Which 4L80E do I have?
With all GM longitudinal transmissions, it is far and away easiest to identify them by the amount of bolts on the transmission pan. Only the TH350 and TH400 share the same number of bolts. So if you count the bolts and get 17 you can be sure that you have identified the 4L80E transmission.
How can you tell the difference between a 4L60E and a 4L80E transmission?
Appearance. The 4L80E can be told apart from the 4L60E by looking at their transmission fluid pan. This is because the 4L80E has a pan that is oval in shape whereas a rectangular pan is featured by the 4L60E. Another disparity between both devices is the number of bolts used to secure the transmission to the engine.
Can a 4L80E replace a 4L60E?
The 4L80E has a maximum engine torque rating of 440 lb-ft and a maximum gearbox torque rating of 885 lb-ft. What this boils down to is that the 4L80E offers an 80 lb-ft and 275 lb-ft improvement over the 4L60E in both areas, respectively.
How much HP can a 4l80 handle?
In short, Performance Automatic yields a 4L80E engineered to handle 700+ horsepower and comparable torque.
Will a 4L80E transmission replace a 4L60E?
The 4L80E has been used in a number of 1/2-, 3/4-, and 1-ton GM trucks over the years. Upgrading from the 4L60E to the 4L80E is akin to going from a Dana 44 axle to a Dana 60–you’ll add some weight, but also add durability.
What do I need to swap a 4L60E to a 4L80E?
A 4L80E converter is a different bolt pattern from a 4L60E. So even if you use a spacer, you need to have a converter with a 4L60E bolt pattern and a 4L80E pump end.
What kind of transmission does a Ford 4L80E have?
The 4L80E transmission is the advanced progeny of the legendary TurboHydramatic TH400 automatic transmission, and is based heavily on the 400 in both parts and strength, yet featuring an added overdrive gear, a lock-up torque converter and advanced electronic controls.
What’s the difference between a 91 and 93 4L80E?
The control system is the same for all 4l80e’s with 1 exception. 91-93 4l80e’s used a different pressure control solenoid that required a clean8ng cycle every 10 seconds where the solenoid was stroked from full open to full closed and back to normal operation. In 94 they changed to a solenoid that didn’t require it.
Where is the speed sensor on a 1991 4L80E?
For instance, 1991 – 1996 4L80E’s have a speed sensor that is located at the driver’s side rear portion of the case. On the other hand, the 1997 and later 4wd applications may lack the rear sensor. 4L80E TRANSMISSION APPLICATIONS
What causes erratic shifting on a 4L80E?
Erratic shifting: The 4L80E had shifting problems as a result of a failed throttle position sensor or input/output speed sensor. Overheating: Transmission fluid helps to remove heat generated from the moving internal components in the transmission.
