Can a 4L60E be replaced with a 4L80E?

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. According to GM Powertrain information, the 4L60E has a maximum engine torque rating of 360 lb-ft and a maximum gearbox torque rating of 610 lb-ft.

When did the Chevy 4L80E transmission come out?

Unlike the later 4L60E transmission, the 4L80E did not feature a removable bellhousing, but an integrated bellhousing with only the Chevrolet 90 degree engine bolt pattern being available. In 1991 the 4L80E was rolled out in GM trucks, including the Sierra, Silverado, Suburban, etc. as well as the Hummer H1.

What kind of transmission harness does GMC 4L80E use?

4L80E Transmission: Pre 4L80E transmissions use a different internal wiring harness and pass-through connector. This early harness has a problem with leaking fluid at the pass-through connector. GM recommends upgrading to the newer connector and wiring harness. Because of this, we do not provide a wiring harness for it.

Is the 4L80 transmission compatible with the CJ5?

The 4L80 is doubtless a very successful OEM transmission, and a terrific conversion transmission in the right Jeeps and situations. However, with its 26-1/4″ length, it is a longer transmission and is not compatible with short-wheelbase Jeeps such as the CJ5 in any scenario, or CJ7’s if they have a lot of suspension lift.

What kind of torque converter does GM 4L80 have?

The torque converter is a fluid turbine drive and like those on its predecessor transmissions; the TH350C, 700R4, and 4L60, the 4L80 features a lock-up pressure plate for direct mechanically coupled driving from the engine crank. The 4L80 features a 310 mm torque converter. As to length, this transmission is 26-1/4″ long.

Like the other GM automatics, the 4L80E featured a die-cast aluminum case. Unlike the later 4L60E transmission, the 4L80E did not feature a removable bellhousing, but an integrated bellhousing with only the Chevrolet 90 degree engine bolt pattern being available.
