If you're at the point in the loan modification process where your loan servicer is asking you to make trial modification payments, then you've almost reached your goal. But this is no time to take your foot off the gas. You still have a little ways to go before your loan is permanently modified.
Being asked to make trial modification payments is a good thing. It means that your request for modification assistance has been accepted. You're on your way to achieving your objective.
But banks don't just approve an application and return your loan to normal servicing like nothing ever happened. You have to prove that you're able to make the payments, and then you'll be offered a permanent modification.
