If the transmission "brain" in modern cars senses problems it can keep the tranny from shifting. Usually leaves you in second gear as a safety and warning indication. I don't now if that year lexus had this ability but getting it checked on a diagnostic computer that read transmission codes should shed some light on your situation.
