H3 rolling backwards

Quick question... I know this is probably stupid, but a friend of mine has an H3, she hasn't had any of the head or valve problems that I've read about here, but she does say that at a stop, she rolls backward like a standard... is that normal?  My H2 doesn't do that. It drives her nuts

is it a manual or an automatic?

It's an automatic

I only assume she was not keeping her foot on the brake???  Not?

This is normal for the H3. My H3 rolls backwards as well and it doesn't have to be a a steep incline either. Just have to keep teh foot on the break...  I don't know why...

Sounds like some transmission slop to me... probably due to pressures...
 
But I have seen it a few times...  I bet if she rolls up on a hill that it always does it on and drops it down into 1 it doesn't do it...
