ABSTRACT:
The present invention details a sleeve and bushing of an electromechanical automatic planetary transmission. The sleeve and bushing operate to confine the desired flow of transmission lubricant through the components of the planetary gear arrangement. Additionally, the sleeve and bushing assist in maintaining a sufficient pressure level in the cavity of the planetary carrier to enable the lubricant to reach the bearings of the pinion gear. Moreover, the radius or size of the bushing/sleeve arrangement can be adjusted to occupy the radial clearance or cavity between the sun gear and main shaft for an automatic transmission with axially separable splined sun gear and sun gear shaft.
