I just changed the transmission fluid on my L275 tractor and I think I overfilled the transmission fluid by about 2 quarts. It seems to be past the viewing window, however when looking into the fill hole , the level seems to be about 4 to 5 inches below the top of transmission fill hole. The dealer said this is not a problem. Should I drain off about 2 quarts. The manual says it holds a little over 25 quarts and I think I have put in about 27.
