Changing transmission out in 97 k1500 to newer 4l60e need to know compatibility?

What is your question?

Can I take a 98 or an 08 not sure the year. Numbers on transmission are 8KCD 4l60e six bolt transmission and transfer case and put it in a 97 gmc with with a four bolt to six bolt spacer by just buying the six bolt adaptor? I do have the newer transfer case but it has 5 plugs on it where mine only has 2 plugs. How would I go about gettin this in my truck?

What makes this problem better or worse?

mine is a six blot to four and the newer is six to six

How long has your 1997 GMC C1500 had this problem?

few months
