Does anyone know why a 2005 rx330 jerks (like the transmission is not shifting properly) on acceleration? Even though Lexus says, "You don't need to change the ATF", I have changed ATF/filter but still jerky on acceleration. Frustrating.....!

Use only Toyota fluid and check the "dogbone" mount, or upper torque mount. Basically, the engine mount you can see from above, towards the power steering fluid reservoir.

i agree. changing the trans fluid is a must every 30,000 miles for longevity purposes. If its jerking like that though; does it do it in all gears or just upon startup acceleration?

This is my sister's car. She knows that it jerks on acceleration but not positive about other scenarios. I charge the ATF every 10,000 miles or less.

Thanks
