I’ve been doing some maintenance work on my Duramax-powered truck and came across a bit of a puzzle. I need to locate the ground point for the Transmission Control Module (TCM), and I’m having trouble pinpointing it. Here are a few details:
Model: 2015 Chevrolet Silverado 2500HD
Engine: Duramax 6.6L V8
In my previous experiences, I’ve noticed that having a solid ground connection can vastly improve the performance and reliability of vehicle systems. I want to ensure that the TCM has a proper ground to avoid any issues down the line.
Questions:
Does anyone know the exact location of the TCM ground connection on this model?
Are there any tips for cleaning or securing the ground to prevent corrosion?
Should I expect any issues if the ground isn’t functioning properly?
I really appreciate any advice or direction someone can provide on this. Thanks in advance for your assistance!
The TCM ground is typically located near the transmission. It’s often bolted to the transmission case. Just make sure to check the harness for any breaks or corrosion too!
Has anyone noticed transmission slipping or erratic shifting? These might be signs of a TCM grounding issue. Grounding locations are crucial for reliable performance.
