About my 94 oldsmobile 88,the engine sounds good but there is no movement in all shifting, I heard a noise like a metal banging, I guest is the torque converter bolt is loosed,is it possible? I check the trans. oil, and the shifter fine,could you guide how to check for the converter bolt, thank"s

INBETWEEN THE ENGINE AND THE TRANNY YOU WILL SEE A METAL PLATE IN THE SHAPE OF A HALF MOON WITH 4-5 BOLTS HOLDING IT IN PLACE. SOME OF THESE YOU MAY HAVE TO REMOVE THE STARTER FOR, THE NOSE OF THE STARTER RUNS INTO THE TOP OF THE PLATE. AFTER THE PLATE IS REMOVED
YOU CAN BUY A SPECIAL TOOL TO TURN THE FLY WHEEL OR USE A FLAT SCREW DRIVER AND TURN THE FLY WHEEL A FEW TEETH AT A TIMETHE BOLTS SHOULD BE ON THE VERY BOTTOM OF THE FLY WHEEL BUT YOU MUST TURN THE FLY WHEEL TO GET TO ALL THE BOLTS ONE AT A TIME

Probs with torque converter are slim. It would still move unless converter broke completely loose. Check fluid level. Could be out
