TCI Maximizer Rebuild Kits
TCI Maximizer rebuild kits are ideally suited for off-road, towing, and other severe-duty applications. Each kit contains gaskets, seals, new premium-quality frictions, steels, a high-volume filter, and a drain plug. Also included are valve body recalibration modifications, which provide crisper shifts without the harsh feel found in kits designed for racing. Durability is improved because less heat is generated per shift than is associated with the OEM shift characteristics. TCI Maximizer rebuild kits also increase the torque capacity of the transmission to make towing or off-roading a breeze.
