"I wanted to give Edelbrock some of my money - they sell transmission controllers. I wrote to them and asked if they had a controller that worked for my transmission, and provided details. The first response was, basically, "email this other department within Edelbrock". Why couldn't they forward my request? Anyway, I emailed the other guys, and got this response:

TC #36212
It supports GM 4L60E, 4L70E, 4L75E, (up to 2010).

The response didn't answer my question. I'm not even sure if they meant that their controller would work or that it wouldn't. It did help me make a decision though!"
