The Gers made a number of changes during the recent transfer window, in what was a summer of rebuilding at Ibrox.
However, all of the new additions have slotted in immediately, and Rangers have made a flying start to the 2015/16 campaign.
And Warburton said: “Things have gone well, there is no doubt about that. The way the team have gelled, the unity of the group, has probably exceeded expectation.
“It is about the team’s commitment and getting the rewards for the work that they are doing. The more we can win, the better we are."
Warburton could hardly have made a better start as Rangers manager, with the team putting in performances of a consistently high standard.
The Gers have won all nine of their Scottish Championship games so far, and they have rarely been challenged in these matches.
The Light Blues have scored a whopping 31 goals in their opening league fixtures, while they have only conceded on five occasions during that time.
Warburton's side are already nine points clear at the top of the division, and they return to action after the international break with a match against Queen of the South.
