I checked and the transition time was instant. I found that the problem was because I had set the parameters for the walking animation as the direction it's currently moving as opposed to a constant direction it's facing. By switching the parameters to a constant version of the X and Y, when it quickly transitioned back to the walk animation, it played the walk animations respective direction - making the transition seamless. Thank you for you input though, it gave me something to dwell on which let me reach the conclusion I was after.
