Greetings friends I have the following problem with the transmission of a 2007 f150 FX4 super crew, it happens that when I'm on the road the truck does not take the over drive going 45 to 60 mph trembles a little, seems to have no power and does not exceed 75 mph when I try to accelerate to speed, only accelerates but does not feel that increase speed, as if it dont do the over dirve, just come down to third, appreciate any information, it seems that is the torque converter but I'm not sure, I appreciate your comments.
