When I had my 64 409 4 speed Impala the pin in the case cover that the shifter forks worked on would come out. The almninum wouldn't hold a press fit. I would jack up the driver's side front wheel with the bumper jack and crawl under :eek: with a pair of plyers and a rachet. The trans oil didn't come out because the car was tipped to one side. I would feel down in the oil until I found the pin and pound it in with the back of the rachet and be back on the road in abut 20 minutes. By the way has anyone experienced this problem? I finally drilled a hole all the way through and bolted a stud to replace the pin. Roy
