Gummosis On Limbs Of Young Cherry Tree

Question

I have a black tartan cherry I planted in the spring. It was approximately 5 ft when planted. It began shedding leaves about 3 weeks ago. No aphids no turning of leaves before dropping them. It now has honey colored gummosis on the upper limbs approximately 4 ft off the ground. I can find no cankers and have removed one spot but cannot find even a minute hole. Tree was growing great before this started
