift Solenoid B, later changed to comply with OBD II (On Board Diagnostics revision 2) regulations to 1-2 Shift Solenoid & 2-3 Shift solenoid. By activating and deactivating the solenoids in a predetermined pattern by the PCM, 4 distinct gear ratios can be achieved. The last 4L60Es were only used in the GM Vans in 2013, before being replaced by the 6L80E. The shift solenoid pattern, also sometimes referred to as solenoid firing order, is as follows;

General Motors has produced great overdrive automatic transmissions, and the two transmissions you will hear a lot about are the 700R4 and the 4L60. These are really the same transmission, but were renamed over the years, and are considered a terrific and well-made transmission.

Key Components to the700R4 and 4L60

This transmission is positioned longitudinally and has an automatic four-speed. This family of transmissions uses a two shift solenoid. By activating and deactivating these solenoids in a specific pattern, you can get four distinct gear ratios. The transmission is constructed from cast aluminum alloy. It also utilizes a lockup torque converter. A square oil pan is also standard with this transmission type. Many performance vehicles use this transmission.

When the 700R4 came out in 1982, there was pressure to increase the fuel economy of new vehicles. The transmission was used in rear-wheel drive cars and trucks. Truck transmissions use a slightly thicker case. The biggest feature of the 700R4 was the thirty percent overdrive. Changes and improvements were made over the years the 700R4 was produced (1982 – 1990). Early versions of this transmission had a cooling circuit that used ¼ “pipe fittings, while later versions were changed to an O-ring and pinned flare design.

The 700R4 uses a 4 pin electrical connector and a TV cable. This TV Cable was very sensitive to adjustments and would fail if not adjusted properly. The TV cable is not used on the 4L60-E. The older versions also had a tendency to have seal and gasket leakage. This issue was fixed as improvements were made over the years.

4l60e Tcc Fix

The 700R4 had twenty-seven splines on the input shaft. When this transmission was renamed as the 4L60 in 1990, some small changes had been made, such as increasing the splines on the input shaft to thirty. The name 4L60 stands for 4-speeds, longitudinally placed, and 6000 pounds gross vehicle weight. By 1998 the 4L60-E was released broadly by GM in both 2 and 4 wheel drive vehicles.

4l60e

In 1993 the biggest change occurred, and the 4L60 changed to the 4L60-E. The hydraulic shifting system was changed over to an electronic system. The transmission’s transmitting core mechanically remained the same, but the clutch/band actuation systems and valve body were now controlled electronically.

The primary feedback sensor was also changed at this time to a Vehicle Speed Sensor, or VSS. This was and improvement and actually a simplification of the transmission design. The 4L60-E also underwent some changes over time. One improvement was the installation of removable bell housing. The tailhousing/adapter pattern was also modified to a rear, six bolt hex pattern.

Either one of these makes a great conversion transmission, and is adaptable for most Jeeps. Many Jeep owners switch to this transmission and benefit from a 25-30% drop in fuel consumption.

The 700R4 and 4L60 transmissions are some of the finest that GM has ever made.
