Overview

TCI Maximizer Transmission Kits are transmission overhaul kits that are ideally suited for off-road, towing and other severe-duty applications. Kits cover most of the popular automatic transmissions found in light and medium duty applications. Each kit contains gaskets, seals, premium-quality frictions, steels, a high volume filter and even a drain plug kit. Also included is a Valve Body Performance Improvement Kit that delivers a good, solid shift suitable for towing applications. Valve body recalibration modifications provide "crisper" shifts without the "harsh" feel that you often find in kits designed for racing. Durability is improved, as there is less heat generated per shift than is associated with OEM shift characteristics. The Maximizer Kits also increase the torque capacity of transmissions to make towing or off-roading a breeze. This Maximizer Transmission Service Kit for 93-98 4L60E transmissions includes the gaskets, seals, frictions, steels and a valve body kit for crisper shifts and improved driving characteristics in your 4x4 or towing application.
