Whatcha think guys....my 04 Rainer is due for the 30,000 miles treatment from the dealer...one of the items is a 'tranny flush'. I am uncomfortable with this...as I feel dropping the pan and a new filter would be more suitable. Any thouughts would be appreciated. <img src="http://forums.aaca.org/images/graemlins/confused.gif" alt="" />
