I have a 2007 LS 2 out of a trailblazer backed to a 4L80E.....I am using the trailblazer ECM with a custom Howell wire harness. So the harness was built for the 4L80E and trailblazer combo and was told HP Tuners could change a download and make the combo work with out any issues. Now this is my first LS swap so i have been learning on the fly........HP Tuners says basically that combo wasn't a offered factory combo so ......they don't do that.

Now i have a buddy who is working on it and he says he thinks it can be done...as in someone will have a download for it. Short of that he says it can be done using relays....So if anyone has any great ideas please feel free to let me know
