Sonnax Smart-Tech Input Housing Kits

Sonnax Smart-Tech input housing kits address the weak areas of 4-speed automatic transmissions. Flexing and bowing of OEM and other aftermarket backing plates is eliminated with Sonnax's heavy-duty bolt-on anchoring plates. Their unique design ensures even clamping of the 3-4 clutches in higher horsepower, higher pressure applications. By eliminating the 3-4 snap ring and using a thinner, yet stiffer apply plate, space is made available for additional frictions and steels. This makes it possible to simultaneously increase clutch torque capacity and eliminate the possibility of retaining ring blow-out. A steel reinforcement sleeve prevents breakage in the spline area. Housing fatigue/failure-resistance and housing life are significantly improved with a special treatment process that greatly reduces stress crack formation.
