Abstract
Methods for modifying certain prior art automatic transmissions to strengthen the transmission and eliminate a tendency of the transmissions to fail as well as components for doing the same. Some aspects also include kits for modifying a transmission to increase the strength of the transmission. In some examples, the hydraulic system of a General Motor's model number 4L80E transmission is modified so that an overrun clutch is engaged in more modes of operation than the original equipment prior art 4L80E transmission in order to minimize a tendency for an overdrive roller clutch to fail.
