Lucas products never work for me go with another top brand trans medic. Also just draining the pan and replacing filter might not do it you also have to drain the the gear housing that holds several quarts of fluid in total it's 8 quarts you need to replace.

Putting in new fluid with that many miles does more harm than good. Try Lucas trans medic, hope for best.
