Abstract: A transmission-mount assembly includes a transmission-mounting bracket and a frame-mounting bracket. The frame-mounting bracket includes a pair of sidewalls and the transmission-mounting bracket includes a tube, where the transmission-mounting bracket is coupled to the frame-mounting bracket with the tube arranged between the sidewalls. A bolt may be inserted through channels configured in the sidewalls and a bore of the tube to couple the transmission-mounting bracket within the frame-mounting bracket. The channels may include one or more features to inhibit misalignment and facilitate establishment of a positive lock between the transmission-mounting bracket and the frame-mounting bracket.
