So here's the story. I have a 2010 Camaro SS that I had a shop do a 4l80E swap. Here's the issue when you turn the key off the car still runs for about 4-5 seconds. WTF is going on? Where do I start trying to figure this out.

I recommend taking the car back to the shop.

That's not even an option at this point.

To help we would likely need to know exactly what changes were made electrically, e.g. to the harness and what tuning changes were made. Do you know if the shop used a known "kit" ?
I assume you don't have tuning software.

Also, since this is mostly a Gen-4 forum and not specifically a Gen-5 forum, only a small percentage of members know much about Gen-5 cars.

Here is what the did electrically.

one thing that is different is that the tps signal is coming from pedal not the ecm.

As far as tunning changes... I was told the turned of a tranny codes being that I had a manual 6speed. I have both HP tuner and PCS trans controller software.
