TH400 Rear Case Bearing

The TCI TH400 Rear Case Bearing is a precision roller-type thrust bearing assembly specifically designed for Turbo 400 transmissions. This essential component helps manage end-play at the rear of the transmission case, which is crucial for preventing crankshaft walk and ensuring proper alignment under load. It is ideal for transmission rebuilders, performance shops, and serious DIY enthusiasts.

This bearing kit includes three selectable steel washers with thicknesses of 0.010, 0.015, and 0.020 inches, allowing technicians to achieve precise clearance specifications during rebuilds or diagnostics. The TCI bearing is engineered to withstand harsh environments, including constant radial loads, temperature fluctuations, and exposure to transmission fluid. Its steel roller construction offers superior wear resistance compared to softer materials, enhancing durability and extending service life.

With the included washer options, builders can easily match OEM specifications or compensate for wear on mating surfaces, minimizing the need for multiple kits during a single rebuild. Proper selection and adjustment of the rear case bearing are vital to prevent transmission failure, especially in high-torque applications or aggressive shift programming. This TCI 224400 kit is a must-have for anyone working on TH400 units in street, strip, or towing scenarios.
