L31 & NV3500 4X4
What to do?? The (2002 Express Van) 411, OS 2156 PCM states it is a 4L80E, yet I would like to change it to a manual NV3500. The engine is a L31. I am utilizing TunerPro & OBDLink LX.
I have a .ctz file for the Mexican L31 & manual transmission, yet it seems to be no help since it is not in .bin format.
So, what can I do? Can the file be converted? Do have options?
