What does a transmission relay switch do?

I put in a transmission from a Dodge Stratus into my Chrysler Cirrus and my mechanic crossed some wires and burnt the starter. I got a new starter and it started again, but the radiator fan keeps running really hard and the alternator light is on now. The transmission doesn’t go into gear, and when it does it just goes into gear and back out in a matter of 3 seconds. We’re going to check if the alternator is bad, but I need some other suggestions on what might be wrong, and if the relay switch or TCM might need to be changed. I need a lot of help on this one. Thanks.
