I have an 02 Ranger with an automatic transmission. At normal driving, it shifts OK. But, if I need speed, fast, it feels like it is hung in 1st gear until I let off the accelerator. Then it shifts good throughout the rest of the gears. Since the tranny feels strong and don't slip, I would think it is something simple like the speed sensor or maybe something a little harder to get to, like a shift solinoid. Anyone had this problem before? And if so, what component did you eventually replace that solved the problem? Also, anyone got a printed breakdown of this tranny? I need to get this fixed before my Wife blows up the engine.
Any thoughts would be greatly appreciated.
