    E40 computer OS swap?

    I'm doing a v8 swap with in a Colorado. I need to run an E40 computer to do it. I got a computer from the local junk yard but it's from a grandprix v6. Can I do a full write and put a trailblazer v8 OS on it? Also, is there a difference in the t42 TCM's? I also got it from a grandprix.

    I don't think those are actually E40's. They look just like them, and even use the same connectors...but they're not E40's and won't run E40 code.

    Im thinking the same thing, that service number is for an 04 Grand Prix and the E40 was only used from 05-06 on 5.3 and 6.0 V8s.
