I looked through the forum and wasn't able to find a price on it. I heard that it makes your tranny shift quicker and prolongs the life of it. (I read that in http://forums.maxima.org/showthread.php?t=276224 this thread.) How much did you guys pay? I know it involves dropping the tranny pan and such but is it something I can do with a wrench a free day? Otherwise, how much to install? Thanks
