Common Symptoms & Your Solution
A faulty TCM can cause a host of frustrating and debilitating issues for your vehicle. If you’re experiencing any of the following, this module is designed to be the direct fix:
- Harsh or Delayed Shifting: Abrupt gear changes, banging into gear, or a noticeable delay when shifting from park to drive or reverse.
- Stuck in “Limp Mode”: The transmission refuses to shift, often getting stuck in 2nd or 3rd gear to prevent further damage.
- Warning Lights: An illuminated Check Engine Light or Transmission Warning Light on your dashboard.
- Diagnostic Trouble Codes (DTCs): Common codes like P0700 (Transmission Control System Malfunction) or various solenoid-specific codes (e.g., P0750-P0758) point directly to a control system failure.
- Poor Performance & Fuel Economy: Inconsistent shifting leads to inefficient engine operation and a noticeable drop in gas mileage.
By replacing your old unit with this pre-programmed 2006-2014 Savana 2500 transmission control module, you directly address the electronic source of these problems, restoring the precise, factory-intended operation of your automatic transmission.

Frequently Asked Questions
What does VIN programming mean for me?
VIN programming means we load your vehicle’s unique Vehicle Identification Number and the latest GM software onto the module before we ship it. This makes the module a true plug-and-play part, as it’s already configured to work with your Savana’s specific engine, transmission, and options. It completely eliminates the need for a trip to the dealer for programming.
Is this a difficult part to install?
For someone with basic mechanical skills, installation is straightforward. The TCM is typically located in the engine compartment (on the RH side for the Savana). The process involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in reverse order. Most installations take less than 30 minutes.
Will this TCM fix a P0700 trouble code?
A P0700 code is a general code indicating that the TCM has detected a fault. Often, the root cause is the TCM itself. Replacing a failing module with this pre-programmed unit is a very common and effective way to resolve a P0700 code and any related solenoid codes.
Do I need to send my old part back?
No. This module is sold without a core charge. You can keep, recycle, or dispose of your old part at your convenience, saving you the hassle and expense of return shipping.
How do I know for sure that my TCM is the problem?
While the symptoms listed are strong indicators, a definitive diagnosis from a professional mechanic or a high-quality scan tool is always the best practice. Common signs include communication errors with the TCM, multiple solenoid circuit codes, and erratic behavior that isn’t tied to a mechanical failure.
