If the valve body has been contaminated with debris from another transmission component failure then disassemble all bores for complete cleaning of all
valve body components. Keeping individual bore parts separated will make reassembly easier. Use the illustrations for positive identification and
location of individual parts.
Using GM Brake Clean or equivalent in a safe and clean environment (clean aluminum pan) clean the valve body and dry it with compressed air. Use
appropriate eye protection.
Clean individual valve body components with GM Brake Clean or equivalent. Coat each valve with clean ATF and reassemble in each bore. Check each
valve for free movement during assembly of each bore.
Position the valve body as shown in the illustrations for positive identification and location of individual parts.
