An automotive transmission mount, comprising:

• a top bracket configured to be attachable to a tail shaft of a transmission housing, the top bracket being T-shaped and comprising a top plate portion and a vertical plate portion extending laterally outwardly from the top plate portion, the vertical plate portion includes a circular opening formed therewithin;
• a bottom bracket configured to be attachable to a cross member of a vehicle frame, the bottom bracket being U-shaped and comprising a horizontal web and a pair of spaced vertical webs extending laterally outwardly from the horizontal web and having a cylindrical locking pin extending between the pair of vertical webs, the locking pin being disposed in spaced parallel relation to the horizontal web and passing through a center of the opening to interlock the top bracket to the bottom bracket, the bottom bracket being pivotable and translatable relative to the top bracket;
• a polyurethane material overmolding the top and bottom brackets;
• and
• a lateral relief hole extending through the polyurethane material and being oriented parallel to the top bracket, the lateral relief hole being adapted to deform during compression of the polyurethane material as a result of relative movement of the top bracket toward the bottom bracket such that shearing of the polyurethane material is prevented.
