The GM 4L60E / 4L65E / 4L70E Transmissions

4 Forward gears
Longitudinal mount (rear-wheel drive)
60 Relative torque rating 360 lb ft
Electronic valve body

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


  • 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


  • 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.
