In defense of the transmissions of Tauruses (Tauri?), please allow me to share my positive experience with the one in my '86 model:
While driving on very congested Route 22 in NJ, I was unable to avoid driving over part of a load of rebar that had apparently been dropped on the roadway by a truck. I heard a couple of those rods hit the underside of the car, but I hoped for the best–especially in view of the reality that there was no shoulder on that highway for me to pull over. However, a few minutes later, the car was still driving normally.
Then, I connected with The Garden State Parkway, where–at even higher speeds–the car continued to drive normally.
Finally, I exited the Parkway in order to get to my home, and as soon as I slowed down on the exit ramp, I felt an extremely hard downshift. Gulp!
However, since I was only about 1/2 mile from my home, I decided to just keep going. When I parked the car and looked underneath, I was able to see trans fluid dripping on the ground, and–all told–the puddle never became very big, thus indicating that the trans was almost completely dry when I pulled into my parking area. Not good!
The next day, I had the car towed to the Ford dealership, and they reported (naturally) that it needed a new trans pan. They replaced the pan, refilled it with fluid, and sent me on my way.
The bottom line of this tale is that I drove the car for another 3+ years, and put another 35k miles on it, with no trans problems whatsoever. If the trans had been a really bad design, I would think that driving it on very low fluid for about 20 miles–and then on almost no fluid at all–would have ruined it, but–luckily–that was not the case.
Perhaps the transmissions of Tauruses in later years were badly designed, but I had no complaints about the one in my '86 Taurus.
