I have had a little dripping from my transmission, and was thinking about replacing the seal as thats where it looks like its coming from already checked and tightened every bolt for the pan and it still leaks a tiny bit. What im more worried about is if i replace the seal and put new transmission oil in will it make my transmission need to be rebuilt? Just wanted to see if its pretty common with our cars or not. I know a lot of the time if the fluid has never been changed sometimes its worse for the transmission because the detergents in the fluid that clean and sometimes the dirt and crap is whats holding it together. I have a 97GT Auto its around 110k miles..
