My Ford 2002 Ranger edge pick ups automatic transmission fails to shift gears under acceleration such as taking off from a light or merging on into traffic. The transmission will shift from one gear than not go into gear leaving vehicle on of gear and without forward motion. I have had problems getting across interceptions and onto the highway. Have to remove foot from accelerator for several seconds for transmission to find a gear to shift into. Ford motor company has some service bulletins regarding shifting issues but fall way short of correcting this safety issue. This has and is an on going issue since the vehicle was new.
