tranny issue

[alhacker]

hi everyone i have the weirdest thing going on in my ride sometimes the kickdown works sometimes it doesn't and sometimes when i start the car i hear a bang which i suspect its from the tranny.... i went to 3 different mechanincs no one seems to find the problem there is no error codes and all the wiring is fine any suggestions?? but all of them seem they want to rip out the tranny to see if there is a problem.... its the 5sp auto tranny

It may be going out, just pay close attention to shifts and any very odd behavior.
