904 tranny questions

as was stated ,the bands were thin to begin with,but,there is away to do a shift kit n a mopar tranny,without buying one,and it will shift harder than it would,if u bought a shift kit to install in it.now the other question,is finding someone who know how to do it.my dads best friend,(ray kettles) r.i.p,could do it.and worked w him for yrs,but being young,dumb n full of spunk didnt pay alot of attention.sure there is other guys out there who can do it.
