Hello there, I am Cam.
I am licensed automotive technician with more than 18 years experience.
As an expert on the site, I only have access to your question. Any billing questions or concerns would require a customer service specialist.
A couple things before we get going;
- I am around most days but not every minute of every day. If you reply while I am offline, I will respond when I am next online.
-I am a Firefighter/Paramedic which might require me to drop and run at any time without warning. If this happens, I will reply as soon as I am able to.
-The website will automatically offer a phone call. Some times they are beneficial, sometimes not.
I am sorry to hear you are having troubles with your vehicle. While I am looking at your question, can you tell me who I have the pleasure of assisting today?
You will need to change the transmission as well. The V6 has a 4 speed transmission where as the V8 has the 6 speed transmission. Plus the modules and controls are different between the 2, so trying to make it work could be harder that you think without changing everything.
Still not sure what you need?
Have a certified mobile mechanic diagnose what's wrong with your car, at your home or office.

I have 2 Chevy silverado trucks. One is a 2011 automatic v8 4x4. The other is a 2012 automatic v6 4x4. I want to put the v6 [engine](/topics-engine-chevy/) in my v8 truck. I know I must change the wiring harness and computer components. I need to know if I will have to change the transmissions. Will the v6 engine bolt up to the v8 transmission or will I need to switch them out?
