ABSTRACT:
A transmission mounting system includes a plurality of adjustable support units which are positioned between a transmission and supporting or reference surfaces. Each support unit includes a relatively yieldable elastic bearing and an extensible-retractible spacing link arranged in tandem. Signals indicative of the distance between transmission and the support surface are generated by a sensor and received by a control unit. The control unit effects dimension changes in the spacing link which compensate for deformation of the elastic bearing.
