1 of 2 things Happened 1 Whoever worked on it Disconnected the "VACUUM HOSE" to the "VACUUM MODUELATOR" This Unit is Located at the Side of the Transmission about 2/3 way back Driver side I Believe -- if not Passenger Side. Has useualy a Steal Line that runs from BEHIND Carb Leading down to the trans. Vacuum Moduelator helps Control the Shiftpoints
\015\012and without it it will ONLY SHIFT MANUALY. Hoping this is Good Info for you and you get it Corrected Please DONT FORGET TO RATE ME thanx RejakWilson
