6L80 vs. 6L80E – Which One to Choose?

Published by Dustin Babich on

The main difference between a 6l80 and a 6l80e is that the latter has electronic control of the transmission. The 6l80 and the 6l80e are both six-speed automatic transmissions produced by general motors’ hydra-matic division.

The 6l80e has electronic control, while the 6l80 is controlled by hydraulic systems. This means that the 6l80e can provide more precise and efficient shifting, as well as better overall control and handling. In addition, the 6l80e may also have additional features such as “tap up/tap down” gearing, which allows for manual shifting, and a “tow/haul” mode for heavier loads.
