trans has a pause in catching when accelorator depressed.

What is your question?

Sometimes now when I am turning a corner or speeding up after a coasting roll and press the gas the transmission seems to pause before catching. could the transmission be about to go? how do I change the fluid on this none service unit? Also,the check engine light comeson upon start but does not comeback on after reset code. Code is secondary air intake. HowdoI repair this I do most of the maintenance on my vehicles to save on costs.
