Would transmission flush on a 97 tiborun with 170k mileage cause transmission leakage and eventual break down?
sadly in higher milage cars the auto tranny is in some cases being held together with the sludge and goo that the flush removes so by flushing it they removed what little hope your tranny had of lasting another 80 to 100 k same thing goes for motors flush them late in their life and its bad and new ones shouldnt need it at all proper maintnence and care is good enough
