The 6R80 has been tested to 150,000 equivalent miles in testing cycles that reflect the most extreme-use customer, and the box itself is rated up to 7,000 rpm. The fluid is filled for life.
150,000 miles is the MOST EXTREME-USE CUSTOMER? I have 239k on my Sport Trac. I had 283k on my GMC when I sold it. I had 240k on the Contour, 220k on a Celica, etc., etc.
I wonder what they would call me if 150k is the most extreme-use customer?
As I read that, it means the testing cycles used were supposed to emulate extreme customer use, and they ran the test for 150,000 miles. Not that the 150,000 miles represent extreme use.
Of course, they didn't describe what the cycles actually did.
