Automatic Transaxle parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Gearbox Housing 1× Rigid cast housing that holds the gears and bearings in alignment, contains the lubricant, and mounts the gearbox to the machine.
2 Torque Converter 1× Fluid coupling multiplying torque at low speed.
3 Helical Gear Pair 9× Two meshing helical gears forming one reduction stage that steps torque up and speed down between parallel shafts with quiet, continuous tooth contact.
4 Valve Body 1× Hydraulic control block selecting gears.
5 Open Differential 4 parts 1× Open bevel-gear differential that splits drive torque between two wheels while letting them turn at different speeds in a corner.
6 Ball Bearing 6× Deep-groove radial ball bearing.
7 Oil Seal 4× Spring-loaded rotary lip seal that keeps lubricant inside a housing and dirt out where a shaft passes through, sized to DIN 3760.
