Disassembly/Reassembly
1.
If a valve is restricted by a metal burr from machining that bore remove the valve and burr then inspect movement in the valve's normal position. If
no other debris or restrictions are found reassemble the valve body and install in the transmission.
2.
If the valve body has been contaminated with debris from another transmission component failure disassemble all bores for complete cleaning of
all valve body components. If possible keep individual bore parts separated for ease of reassembly. Use the following illustrations in this bulletin
for a positive identification and location of individual parts:

Caution:
Use appropriate eye protection when cleaning the valve body to prevent injury.
3.
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.
4.
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.
