Hi I have a 1999 F150 and I am having problems with the transmission. If overdrive is on it won’t go past 30 unless I keep constant pressure on the gas pedal and as soon as I let off it throws itself into neutral until I slow down to about 25. If I turn overdrive off I can drive and it’ll shift smooth for a bit but after a while it sticks until I get to about 25-30 and then it’ll shift. And if overdrive is off it won’t shift past 45. Anyone have any idea on what it could be? Thanks in advance
