The QC served as the Light Blues' vice-chairman under former owner David Murray's tenure, and claims the bitter fall-outs which have followed a series of boardroom battles are "not the Rangers way".
And he attacked former chief executive Charles Green - who was last week named as a consultant by the current board just four months after quitting his original post - following a newspaper interview given by the Yorkshireman in which he told boss Ally McCoist that he faced losing his job if the League One outfit did not land a domestic cup this season.
Findlay, who stepped down as the club's vice-chairman in 1999 after he was caught on camera singing a controversial anthem, has now called for a strong figure to replace Walter Smith as chairman following the nine-in-a-row manager's decision to resign his position and lead a clear-out of disruptive figures from the boardroom.
"This is not the Rangers way," he said. "The Rangers way during my involvement with the club was that we conducted ourselves in a certain manner.
"We had our discussions, we had our arguments, we had our internal disagreements about what was the best way ahead. And then we got on to do what we thought was in the best interests of the club.
"But we did everything behind closed doors where everything was secretive.
"You don't have your private discussions out in public and start pointing fingers. And you most certainly back the manager. Anyone who doesn't has no place at Rangers Football Club in my view.
"If you are going to get rid of Ally, you do that privately.
"I don't know to what extent Walter was a figurehead or to what extent he had any real power. I have no idea.
"But it is abundantly clear that what the club needs is somebody at the helm who has Rangers' interests at heart and nothing else, who knows how to run a football club and who has been given the power to get on and do that. Someone who is able to get the people that need to be moved on out the door.
"As for Mr Green, I don't know him, I have never met him. But if you were putting down a piece of paper and listing the things he has done for the club, it wouldn't take you long."
