I am wanting to know the best option to control a GM 4L80E electronic transmission behind a 307 cu in V8 in a 71 Chevelle. My preference is to run with American made. I see there are a bunch of different options https://hgmelectronics.com/ , https://www.us-shift.com/ , https://www.msextra.com/. Do you have any thoughts into which one is the best in terms of quality and features?
