Danny Philliskirk's 21st-minute strike - his third in two games - and a second-half goal from Adam Rooney earned Oldham a tie at home to Mansfield.
Leigh Griffiths grabbed a stoppage-time consolation for Wolves but that didn't take the shine off the win at all for Johnson.
"I am really happy; it was excellent," he said.
"Not just with the result actually, just the general play. I thought that the game was played on our terms and our boys are growing up.
"Since the game against Crawley, which I felt was our lowest ebb, everyone now knows each others game and this was another excellent performance.
"The players are getting in tune with each other and that is important because our pattern, our movement, our defending, our balance is so much better than it was and that is no fluke because we have spent a lot of time working on it.
"You could say everyone was excellent. Danny could have had a hat-trick and the midfield were very good in their distribution of the ball and in their work rate.
"People can start influencing each other now and that is down to the time on the training ground.
"I think Danny's goal was deserved at the time and maybe we could have gone on to get two or three more.
"We have got to keep getting better. We haven't cracked anything yet although I do feel that we are on the right track.
"I was disappointed to concede the goal but I am not going to mention that to the lads at this stage as I am so proud of them.
"We did manage the game well and it was a nice treat for our fantastic support that travelled and now we have to kick on in the league."
