As far as i have been able to find out they are both 4T80E 3.71 Gearing Ratios as they are both VIN code '9' but according to the Hollander Interchange Guide they are not compatible or at least not directly interchangeable, they should be the same as they are both 4T80E and the same gearing correct? Hoping that this can work out as the 97 is kind of beat up looking, the 2002 is in perfect condition other than the transmission needing replacement.

Anyway hope that someone can help with this query as I and my mechanic arent 100% on this...

I wouldn't use him if he is not familiar enough... something like this and there's sure to be issues.

I really don't know, but I think I'd put money on it not being feasible. 97 and 02 are totally different animals.

If they are both STS's, then they are the same transmissions. I am not positive, but I would bet they are interchangeable.
