Car Rolls in Gear on Hills

heres the deal I have a 2006 Cobalt LT with Automatic Transmission. If I stop on a hill when I let off the brake my car starts to roll backwards or forwards like im in neutral. Has anyone else noticed this with their cobalt?

I understand that. I have had about 5 cars with auto and never have seen it roll like this. At some point it usually would catch the gear and stop. Now I havent just let it roll but It seems like it has some play in it

Even with an auto, you should be pulling on your e-brake when parked. The cables won`t seize up eventually and that parking pin sure takes a beating when the car rolls back or forward and hits it. Sometimes those are just plastic pins too...I wouldn`t trust it to keep my car uphill.

Im not talking about when parked im talking about when at a light. I let go of the brake before I hit the gas and the car starts to roll

Yeah man... it happens... it's totally normal.... you're probably used to driving vehicles with a larger amount of torque... or taller gears... just get used to it.

All the GM cars that I've ever driven have done that. From trucks to cars........

Actually, since new parking brake cables are no longer run through metal tubing, they are not likely to seize up anyway. They are now run through a plastic liner inside the black sheathing. It would be hard to find a cable that would seize nowadays.

What about the pivots in the rear drums? That`s usually what seizes...

Hill assist is for manual transmissions, and the cobalt doesn`t have it. It applies the brakes for you when you push the clutch in taking off on a hill so you dont roll back. Usually for people that can`t drive stick.
