Sorry dude !

Didn't you know that trans flush in high-mileage cars is nothing else but looking for trouble ?
All reputable mechanics after being asked for a tranny job the 1rst thing they do is
"ASK & VERIFY" the current mileage of the vehicule.
The mech knows about the risks a flush post to any vehicule close or over 100K with out proper maintainance records but he just didn't care at all.
