how significant of a difference will changing the automatic tranny fluid make? how often should I be doing it? what about the gasket/filter kit? how often should I be doing that as well? also, will a tranny cooler really prolong the tranny life significantly, or just help a little? how hard is the install on the tranny cooler?
sorry for all the questions but it would REALLY help if I got all the answers/tips because my greatest fear is being stranded in the middle of a long long highway
also, what do you mean improve on what i'm replacing? such as getting a higher grade part? as in, you get what you pay for kinda mentality?
