Transmission or something else?
I have a 2011 f150 4x4 sc 5.0 engine.Sometimes while driving at parking lot speed it seems the engine rpm stays up around 1000 while slowing to a stop and this causes a surge when you take back off.Anyone else noticed this?

As long as its not clunking really hard into to gear, or grinding any, I wouldn't worry about it.

At low speeds the trans can go to first gear if the speeds are low enough, thus causing higher rpm's and surging and rapid slowing down when letting off the gas. My 2010 does the same thing. First gear is so short (4.17:1), this would cause this if it doesn't shift to second gear at low speeds.
