But the 'Cherry and Whites' were made to work hard for their victory, and the Tykes managed to deny them an all-important bonus point, while securing themselves a bonus point – for finishing within seven points – at the same time.
New fly-half signing Duncan McRae made a good impression in his first outing in front of the Kingsholm faithful, and fed out the pass that helped unwanted England international James Simpson-Daniel to the first of his two tries.
Simpson-Daniel had flanker Andy Hazel to thank for his second try, with Hazel making a strong break before getting brought down inches from the line.
The Gloucester support reacted well and the ball was recycled through the hands of centres Henry Paul and Robert Todd, who found Simpson-Daniel in space and with gas to burn.
Flanker James Forrester added a try of his own by sneaking around the back of a ruck to surprise the visitors, and Paul put away the conversion to put the home side almost out of sight.
But the Tykes fought home and dragged themselves back into game via two Duncan Hodge penalties and a try from scrum-half Alan Dickens.
Hodge continued to close the gap during the second half, but Gloucester stood firm and a Paul penalty 10 minutes from time was enough to keep the busy visitors at bay.
