Can anyone tell me if it is normal for my 2007 Grand Caravan to slip forward when facing downhill while in reverse.

 

yes normal. i think its does that so ya dont put to much strain on the clutch reverse but i could be wrong

 

Welcome to DF
What makes you think the transmission is slipping in reverse?

 

I was parked on a downhill alley facing downhill. When i put the veh in reverse took my foot off the brake it rolled forward and the only reason it stopped rolling is I applied the brake. Once i pushed the throttle it grabbed and went backwards normally but I was surprised by the forward roll.

?

 

As dodgecaravan2010sxt had said, it maybe normal. It is normal, Because you don't have enought RPM for the transmission to hold in reverse.
