user30472: If not, how is the change transaction processed?

user5406: Transactions have to spend all their inputs immediately. Essentially, any transaction splits the inputs to (at least) two destinations: the transaction's intended recipient and yourself (change).
Say you have an input with 1BTC and want to spend 0.5BTC:
                         ------- 0.5BTC (recipient)
1BTC  ---transaction----|
                         ------- 0.5BTC (change to yourself)

Any portions of the input that you don't designate to a destination become part of the transaction fee which will be claimed by the miner. 

user24925: There is no change transaction type. 
Transactions are defined as a list of inputs consumed, and outputs created, and the values assigned to those new outputs. The creator typically makes an output for a entity they wish to pay, and another output which pays excess change back to them. 
Any amount of Bitcoin left un-used by the outputs is interpreted as the fee for the transaction.
