Put a 1990 s10 4.3l engine and 700r4 transmission in a 1988 s10 that had a 2.8l (blown) and 700r4 transmission. The 1988 had a mechanical cable for the speed sensor and the 4.3 has an electronic sensor. What needs to change in the 1988 to make it work with the 1990 transmission? The VSS hookup is the same. Took over the outfeed shaft housing and the shaft sprockets are completely different and will not interchange. Can't use the 2.8l transmission because of the 60° vs. 90° housings. Any help would be appreciated.
