Dan is right in what he said , i've seen this problem many times due to bad connection at the harness down to the transmission , also seen many that have stuck open torque converter clutch solenoid valve , to check this you will have to remove transmission oil pan to test give battery voltage to solenoid valve you should hear a clicking sound if not replace valve
