My 04 F150 is a couple weeks old with about 600 miles. When I stop on a slight incline (driveway or intersection) and let off the brake my truck starts rolling. ie: I back up my driveway, tranny still in reverse, the truck will roll back down drive like it was in netural. Anyone else have this problem?

 

AKGrumpy,

The "rolling" on hills at idle with the transmission engaged is normal for these trucks.

Here are a couple of earlier threads about this:
Truck Rolling Backwards When Pulling From A Stop On A Hill

roll back in drive

I hope that helps you.

 

That’s normal, nothing to worry about.

 

Sounds like these truck have that issue. I have to mash down on the gas when starting from stop on a hill. My prior truck was manual so I didn't really notice it until reading about it.

 

That’s the nature of an automatic transmission. If the idle was set high enough to keep you from rolling on a hill it would be to high for a flat surface.

How Automatic Transmissions Work

 

I understand how an automatic transmission works. But my 97 F150 with 93000 miles on it at close to same idle speed doesn't roll away, nor does my 98 F150 at work with 178,000 mile on it. I had just never had an automatic transmission act like a standard at low idle. But if that is normal I will just learn to get use to it.

 

That’s a nice looking truck ya got there AKGrumpy

 

We tell only the true facts here...and jpdadeo is right on with his comments...


Yes that is a nice rig you have there...Enjoy...have some nanners....

 

Ya know, I've read about this before, but it doesn't happen to me. If I stop on a slight incline and take my foot off the brake, it just sits there. It acts EXACTLY like every other automatic trannny vehicle I've ever driven. And I've been driving for over 40 years!!

Any idea why that is? And I'm not talking about a high idle, either. My truck is simply right on. No backwards slipping, no shakes or shudders. Did I just get lucky, or are there lots of others out there with the same situation that just haven't bothered to comment??

 

I agree that on a slight incline the truck will hold, but I think it will roll backwards if you get to steep. My truck idles about 550 rpm’s.

 

Some vehicles will roll back and then with slight rpm's it will pick up. This has been a norm since iv'e been driving and that was in 1971 was in a 65 mustang. Torque converters are changing for the better in cars and trucks.
