7. Next, Wood torqued down the center support bolts of the integrated valve body to 14 lb-ft in preparation for resurfacing. These bolts almost always work themselves loose over time, causing internal leakage and low ATF line pressure. Once tightened appropriately, Wood block-sanded the valve-body sealing surface. This resurfacing ensures the valve body will not leak once the transmission is rebuilt. Once perfect, the remaining internals of the transmission were removed from the case and the case was placed in a hot solvent bath.
