ABSTRACT:
An automotive transmission mount has a top plate configured for attachment to a transmission housing, the top plate having a downwardly bent portion, the downwardly bent portion having a window formed therein; and also has a bottom plate configured for attachment to the cross-arm of a vehicle frame. The bottom plate has an upwardly extending portion having a flange formed thereon, the upwardly extending portion being received within the window of the downwardly bent portion such that the flange is captured by the downwardly bent portion. The top plate and the bottom plate thus interlock such that in the event of failure, the top plate and the bottom plate do not separate from one another. Polyurethane is molded intermediate the top plate and the bottom plate. An optional cover plate applies a preload to the polyurethane. The preload mitigates the need for adhesive bonding of the polyurethane to the top and bottom plates.
