went up to my brothers today and waxed the regal with the PC.
we also did a trans service on his Yukon, pan drop and filter, then we followed a write up on trans flushing for his truck, and it worked great. we took the top trans line off the radiator, screwed in a barbed fitting, then a clear tube. dumped 4 quarts in the trans, run it till you see small bubbles in the line, shut it off, add 4 more quarts, flush, and then one more time. it was easy, and no real mess to complain about either.
i see no reason why this would not work on our cars.
