McCulloch has revealed how his Gers team-mates have still to be contacted by Newco chief executive Charles Green.
And the 34-year-old, who has pledged to play for his boyhood heroes wherever they end up playing, is unhappy at the lack of communication.
Rangers administrators Duff and Phelps had claimed players' contracts would pass from Oldco to Newco when it emerged the Glasgow club were set to go into liquidation. However, PFA Scotland chief Fraser Wishart believes the likes of Steven Davis, Allan McGregor and Steven Naismith could all walk away for free.
With pre-season drawing ever nearer, midfielder McCulloch wants their situation clarified by Green sooner rather than later.
"The boys are getting a little bit anxious," he confirmed. "We've not spoken to anybody.
"As far as I'm aware and have been told, any players can walk away. But that's if they want to walk away
"But that's getting challenged. There are people telling us you can and people telling us you can't. So I think we need some clarification on that as well.
"Everybody in agreement that there must have been things done wrong in the past, but I just think it's a little harsh that it's us that'll be getting the brunt of it."
And McCulloch feels it is Green, not manager Ally McCoist, who must come out and tell the Rangers players what the situation is.
He said: "I don't blame the manager for having his phone off. He's probably thrown the phone away by now given the amount of people."
McCulloch is approaching the end of his career and has vowed to stay and see out his playing days at Rangers even if they are placed in the Third Division.
The SPL clubs are set to vote on whether to allow Rangers Newco back into the top division on Wednesday, July 4.
Fans of rival clubs are vehemently against the Govan club being readmitted to the league and have threatened to boycott clubs voting in favour of the controversial move.
But the chairmen and chief executive are wary of the massive drop in income - the existing terms of the Sky television contract will be ripped up without Rangers - they will experience.
McCulloch is convinced whatever happens Rangers will be competitive the next occasion they take to the field.
He stated: "All I know is that with the players we have that, whatever league we end up in, we'll be trying to win."
