You could drive the AT in a manual mode, which would allow more variation of engine speed. Howeve, I think the main thing is really just to not drive at one consistent condition.

The rule Ive always gone by is no higher than 55 for the first few hundred miles, but that reasonable throttle (up to 3/4) under controlled conditions is good. Some say the drive like you stole it to seat rings and other such things, but IMO that is done at the factory. The key is to heat cycle everything a few times and let things generally wear in on one another to an optimal fit, without operating at a singular stress or thermal condition.
