Hesitation (jolt)

[Running Ox]

My RX330 is 2004, It is free under 80000 mile warranty.

I did ECM calibration last week. really better! I would like to recommend everybody to do it.

What year is your RX? Oops, its a 2006. What did it cost?

I'll pile on here... We have the problem too. 2005 RX 330 AWD with about 15k miles when I bought it. Has like 22k now.

It happens intermittently. It ususally happens like others have said: decel to a slow roll (<5 MPH) and then try to accelerate. It also happens at times when you come to a complete stop. You can feel a slight "clunk" as it is coming out of gear. You try to accelerate, RPM's go up, then gear kicks in with a jolt.

I disagree that this is a driving style thing. No way, no how should a tranny do this sort of thing. I can understand downshift, but a "no gear" situation.

Still searching the forum for any updates/fixes....

I wish I could remember where but I'm almost positive I have seen it addressed on this forum or the other Lexus forum.
