Jogger, 2004 Lexus LS430, 29,000 mi

Rookie
When I am at a very slow speed and step on the gas the car revs to about 2000 rpm, hestiates and then jerk and then accelerates. It is very noticable at low speeds around 5 to 10 miles per hour. But from a dead stop it seems to shift fine. I had this problem for a while know it with the low low miles is a big disappointment. Suggestions before I get beat over the head for a new tranny from the dealer?

The transmission has always felt jerky at slow speeds. Lexus always told me this was normal. I finally found a TSB that addresses this problem. After all these years of Lexus telling me this was normal, I finally got Lexus to update the computer a few months ago. It works a bit better.

If I want to take off from a standing start from a signal light to attempt to pass another vehicle my vehicle seems to buckle a few times and then works normally. what type of problem am I having?
