My 4r70w is acting up and im baffled on what the problem could be. It started out where, when i drive in D, my first gear felt a bit sluggish, and by the time she shifted to 2nd she was ok, all other gears are fine as well. Then i noticed when putting the car in manual 1st, the car wouldnt move, i could even try to push the car physically from behind and it wouldnt move, it was as if something was physically holding the car back. I ended up unplugging the connections from the transmission to see what would happen, the transmission goes into limp mode and stays in 2nd gear, all the problems go away. I replug the connector back and test drive again, this time my 1st gear didnt seem to hold the car back *as much*. I thought i was getting some improvment, THEN, my reverse started to slip. Now im not quite sure what to think. My CEL isnt on, just the ford wrench malfunctioning light, but my scan tool doesnt pick a code out. Also my O/D light isnt flashing or anything!
HELP!

 

sounds like a huge problem
