I have a 2005 F150 5.4L Triton. Recently, started stalling when I shift from Drive to Reverse..only happend 4 times so far. Also, coincidence or not, I don't know, but my speed/volume control module for my stereo has started acting up (i.e. radio voluming turning right down while slowing,braking and it's not due to a radio setting). Oil is fine, need to check tranny fluid, but any ideas???

 

Low trans fluid can do this.
