thanks all for the replies. sure didnt expect so many replies so quickly. i will be going to localy owned tranny shop tomorrow and talk to them to get some more input as they come very highly recomended by other family members. i actualy was thinking of a power purge so as to purge tranny and torgue converter of all the old fluid. i didnt state in original post but this truck only has 63000 miles and the fluid on dip stick looks very clean. i have owned it for a year now and it has come on slowly till just recently has become a major problem. all i use it for is a daily driver no towing or anything.
