Yes it should. I went from a turbo 350 auto 3spd to a 4L60 auto 4spd, had no issues at all. Just make sure the shifter is in park and the trans shift shaft is in park when you hook the linkages up, that way park is park, reverse is reverse and so on. It wouldn't be good if your shifter was in park and your shift shaft was in neutral or some other gear, when you shifted you would always be in the wrong gear. Just make sure both are in park before hooking the linkage up, the linkage can be adjusted also if needed to make solid, positive shifts into each gear if you think it's not fully engaging or has slop or play.
