hello XN think this might be correct location to ask? I recently parked on a decent driveway, when leaving started engine shifted selector into R, vehicle lurches forward, had not hit gas yet kind of coasted. It was enough to startle. Then further down road, vehicle at inclined light vehicle rolled back. Is this a normal thing for Xterras because they are off road ready, like stall converter? Or just my vehicle? I did not alter VDC or OD .

They will roll back before you get up to stall speed. According to the service manual for my 2007, the stall speed is between 2200-2500rpm depending on vehicle weight, tire size, gearing and your individual converter a they vary some from the factory.

Thank you good to know, so factory would place different stall converters in trans? The stall from factory is wise but different rates is insane how does one tell what rpm it engages at?

The converters are most likely identical, but a heavier vehicle will increase the stall speed slightly, plus minor variations in manufacturing cause differences in actual stall speeds.

If you put converter A in a light truck with low gearing, say a Pro4X with its 3.36 gearing but no armor, stock 265/75/16 tires, and a half tank of gas, your actual stall speed will be closer to the 2,200rpm mark.

The same converter in a "S" trim with 3.13 gears but a set of 285/75/16 tires, a steel bumper, a full tank of gas and 4 200lb dudes in it, the stall will be closer to the 2,500 mark because of the increased load.
