ABSTRACT:
The invention generally relates to the improved performance of the rear planetary gear in an automobile transmission. In particular, the invention relates to a new and improved thrust bearing assembly capable of sustaining performance of the rear planetary under more severe stress, and prolonging its life over much longer periods of time, than the OEM bearing. More particularly, the invention relates to a novel bearing assembly designed to replace the OEM bearings in the General Motors [GM] 4L60, 4L60E, and 700R4 transmissions which have a long history of rear planetary failures.
