A transmission system includes a control system to control a fluid actuated clutch (16) and movable sheaves (68, 152). The clutch includes a deeply grooved pattern (345) to provide adequate cooling with low pressure oil before its return to sump and comprises a central disc with opposed surfaces (336), a resilient material layer affixed to each surface (341, 343) and a friction material layer (338, 340) affixed to each resilient layer. |
