WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 Dodge Intrepid, 2003 Chrysler Intrepid, 2003 Chrysler Concorde, 2003 Chrysler 300M, and 2002 Dodge Intrepid. However, it is still accessible from the selected car via links, so may be relevant.

The Powertrain Control Module (PCM) first senses that the speed control is set. If the set speed is exceeded by more than 4 MPH (6.5 KM/H) and the throttle is closed, the PCM causes the transaxle to downshift to 3rd gear. After downshifting, the automatic speed control resumes normal operation. To ensure that an upshift is appropriate after the set speed is reached, the PCM waits until the speed control system opens the throttle at least 6 degrees before upshifting to OVERDRIVE again.

If the driver applies the brakes, canceling automatic speed control operation with the transaxle still in 3rd gear, the PCM maintains this gear until the driver opens the throttle at least 6 degrees to avoid an inappropriate upshift. The upshift is also delayed for 2.5 seconds after reaching the 6 degrees throttle opening in anticipation that the driver might open the throttle enough to require 3rd gear. This will avoid unnecessary and disturbing transmission cycling. If the automatic speed control RESUME feature is used after braking, the upshift is delayed until the set speed is achieved to reduce cycling and provide better response.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
