Zusammenfassung:Transmissions with at least four gearing-arrangements and six clutches that produce nine forward speeds and one reverse. The gearing-arrangements may be simple planetary gearsets. The six clutches may include one to three brakes, and at least one clutch is an input clutch and one an output clutch. The input-shaft of each transmission may be associated with a carrier of one of the simple planetary gearsets. The input-shaft may be associated with carrier-1. The output-shaft of some transmissions may be associated with a carrier of another of the simple planetary gearsets. The output-shaft may be associated with carrier-4. Sun and ring gears in gearing-arrangements may be connected to a transmission housing. Sun-3 and ring-4 may be grounds.
