I'm Awesome
I paid a guy to create me a little trans controller about 15 years ago for a 4L80E. It was setup to work with a steering wheel paddle shifter arrangement and it gave me manually operated up and down shifts at my fingertips. I think he charged me about $250, but this was back before the controllers became common and lower cost. It was in a twin turbo car that was a handful and being able to shift it with the paddles was very helpful!
