37477-41 45CI Transmission Race Thrust Washer

Proper end-play and spacing are vital for the health of any vintage gearbox. This transmission race thrust washer from Samwel Supplies is designed for 45CI Flathead and Servi-Car models, fitting transmissions from 1932 through 1974. It is a direct replacement for OEM 37477-41 and is essential for maintaining the correct alignment of internal components. Over decades of use, original washers can thin or become scored, leading to excessive movement and premature wear of gears and shafts. Installing this high-quality thrust washer during a rebuild ensures that your transmission is shimmed correctly, providing smoother operation and protecting your hard-to-find internal parts from unnecessary damage.
