Abstract
A replacement shift knob assembly for use on a truck transmission. Many truck transmissions have shift knob assemblies that contain a removable knob element with a specific bottom configuration and at least one manual switch that relies upon the specific bottom configuration of the knob element to function. The present invention replacement shift knob assembly includes a knob element made from an aesthetically pleasing material such as wood, stone, ceramic of the like. A base plate is attached to the bottom of the knob element. The base plate has a first side and an opposite second side, wherein the second side of the base plate is configured to generally physically mimic the specific bottom configuration of the original shift knob being replaced. The base plate is made from a material that differs from the replacement knob element in order to provide the base plate with greater material strength and wear resistance. As a result, a replacement shift knob assembly is provided that is aesthetically pleasing yet contains the same strength and functional elements as does the original knob element that is being replaced.
