In fact, contrary to common opinion, the rear planetary assembly in these transmissions is not, in any way, weak by design. This is a huge improvement and virtually eliminates one of the most common points of failure for this type of transmission. This allows oil to escape from between the bearing and the gear it rests against, feeding additional lube to the planetary gears. Next, the sun gear is inspected and modified to improve lubrication to the rear planetary assembly. In addition, dual bushings are installed in the rear sun gear to handle the extra weight of the beast sun shell.
At this time the center support and sprag (one way roller) are installed after being inspected for stress cracks and damage. The rear planetary assembly and bearings are meticulously inspected, then assembled into the case along with heavy duty reverse friction and steel plates. The seals in the case are then replaced and assembly begins. The case is specially prepared and a coating of and heavy duty, heat resistant, oil based enamel is baked on, creating a hard and durable glossy finish. The case and hard parts are cleaned thoroughly and re-inspected for cracks, wear, or other damage before we begin.
