  6. Schematic, Geartrain Long Pinion Ring Gear Carrier Short Pinion Front/Large Sun Gear Rear/Small Sun Gear A simplified view of the geartrain. Tom Birch, 8/06

  7. Schematic, Control Devices Front/Intermediate One-Way Rear/Low-Rev. Band Clutch Band High-Reverse Clutch Front/Forward Clutch Tom Birch, 8/06

  8. First Gear Carrier is Held Small Sun Gear is Driven With the carrier held from rotating and the small sun gear is driven, the pinion gears become idler gears. Input Reaction Output Tom Birch, 8/06

  9. Schematic, 1st Gear One-Way Clutch Holding Forward Clutch Applied Gear Ratio, 2.4:1 The rear band is applied in manual 1. Input Reaction Output Tom Birch, 8/06

  10. Second Gear Large sun gear is Held Small Sun Gear is Driven When the large sun gear is held from rotating and the small sun gear is driven, the long pinion gears must walk around the sun gear. Input Reaction Output Tom Birch, 8/06

  11. Schematic, 2nd Gear Front Band Holding Forward Clutch Applied Gear Ratio, 1.5:1 Input Reaction Output Tom Birch, 8/06

  12. Third/High Gear Large Sun Gear is Driven Small Sun Gear is Driven When both sun gears are driven, the pinion gears will lock and produce a 1:1 ratio. Input Reaction Output Tom Birch, 8/06

  13. Schematic, 3rd Gear High-Reverse Clutch Applied High-Reverse Clutch Applied Forward Clutch Applied Gear Ratio, 1:1 Input Reaction Output Tom Birch, 8/06

  14. Reverse Large Sun Gear is Driven Carrier is Held When the carrier is held from rotating and the large sun gear is driven, the long pinion gears become idler gears. Input Reaction Output Tom Birch, 8/06

  15. Schematic, Reverse High-Reverse Clutch Applied Rear Band Holding Gear Ratio, 1.8:1 Input Reaction Output Tom Birch, 8/06

  16. Variation, 3L30 Input Shaft Clutch Drum Input Sun Gear 3rd Clutch Input Sprag Carrier/Output Ring Gear Band Reaction Sun Shaft Gear Note that the output shaft is combined with the carrier. Tom Birch, 8/06
