2013 ford taurus:
Approaching very high miles (194k) with original PTU and over the winter there are a lot of long trips. Prior to my ownership (167K) i dont know how the fluid was maintained. I now change it every 5k as when I drained it, the fluid was very dark and smelled terrible. Fords TSB says this is not an indication of failure. The fluid was still flowing nice. So what im asking is assuming the unit is not puking fluid out of it, before it blows up completely, what are the failure symptoms? One the symptoms appear is the car still driveable.
