Restore Crisp, Reliable Shifting to Your Saturn ION

If you’re dealing with the headaches of a failing transmission control module in your 2006-2007 Saturn ION—like harsh gear changes, getting stuck in limp mode, or a persistent check engine light—you’ve come to the right place. As a technician with over two decades of experience, I’ve seen countless GM vehicles sidelined by faulty TCMs. The T42 module, like this part number 24241806, is the electronic brain of your automatic transmission. When it fails, it can cause a cascade of frustrating and potentially damaging issues. This isn’t just a part; it’s a permanent solution designed to restore your vehicle’s original performance and reliability.

We take the guesswork and extra cost out of the repair. Each module is expertly programmed to your vehicle’s specific VIN before it ships. This means no expensive trips to the dealership for coding or flashing. It’s a true plug-and-play fix that a confident DIYer or any professional mechanic can install in under an hour. By replacing your faulty unit with this pre-programmed 2006-2007 ION TCM, you’re not just clearing codes; you’re addressing the root cause of the problem with a component built to meet or exceed original equipment standards.

Case Study: A Tricky Diagnosis

I once had a 2007 Saturn ION in my bay with a complaint of intermittent, violent downshifts when coming to a stop. The owner had already replaced two shift solenoids based on DTCs, but the problem persisted. A scan tool showed no active codes, but live data revealed erratic line pressure commands from the TCM. The internal circuitry was failing under load, but not consistently enough to set a hard fault. We installed one of our VIN-programmed T42 modules. The test drive was perfect—smooth shifts, predictable downshifts, and a happy customer who had been chasing this gremlin for months. This highlights why replacing the entire module is often the only definitive fix for these electronic issues.

Is Your Saturn ION Showing These Symptoms?

A failing TCM can manifest in several ways. If you’re experiencing any of the following, a faulty module is the likely culprit:

  • ✔ Harsh, slamming, or erratic shifting between gears.
  • ✔ The vehicle is stuck in one gear (often 2nd or 3rd), also known as “limp mode.”
  • ✔ Delayed engagement when shifting from Park to Drive or Reverse.
  • ✔ Check Engine Light or Transmission Warning Light is illuminated with codes like P0700, P0750, P0753, P0758, or other solenoid-related faults.
  • ✔ Poor fuel economy and a feeling of sluggish performance.
  • ✔ Complete loss of communication with the transmission module.

A Straightforward Guide to Installation

Installing your new 2006-2007 ION TCM is a simple process that you can do at home. For the Saturn ION, the module is typically found behind the driver-side strut tower in the engine compartment.

  1. Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
  2. Locate the Old TCM: Find the module behind the LH strut tower. It will have several large electrical connectors attached to it.
  3. Disconnect and Remove: Carefully unplug the wiring harnesses. They have locking tabs that may need to be pressed or lifted. Once disconnected, unbolt the module from its mounting bracket.
  4. Install the New Module: Bolt the new, pre-programmed module into place. Securely reconnect the wiring harnesses, making sure they click into place.
  5. Reconnect and Verify: Reconnect the negative battery terminal. Start the vehicle and check for any warning lights. While not always necessary, using a basic scan tool to clear any stored historical codes is a good final step.

Frequently Asked Questions

Do I need to have this module programmed by a dealer?

No. This is the biggest benefit we offer. We program the module to your vehicle’s VIN before shipping, so it’s ready for immediate installation right out of the box. This saves you hundreds of dollars and a trip to the dealership.

Is this part difficult to install myself?

For most DIYers with basic tools, this is a very manageable job. The TCM is located in the engine bay and is typically held on by a few bolts. The entire process usually takes less than 30 minutes.

What is a core charge?

A core charge is a deposit that is refunded when you send back your old part. We do not require a core charge for this module, so you can keep your old part without any hassle.

Will this fix a P0700 trouble code?

A P0700 code is a general fault request from the TCM to the main engine computer (ECM) to turn on the check engine light. This code almost always indicates a deeper problem within the transmission’s control system. If the root cause is a failing TCM, then yes, replacing it will resolve the P0700 code and the specific codes that triggered it.
