I have a 1996 F150 V-8 automatic trans. with the over drive button blinking on and off. It will not shift into over drive. took it by Auto Zone and they did a scan on it, and the # PO 443 showed up. They didn't know what that meant. This truck only has 126073 original miles on it, and has always shifted without any problem. Also the fluid level is good, and there is no slipping.Please help. Thanks , Robert
