The correct answer is that TF-80SD is adapted for start/stop function.

I've absolutely no doubt that stop start reduces engine life - whether that's enough to reduce it to less than the life of the rest of the car is open to debate. Obviously startup is where the oil earns its stripes.

Hmmm. I was posting about the difference in the AW Transmission designations, quotes above for context.
