I have a 96 f150 4.9 2 wheel drive automatic xl. A couple months ago truck started banging into gear. I would reset it by disconnecting the battery. Now it does it all the time. Got codes read and it camee up as po500. Vehicle speed sensor. Changed the speed sensor. Now the speedometer is going crazy on top of banging into gear, overdrive light is on and check engine light is on but you can reset that. Does anyone know what I should do from here.thanks for your help.
