Thats the trouble with swapping transmissions from year to year is that they update/change them and then things like this happen.Engines will usually swap over fine, but trannies are a roll of the dice.If you still have the old trans, look at the amount/location of the pins at the connector and compare to the new trans to see if there are any differences
