Restore Peak Transmission Performance in Your 2006-2007 Monte Carlo
Is your 2006 or 2007 Chevrolet Monte Carlo suffering from erratic shifting, getting stuck in gear, or displaying a check engine light? These are classic signs of a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every gear change and ensuring smooth, efficient operation. When it fails, it can lead to frustrating drivability issues, poor fuel economy, and potentially severe transmission damage if left unaddressed. This replacement GM T42 TCM, part number 24234274, is the definitive solution to restore your vehicle’s factory performance.
From the Diagnostic Bay
We recently had a 2007 Monte Carlo come into the shop with the owner convinced he needed a full transmission rebuild. The car was slamming into gear and would intermittently refuse to shift past 2nd. He had already spent hundreds replacing shift solenoids with no improvement. After a quick scan, we saw a cluster of communication and solenoid circuit codes pointing away from the solenoids themselves. We identified the root cause: an internally shorted TCM. Instead of a multi-thousand dollar rebuild, we installed a VIN-programmed T42 module. The customer was back on the road in under an hour with a perfectly shifting car, saving him a fortune and a massive headache. It’s a powerful reminder that diagnosing the electronics first is key.
Symptoms of a Failing Monte Carlo TCM
A faulty TCM can manifest in various ways. If you’re experiencing any of the following, it’s highly likely your transmission module is the culprit:
- ✔ Harsh, delayed, or unpredictable gear shifts.
- ✔ The vehicle feels stuck in one gear (often called “limp mode”).
- ✔ Your check engine light or transmission warning light is illuminated.
- ✔ Diagnostic trouble codes (DTCs) such as P0700, P0750, P0755, or other solenoid-related codes are present.
- ✔ A noticeable decrease in fuel efficiency.
- ✔ The transmission seems to slip out of gear or fails to engage properly from a stop.
- ✔ Inaccurate speedometer readings or other instrument cluster glitches.

Frequently Asked Questions
What is VIN programming and why is it necessary?
VIN programming is the process of loading your vehicle’s unique 17-digit Vehicle Identification Number and corresponding software onto the TCM. This is critical because it allows the module to communicate correctly with your car’s other computers, ensuring proper shift strategies, engine performance, and system integration. Our service handles this for you, making the part plug-and-play.
Will this TCM fix my specific transmission problem?
This module is designed to fix issues directly caused by a faulty TCM, such as erratic shifting, solenoid circuit codes (e.g., P0750-P0758), and communication errors (U-codes). While it resolves the most common electronic transmission faults, it cannot fix internal mechanical problems like worn clutches or a bad torque converter.
Is this a difficult part to install myself?
For most DIYers with basic tools, this is a straightforward installation. On the 2006-2007 Monte Carlo, the TCM is located in the lower air cleaner housing. The process involves disconnecting the battery, unplugging the electrical connectors, removing a few fasteners, and swapping the module. It typically takes less than an hour.
Do I need to send my old TCM back?
No, there is no core charge or requirement to return your old part. This simplifies the process for you and saves you money on core fees and return shipping.
What kind of warranty is included?
This Transmission Control Module comes with a one-year warranty, covering any defects in materials or workmanship. We stand behind the quality and reliability of our programmed electronics to give you peace of mind with your purchase.
