want to adjust module on my 1966 289 C Code I know how it works but because of crossmember adjacent to module( not jacking car up) I can remove hose but cann't get angle with my screw driver.Trans shop who changed fluid and did some adjustments said hammer a wire coat hanger flat and use it bent as to turn screw.Sounds good in theory but did not work for me. Any ideas for a tool to use ? I can snake a long screw driver from front of cross member but maybe to big,as I cannot engage slot in module. Frustrating being right there and don't want to pay shop $35 for something so simple-Thanks in Advance--Doug
