He already told you what it was.
During the 1-2 shift the engine shuts down a couple cylinders, or fuel, to reduce the amount of torque going to the tranny and tires.
Search is your friend as mentioned before chief.
Copy and paste: "Torque Reduction" to the search menu

Transmission could also be slipping. Could have what is known as a "slide bump" happening on the 1-2. Vehicle will kinda nose over on the shift while the clutches are slipping before they grab. -Mat-

I doubt it, sounds to me like torque reduction. If a clutch is gonna slip like that, it will do it all the time, or it will slip all the way through a gear until the next gear. An engagement slip will slide on what's called the engage regression (slipping until they grab, they have converging lines on a graph where the output torque will slope downwards as the engagement pressure and input torque increase, they stabilize when the input torque settles) but it will also throw a code to the PCM most of the time. Anyhow, I'd really have to know more than what you wrote to tell for sure, but what you're describing screams "Torque Reduction" to me.
