7 A/T Question

i can't compare to the 350, but the upshifting can depend on how much of a lead foot you have. i think the timing of the upshift can vary depending on how aggressive you are, because i think it adjusts itself as you drive. so if you're driving with a light foot, it'll shift earlier but if you're constantly mashing the pedal, it may hold the gear longer.

as far as the downshifting, i have noticed that. not sure why?

A few videos that I took demonstrating how odd the Nissan 7-speed transmission is. This is my '09 FX35. It needed a transmission reflash, and it made the transmission a little less jerky, but you still notice that it's very busy. Here's a few examples of how it goes into this really "low-revving" mode. I'm sure you AT'ers have noticed this before. It's long, but I just wanted to demonstrate it. If you have jerking in your transmission when you're slowing down or it holds gears longer, this is completely normal for Nissan/Infinitis. That's how they're designed and programmed.

Now here's a video of it running normally.
