Description - 8HP

WARNING: This page is about a different car, the 2021 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

The 8HP Electronic Shift Module (ESM) is part of the shifter assembly called the Electronic Shifter (E-Shifter). The E-Shifter is an electronic Shift-by-Wire device that is mounted to the vehicle center console. The E-Shifter uses Controller Area Network (CAN) messages to communicate driver requests for transmission gear changes without a mechanical connection. The E-Shifter also provides means for displaying the current and pending transmission gear state via the illuminated PRNDM pattern on the shift knob.
