An improved system and method for disassembling the valve body assembly of a motor vehicle transmission. Air automatically ejects the internal components of a valve body assembly sub-assembly, thereby eliminating the need for an operator to manually "beat" the sub-assembly to remove said internal components. The process of separating the upper and lower sub-assembly, and of pre-washing the sub-assembly, remain the same as in the prior art. As before, the operator manually removes the valve retainers and plugs in each sub-assembly. The operator then loads either sub-assembly onto tooling specifically designed for that sub-assembly (either upper or lower). Once started, the tooling begins an automated, pre-programmed sequence of (1) clamping the sub-assembly, (2) injecting air into specific valve ports to eject internal components causing them to be automatically ejected into parts bins specified for each valve port, and (3) releasing the sub-assembly that no longer contains any internal parts.
