ABSTRACT:
Increased resistance to excessive wear rate is provided in certain automobile automatic transmissions by providing a combination thrust-washer/radial-bushing at a certain position on the oil pump stator where the customarily manufactured transmission is provided only with a thrust-washer. The combination thrust-washer/radial-bushing provides bearing surfaces for the direct clutch drum to revolve against in both the lateral and radial directions. A reamer tool designed specifically for modifying the rotor portion of the direct clutch drum is disclosed.
