Correct me if I'm wrong but wearing the transmission during down shifting seems unlikely as an Automatic transmission has a Liquid coupling and by its very nature eliminates wear and buffers any shock loading.

I would think its easier on the transmission than a manual shift.

Granted I don't know the inner workings of the Tiptronic but doesnt that make sense and hence the downshifting is not a problem.

In the Manual I downshift and engine brake a lot but I'm more worried about distracted drivers rear ending me so I apply a little brake for the tail lights so they get the message that I'm slowing down.
