This is a flexible circuit board that installs inside the 8HP mechatronic case to bypass the original transmission controller to enable the transmission to get controlled by an external controller. It is an easier alternative to soldering wires to the conductor plate.

Unlike other such products, this being a flexible board it is less susceptible to solder joint damage by repeated thermal expansion as a rigid board is so prone to.

Comes with a metal cover to enclose the board after installation.
