transmission control- 4l80e

i have seen online where you can buy a controller to control a 4l80e transmission with a standalone controller and force it into a manual mode or auto mode, it also tells the computer in the truck that everything is fine and working correctly. i was wondering if anyone has done this with a board or had any experience in trying.

What is a 4180e?

Please post a link to the datsheet.


its the model of a gm transmission for a truck.
