ZF fluid is Amber. And yes, it can cause your temp to fluctuate. And it is also important for the ZF box to be filled correctly. You might also have the wrong level in the trans, that can cook the oil, too low for instance.

Lots of variables here. two rebuilds and the thing is still messed up. I mean all your symptoms combined, sounds like your fluid is gone, your clutches are probably gone. Are you sure those that did the rebuild did it right, twice?
