Take a look at the underside of a 204, 205 or 212 transmission.
One point that I forgot to bring out is the vertical movement of the transmission due to the two per rev. The amount of vertical movement is dependent upon the wear on the transmission mounts. When the transmission moves upwards there is a tension load applied to the lift link. This will cause the transmission to move in relation to the lift link connection point. When the transmission moves downward there is a compressive load applied to the lift link and the same thing will occur but in the opposite direction.
I have this phenomenon diagrammed out but the diagram is made using a program called Visio and can not be sent via e-mail unless the recipient has that same program.
