ZR-1 Net Registry Forums - View Single Post - SEVERAL ZF 6x ---> auto conversions??? Any on the boards here?

I recall that one of the first AT ZR-1 conversions was done by a fellow named Mark Weaver. He was an engineer with GM and had access to inside information at GM. I think it was 4L60E. He had a one of a kind truck transmission controller for the transmission. I made an effort to find out how to reprogram the shift points but never could find a bit of information about the controller or Mark Weaver.

The car was a red 1990. It was nicely documented by a Detroit newspaper. The newspaper article was in the car. I recently heard that it was for sale in Idaho.
