I have a 94 z28 and the 3 and 4 went out. I found and bought a 93 trans out of a z28 with 30,000 miles on it. Just found out that they r not the same. is it possible to put the electronic shift from the newer one into the older one? i havent removed the 94 tranny yet. Am also cosidering pulling all guts out of the older one and installing in the newr one but am looking for easiest route.
