I'd take the conservative route and do a series of drain and refills. Too many horror stories of people taking in a high-mileage vehicle with zero problems for a transmission flush only to come out with transmission issues.As the title states, my 04 Titan has not had a good trans flush in, well, ever...... Running fine and not slipping so
Do I leave alone
Do I do a poor man's drain/replce
or do I bite the bullet and dive in for a full flush?
Thoughts? I am leaning towards it ain't broke don't touch but would like to hear from those in the know
