Consider the collision between 2 bodies M1 and M2,(M1<M2) but both having the same momentum.So M1 will have a higher velocity than M2(V1>V2). Now if the velocities V1 and V2 are in the same direction and M1 collides with M2 then the momentum of M1 will increase, meaning momentum of M2 will decrease. So the momentum has got transferred from higher velocity body to lower velocity body even though the momentum of both is same.

Even if the body M2 had the higher momentum than M1 before collision after collision its velocity would still increase.

So am I correct in assuming momentum gets transferred along negative velocity gradient?

Ps: This question came to my mind in context of momentum transfer in fluid flow
