Lexus RX330 transmission lag between 1st and 2nd gear, persistent issue with no fix available on Lexus RX330

Some Lexus RX330 owners report experiencing transmission lag between 1st and 2nd gear, resulting in a jerky driving experience. This issue is linked to a computer problem for which no patch is currently available, causing the engine to rev without the vehicle moving, particularly when starting from a stop or navigating through traffic. Despite Lexus's awareness of the problem, there remains no known fix, and owners have reported ongoing transmission jerking, lags, and power loss during gear shifts, even after attempts at ECM reprogramming. It is recommended that affected owners contact Lexus directly to report their issues and seek guidance on potential solutions.
