2006 Ford E450 Transmission issue

Traveling over the Rocky Mts in 100 degree heat the transmission fan ran occasionally. After a stop for lunch the transmission ran when we started up and went into limp mode when we tried to accelerate onto the freeway. It recovered but acted strange for a bit. The next day we had it serviced, flushed, new fluids. Seemed to work ok. On the way home we noticed after a long pull it made a Shhhhhh sound that would get louder, but stop when you let off of the gas. If we stopped for a short time everything worked ok. Noticed that the transmission fan never came on anymore.

Anyone had this sort of problem? I think maybe the temperature sensor is bad.

    Taken from mechanic on Ford truck forum:
    Might be worth considering.

    Ok here is what you need to do the wrench light is coming on due to either a trans malfunction or a throttle body malfuntion. You need to take to ford dealer and have the codes ran to determine what codes you have. If the throttle position sensor that is built in the throttle body is intermittenly acting up that will cause your problem. Also there is a oss sensor (output speed shaft) that is internal to trans where the valve body mounts that has given us some problems as well but after you have the codes read we will have a better understanding of what is going on and which system is causing your problem let me know what you have so we can get to the bottom of the problem.Hope this information helps thanks
