A/T - AOD Relief Valves For Valve Bodies
TSB 87-29 (May)FORD AOD
SUBJECT: Relief valves for AOD valve bodies
Note
On the earlier valve bodies ('80-'81) both relief valves are the same. On the later ones, the converter relief valve has a longer stem.
Part number E2AZ7E217-A is the converter relief valve with a long stem.
This should be installed on the earlier valve bodies to help prevent it from "buzzing".
