My 1996 Sebring is stuck in limp mode I have changed the output speed sensor and the ETAX relay and fuse with no change so I'm going to change the TCM. What I need to know is I have seen several of them on line with the same part # as mine but out of different cars will they work in my Sebrink the part # is o4606359.
And will I need to have it reprogrammed.

Even if the replacement is the same part number it will likely needs security matched once installed.
Having said that, I wouldn't change another part that may or may not fix the problem until you have some idea what the problem actually is.
Rather than spray your car with parts and hope something eventually fixes the fault, spend some of that hard earned money on a proper diagnosis.
Spend a little to find out what is wrong and change just that part.
