ok, my crossfire went into limp mode ( stuck in 2nd gear and will not shift) two weeks ago and i took it to a friend's shop that scanned and said my speed sensor gave out (didnt specify which one)....so i took it to the dealership where they diagnosed it and foud that my transmission cooler lines were bent, they said the tranny fluid was not sufficiently being passed....i'm not very familiar with mechanical operations, therefore i need ur advice...can tranny fluid cause the car's transmission to be stuck in 2nd, or is it the speed sensor...or do i really need both....my warranty expired....

 

My question is how did the cooling lines get bent? I think either one of the problems would cause it to go into limp mode to protect the tranny from damage.
