What happens here

The vehicle starts experiencing issues with the speedometer jumping around, the torque converter not locking up, and the transmission not shifting into overdrive. The driver suspects interference from an iSimple module, which has previously caused electrical problems. The co-pilot indicates the battery is at 69%. The first attempt to resolve the issue is to disconnect the iSimple module, which is wired into the dashboard and stereo system.

Goal: Identify speedometer/transmission issues and remove potential electronic interference source.
