Swap vss?

Maybe reach out to Hotwire Auto?

They have a tech article on the NAG-1 swap. I know it isn't the same, but in order to make that one work they add an ABS sensor, ABS module and the Front Control Module in order (I believe) to give the trans controller a speed signal. I wonder if you setup wouldn't require something similar.
