To start Ive already had the OD problem where the car just revs but doesnt pull when OD is on.. when off it drives normally.. I remember someone saying it could just be a broken pin but its not worth the change if you havent replaced the fluid.. it could screw up the tranny.. So i left it..

Now I have some whining noise pretty constant through out all gears, at high speeds its still there only faint because of higher engine and wind noise.

Im still not 100% sure its the tranny, but this morning I got a transmission failure light come on and the OD light kept flashing.

so thats now 3 potential problems.. however she still runs fine and pulls normal.. its just annoying as hell.

its an 05 F150 with 404K +
