Just got my G last Saturday with 35,000 miles. in the past week driving the car i have experienced two separate hard downshifts less than 20mph with the AT transmission. Have been reading about the following TSB ITB10-075 but my VIN doesn't qualify. Thinking about taking the car back to the infiniti dealer to see if they can refresh my ecu or other options. I love the car so far and hope its not an indicator of problems with the tranny to come.

Did it happen during hard braking? If so it's a rev matched downshift and can be alarming if you've never experienced it before, but is normal.

In sport the downshifts are really aggressive, especially the 3-2 (I think that's what it is...wish there was an indicator). For mine, it had that behavior before the TSB reflash and it has is after with basically no change. I personally like it, but I am sure other drivers around me are like "WFT is this clown thinking?" lol

Thanks for the input. Yes it occurred on hard braking.

That's likely all it was then. I thought I broke something the first time it happened to me.

I have this from time to time also. It is not just the rev matching of the transmission, it is an actual rough/hard downshift. This was a known issue on the 7AT's but I guess it is more rare on the 5AT's. I do not know if there was ever a specific TSB for the 5AT's
