Jelly on peach tree limb
This is called gummosis and is common on peach trees. As long as the bark appears healthy, you do not need to worry. Although it's a natural tendency for peach trees to develop gummosis, there are other factors to watch out for: environmental stress (e.g., poor drainage or dry soil or rapid changes in weather); mechanical injury (e.g., from mowers and weed whackers); disease; and insect damage. With disease, look for cankers and lesions. With insect damage, look for holes and tunnels. If you don't see either, then it's probably just the peach tree's natural tendency.
