The XT--1410--4 and XT--1410--5A Transmissions contain the following major components. They are keyed to Major Transmission Components. The transmission consists of: Torque Converter Housing. The torque converter housing is cast iron and is the front member of the transmis- sion. It has an engine flange at the front and its rear surfaces bolts to the transmission housing. It houses and supports the lockup clutch, torque converter, input--pump drive gears, and in--put--pressure and scavenge pumps. Its rear side supports the high--and intermediate--range clutches. Its top provides for mounting the oil filters, steer pressure--regulating valve, and the cooler bypass, lubrication and converter pressure--regulating valve, and the cooler bypass, lubrication, and converter pressure--regulator valve assembly. Transmission Housing. The transmission housing is cast iron. It houses and supports the range gearing, low-- and reverse--range clutches, output bevel gears, steer gears, and drive shaft. The transmission services both oil sump and oil reservoir. The oil sump is the area in which oil is maintained at the most efficient level for transmis- sion operation. The reservoir is an area separated from the sump and serving, as its name implies, to hold a res- ervoir of oil. The front of the housing provides the mounting surface for the torque converter housing. The top surface provides for mounting main and steer control valves and inspection and access cover. The side of the housing provide for mounting the right and left steer--clutch housing assemblies. Steer--Clutch Housing Assemblies. Each Steer--clutch consists of: Internal--Splined clutch plates Pressure Plate External--Splined clutch plates piston Drive Gear Piston Hub Clutch apply ring Housing Assembly NOTE XT--141--5A transmission output reduction gear assemblies do not contain sprocket studs. The housing mounts onto the sides of the transmission housing. The transmission housings also serve as a mounting for the output reduction--gear assemblies: Coupling assembly Internal--splined brake plates Sun gear External--splined brake plates Carrier assembly Brake movable cam ring assembly Ring gear Saddle Output shaft Brake housing Damper assembly Output reduction housing
