Frequently Asked Questions
What does “Plug & Play” actually mean?
“Plug & Play” means the engine computer will arrive pre-programmed with your car’s specific Vehicle Identification Number (VIN) and current mileage. This allows it to communicate correctly with all other modules in your vehicle (like the transmission controller and anti-theft system) without any further programming. You can simply install it and start the car.
Do I need to send you my old computer?
No core charge or return is required for this part. You can keep your old module or recycle it locally, simplifying the process for you.
How do I confirm my part number?
The part number is printed on a sticker on the outside of your current engine computer. It is located in the front of the engine compartment on the driver’s side. Matching your number to 04606873AA, 04606873AB, or 04606873AC will ensure a perfect match.
Can a bad ECU cause transmission problems?
Absolutely. The engine computer works directly with the transmission control module (TCM) to control shift points and line pressure. A failing ECU can send bad data, resulting in harsh shifting, hesitation, or the transmission going into “limp mode.” Replacing the ECU often resolves these related symptoms.
Will this fit my 2002 Chrysler Concorde or Intrepid?
Yes, this unit is compatible with the 2002 Concorde (Limited, 3.5L, VIN G), Intrepid (R/T or ES, 3.5L, VIN G), and 300M (excluding Special edition) models that originally came with an engine computer identified by part number 4606873. Please check the fitment list on this page to confirm.
