| Extreme Automatics has been building 4L60Es for 10 years. Extreme Automatics 4L60E has been featured in GM HiTech and many other national magazines.
|
The Extreme Automatics 4L60E has undergone many changes over the years. We have found the one build that has been very successful for many 9 second runs in the F-Body. The most reliable 4L60E built. Our 4L60E can handle an honest 700HP. Our 4L60E is perfect for a Street/Race car.

Extreme Automatics 4L60E
The heart of the EA 4L60E is the Valve Body calibration. Great parts mean nothing if you cant keep the clutches in the transmission. We completely rebuild the valve body with new hard anodized oversize valves in the areas that we know there is a problem. This is what make the EA 4L60E so reliable. We completely eliminate the 1890 code, 3/4 clutch failure due to inadequacy in the valve body. Shifts are quick and clean. Are 4L60s don't bang!!! This trans also works well in 2wd/4wd trucks.
