The above answer is right. But the problem is that you will have to change the 97 computer,fuel pump, Engine and transmission wireing harness. You will also have to put the 700R4 transmission in that 97 Tahoe. Reason being is that the 91 computer that you HAVE to use won't shift the 4L60E that's in the Tahoe now.
