Not sure what tdrumm had, but I drive a G80 every day. I liked that the trutrac was consistent, I always knew how the rear tires were going to react when I hit the gas....with the G80 you never know what you're going to get. tdrumm also has an FLT trans (can't remember what level), which is extremely consistent. Seems like my trans and rear reacts differently every time I stab the gas, even under the same conditions.

 

You won't regret the truetrac. I put one in my 2000 reg. cab about a month ago,
so far nothing at all to complain about!
