Did someone here once say that over-tightening the drain plug on the bottom of the transmission can crack the casing along the seam? I used a breaker bar (for convenience only) and went "easy as it goes," but it kept going. I stopped at a point that seemed like 20 to 25 foot pounds of torque. I just wanted it snug relatively tight since I've seen it leak. I did use a pipe thread sealing tape (yellow). Am I at risk of harming that casing?
