When a car is on a slight gradient with the auto in 'Drive' and your foot off the brake should it roll backwards or 'hold' on the gradient? I have had a VP and currently have a VS Commodore and neither would roll backwards with an idling engine, but a VE recently bought by a relative does. Is this normal with a VE Commodore, or is it a fault?
It depends on the gradient, the idle speed etc., but generally an auto will sit on a slight gradient without rolling back. The idle speed could be a little low. But I wouldn't be concerned about it if it does roll back, it shouldn't have any effect on take-off when you're out driving and have to stop on a hill.
