Is Your Express Van Sidelined by Transmission Problems?
For a business owner or contractor, a Chevrolet Express 2500 that won’t shift correctly isn’t just an inconvenience—it’s a direct hit to your bottom line. Unpredictable shifting, getting stuck in gear, or a lit check engine light means downtime, delayed jobs, and lost revenue. Get your workhorse back on the road and running reliably with our pre-programmed T42 Transmission Control Module (TCM), the definitive solution for restoring your van’s performance and your peace of mind.
Common Symptoms & Your Solution
A failing TCM can manifest in several ways, often making you think the entire transmission is failing. Before considering a costly transmission replacement, check if you’re experiencing these classic signs of a bad module. This unit is specifically designed to resolve them.
- Harsh & Erratic Shifting: Abrupt, jerky gear changes or a feeling of the transmission slipping between gears.
- Delayed Engagement: A noticeable lag when shifting from Park into Drive or Reverse.
- Limp Mode: The van is stuck in a single gear (usually 2nd or 3rd) with drastically reduced power, a safety feature triggered by the faulty module.
- Warning Lights: A persistent Check Engine Light or Transmission Warning Light on your dash.
- Diagnostic Trouble Codes (DTCs): Your mechanic pulls codes like P0700 (Transmission Control System Malfunction), P0750-P0758 (Shift Solenoid Errors), or other transmission-related faults.
This plug-and-play Express 2500 24243901 transmission control module is the direct fix for these issues, restoring the crisp, logical shifting your vehicle had from the factory.

Expert Insight: The Power of Pre-Programming
For a work van like the Express 2500, every hour off the road is money lost. That’s why VIN programming is not just a feature; it’s a critical benefit.

The module arrives at your door ready to install. You simply swap the part, reconnect the battery, and you’re back in business. It’s the fastest, most cost-effective way to get your van running right.
By installing our expertly prepared Express 2500 24243901 transmission control module, you’re not just buying a part; you’re investing in the reliability and uptime of your most important business tool. Don’t let a small electronic component sideline your entire operation.
Frequently Asked Questions
What does a Transmission Control Module (TCM) actually do?
The TCM is the ‘brain’ of your automatic transmission. It receives data from various sensors on the engine and vehicle, then uses that information to control exactly when and how the transmission shifts gears, ensuring optimal performance, fuel economy, and smoothness.
Is this module truly ‘plug-and-play’?
Yes. Because we program it to your vehicle’s specific VIN before shipping, it is ready for immediate installation and operation. No further programming or dealer visits are required. Simply install the part, reconnect your battery, and clear any old codes with a basic scan tool.
How do I know for sure that my TCM is the problem?
While the symptoms listed above are strong indicators, the most definitive way is through a proper diagnosis with a professional scan tool. Common fault codes like P0700, along with specific solenoid codes, almost always point to a failing TCM, especially when the shifting problems are erratic or electronic in nature.
Where is the TCM located on my Express van?
On the 2006-2014 Savana and Express vans, the TCM is typically located in the engine compartment on the right-hand (passenger) side. Always disconnect the vehicle’s battery before starting the replacement process.
Do I need to send my old part back (core charge)?
No, there is no core charge for this Express 2500 24243901 transmission control module. You can keep your old part, which saves you the time and hassle of return shipping.
