my son did an adjustment on his automatic transmission on his 74 duster which has a 225. The one on the left hand side of his trannie. he backed it off then torqued it down to 41 pounds and oops, forgot to back it off 2 turns per the manuals instructions. Now it wont go into reverse, and if put in drive stalls the engine and the adjustment screw wont back off. Any easy fix for this problem and thanks in advance,
