Laymans terms

This code means that a part inside the car's transmission is stuck and not moving like it should. It's like when a toy gets jammed and won't work right.

Explanation

The transmission uses friction elements like clutches and bands to change gears. This code indicates that one of these elements, specifically 'F', is not releasing properly.

Technical description

P07AD is a diagnostic trouble code (DTC) for a transmission issue where the friction element, designated as 'F', is stuck in the 'on' position. This can prevent the transmission from shifting properly and may lead to further mechanical issues if not addressed.

Symptoms
