Engineered to Dominate, the 4L65E 4WD Mega Monster transmission is tough enough to withstand the rigors of even the toughest heavy duty trucks, used for towing/hauling or off-roading. It is ideal for vehicles powered by 4.8, 5.3, LS1, or 6.0L engines producing up to 500 horsepower with a naturally aspirated system using pump gasoline. Certified Transmission offers the following resource for those interested in knowing vehicle applications for the remanufactured 4L65E transmission. To view applications begin by selecting the vehicle manufacturer listed below.

This 4L65E transmission was produced to handle more torque than 4l60e or any other transmission in the market. Although their case is identical, the 4L60E later became the 4L65E when General Motors upgraded some key internal parts of the model. The 4L65E was a long awaited replacement for the 4L60E transmission. The 65 handled more torque and was internally redesigned to fix some inherent flaws from its predecessor. We have studied the 4L65-E transmission since its conception and have been able to build upon its success by correcting the existing flaws from its original manufacturer.

Introduced in 1993 for trucks, vans, and SUVs, then in 1994 for rear-wheel-drive passenger cars, the 4L60E from General Motors is an evolution of the Turbo-Hydramatic 700R4 and replaced the tried and true TH350. Advantages over the TH350 include lower gear ratios, improved valve body, the addition of 4th gear (overdrive), and a lockup torque converter. Popular choice for street performance and retro fitting. They are readily available on the used market and can handle 400-700 HP, depending on year and internal modifications.

Important Years

1995

• Received a pulse width modulated torque converter clutch solenoid

1996 received the most significant updates, including...

• Began receiving a bolt-on bellhousing in certain models (all models by 1998)
• Six-bolt tail shaft
• Modified 3-2 downshift solenoid

Important Note:
1996 and newer 4L60Es are not interchangeable with previous models due to these upgrades

2001

• Name designation changed to 4L65E
• Torque capacity increased as a result of the four pinion planetary carrier being replaced by a five pinion unit
• Better 3-4 clutch
• Improved input shaft
• Deeper pan for more fluid

Due to these improvements and added strength, the 2001 and later 4L65E is the most desirable for performance applications.

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.

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;
