Final drive is 4.44 on the 97-98 T/TB's and S/TB's - I have the same transmission (that 98 with that code) that you are talking about. The gear ratios are also different from the 98 transmission to the 2000 one you bought. I don't know the final drive ratio on the 2000 one you bought.
Unfortunately that's all I can 100% tell you.
Oh, and yes, there is literally no information on the transmission any where.
PS - You should sell the 2000 and by my 97. That parts car you purchased is identical to my car and is completely different than the 2000 you have (different engine, trans, axles, diffs)
