So, I was one of the original test cases for this problem. They applied the prototype and it solved the whining problem but not the clunking problem. Last week I was in for service and they compared the new TSB kit with the kit applied to my car and there was no difference in the components or installation. They're writing-up the problem and shipping it to Lexus. Any help would be appreciated. Thanks!

You need a towing package that includes a new converter...I believe you will have to add the pigtail/wiring harness.

I have the same problem with my RX330. I see that they are taking the old if you can't fix it, feature it approach. So, they call it a design feature. Ask them where this "design feature" is disclosed in the marketing literature or the technical documentation. The best thing you can do is send a registered letter to the dealership owner and document you complaint. Lemon laws allow the dealer three attempts to fix the problem. If they can't fix it, you can invoke a refund/replacement request under the lemon law. At least that's typical of most lemon laws. My experience is that Lexus will respond. However, you may have to give them an ultimatum in writing.

This is a known problem. Happened to me and they applied fix that included changing out some transmission lines. Now if they would fix the clunking problems with the transmission on downshifting.
