If my part falls into a collider it does teleport but its buggy how do fix this?

script.Parent.Touched:Connect(function(v)
    if v.Name == "Box" then
        v.Position = Vector3.new(77, 173, -10)
    end
end)

This is a pushbox its massless and anchored false if i teleport it back it does all weird stuff like teleport to random loctions if u push it and it laggs the box out how can i fix this?
