The world number four hired the American as his coach at the start of the season and Murray said that they are still getting to grips with one another.
With Wimbledon approaching, the Scot said that he is confident Lendl, twice a finalist at SW19, will prove to be a positive influence in his coaching box.
"The more time we spend with each other the better he will understand my game and the better he will understand me as a person," said Murray.
"I will know the right questions to ask him before big matches and big tournaments. I am still learning a lot from him and hopefully that will be the case leading up to Wimbledon."
Murray has reached the semi-final at Wimbledon the last three years.
