7AT question (and brake caliper sidenote)

09 Touring 7AT, 64,000 miles...

After searching through the other threads related to the 7AT, I'm gonna assume when you're in manual mode in the 7AT, and you're slowly coming to a stop without downshifting, the 2nd gear to 1st gear automatic downshift jerk/slight grind is normal? Most people just say to flip it over in D?

as a side note... I had the drivers side (non-sport) rear caliper seize up on Thursday, went to Bowser Nissan... They wanted $411 for a new one. Advance Auto Parts wanted $74 for a remanufactured, but make sure if and when you have to do this, you trade in the core, you keep the bracket and give them back the bracket that comes on the reman.

The caliper/piston are the same on the reman., but the bracket on the reman. doesn't have the 4 cooling fins that stick out, probably nothing, but to me it'd look goofy to not have the rears match. (see pic)
