Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your car.
Is this part difficult to install?
The TCM on the 2003-2004 Saturn ION is located behind the driver’s side (LH) strut tower in the engine bay. For someone with basic mechanical skills and tools, it is a straightforward replacement. Since it comes pre-programmed, no special electronic tools are needed. Always disconnect the battery before starting any electrical work.
Will this fix my specific transmission problem?
This module is the solution for a wide range of electronic transmission faults. If you are experiencing symptoms like harsh shifting, error codes for shift solenoids, or communication failures, this part is very likely the fix. However, we always recommend a proper diagnosis to rule out mechanical issues within the transmission itself.
What does “option M43” mean?
M43 is the Regular Production Option (RPO) code from GM that identifies the specific automatic transmission used in your vehicle. This TCM is specifically for IONs equipped with this transmission. You can find your vehicle’s RPO codes on a sticker, often located in the glove box or spare tire well.
Is any other setup required after installation?
No. Because this 2003-2004 Saturn ION TCM is programmed to your VIN, it is designed to be a plug-and-play installation. Once installed, you can reconnect the battery and your vehicle should operate correctly without any additional procedures.
