Automatic Transmission - 4L60E question

My friend has 94 z28 and his a4 is slipping, he recently bought a a4 trany out of a 94 Trans Am and it has the performance shift button. He needs to know if it will work or if he needs to do something to the computer?

If his pcm doesn't have the dual setting, his tranny won't be receiving any input except the stock input. No need to modify the trans. Just bolt it up and go.

Thanks Patrick
