Hey guys, I'm going to do the amsoil transmission flush this weekend on my 4rnr but with mobil 1 syn atf (since it was easily avail). I also saw lubegard at oreilly's and was wandering which one would be better to get, the red or black bottle? I will mention that I tow a 2000 lb. boat on occasion (I am getting a tranny cooler soon) so is either one a better choice? Or does anyone recommend any other tranny additives? My rig has over 154k miles on it, so I'm trying to keep the tranny in top shape, I have only done drain and fills previously. Any advice is greatly appreciated.
