Toyota installed gear driven transfer cases in 4 cylinder pickups and 4Runners from 1979 through 1995. Speed sensors were not used as standard equipment in these rigs until about 1992. Speed sensors from chain driven t-cases don't fit gear driven t-cases. This means that swapping out a chain driven case in favor of a gear driven unit, in a 1992 or newer Toyota, will require a speed sensor. Learn More
