never heard of black bear I will give them a call psi is who told me they couldn't make a harness for my 6.0 and my early 4l80e. they could only do it for the late model. they recommend I change to a late model trans.

how would the factory cpu change anything? according to psi you can't make that modern CPU run my trans. I'd still have a running motor but be wondering what I need to wire up from whats already there to the stock 6.0 harness to work the cpu already running the trans. I'd be in the same boat but out another grand in rounding up parts and tuning? for all that hassle I buy an 800 stand alone controller for the transI understood the question, I just don't know the answer. And felt the need to point out that with a factory 0411 setup instead of the FITech you wouldn't have these issues.
