Does the Ontario Drive Clean put unreasonable stress on the vehicle's
transmission?

For the second time, one of our cars has blown a transmission during
or immediately after the test. The first was our 4WD AeroStar back in
the first year of the program was in place. They had the van on the
test rack and were reving it for what seemed like 10 minutes -  I was
there and asked them why and they said they had to do that for a AWD
vehicle. Sure enough, suddenly the floor is covered with tranny fluid.
Coincidence, they said, it must have been ready to fail.

Now, my mother, the typical Sunday driver, with her 7 year old Ford
Taurus with 35,000 Miles on it, gets a passing grade yesterday
afternoon then drives it the 2 miles home and parkes it in the garage.
This morning she can't get the car in gear and the garage floor is
covered in transmission fluid. Coincidence again?
