Need some help!
 

I'm new here but have been reading a little about the sebring because my girlfriends car went into limp mode so I picked up a new speed sensor. My question is... where the heck is this thing? I've been laying on the ground and up in the engine bay for over an hour looking for it!

Front of the transmission. You can get to the input and output speed sensors from on top. Remove the air cleaner box. Other things can cause the transmission to go into limp mode. How's the fluid?
