I'm about to buy an 04' 330 but was a little worried about the transmission problem. Just want to know if it was affecting everyone

I am experiencing the hunting, the lag. Now I am hearing a clunk-thud after I release my gas....

MD350

My wife and I once owned an 04 Sienna with the 3.3L. We had the same issues. I would pass on the car, in my opinion. This issue made the van very unenjoyable to drive.

If I was in the market for an RX, I would go with the 350 - when I had one as a loaner, it was 1000% more predictable when shifting and shifts were nicer.

while yes the rx350 might have less of the shifting problem or not have the problem as pronounced, it has the problem too. afterall the tranny is still the same, just the engine is different. ive driven too different rx350s and its still there.

The gearbox is the same, but the gear ratios are taller in the 350.

I am experincing the exact same problem over and over again even though Lexus says I have the latest updates. The car drives good sometimes and sometimes it will thump when I take my foot of the gas. Or when i am entering a rough about and accelerating out of a corner it will do a jerky rev then slam into gear. Lexus if you are reading this post, find a solution and help us fellow RX members who are all experiencing this problem.

What are the latest updates? ECU or something part of controlling the transmisson?

MC Wong

I had my transfer case replaced. ECU reset. ANd transmission flushed. But still shifts are not smooth at times.

I was just thinking that the Highlander shares the same engine but maybe not the same transmission as the RX. Maybe that transmission might work better.

wait how many miles do you have? the transmission flush unless your car really really needs it, is useless in terms of the tranny shfiting problems. Anyone else who is having trouble with their tranny dont believe the dealer if they tell you a tranny service or flush will fix the problem. my dealer told me that also, until i got the tech to admit that it wouldn't do a damn thing.

MC Wong

I have about 55000km on my car and my case has gone to Lexus Australia which I am still waiting for a reply. Looking at my records maybe they didn't do a transmission flush. Just a reset on the ECU after the transfer case was replaced. Everytime I complain about the bad shifting at Lexus they would get a foreman to go for a drive with me. But whenever we go for a drive the car shifts smooth as silk. Go figure

And that's what a few of the Toyota dealers down here (Lexus ain't here yet) with their vehicles, but I recommended to a few of my service advisors to not wait until the vehicle cools down, but to have someone go with them for an extended trip of at least 15 minutes (on most occasions) driving around the neighborhood. More than a few times after that they encountered something issue with the tranny or some other part of the vehicle. One question I always tell them to ask the customer is how soon do you feel a problem after driving the vehicle, and that is exactly the same length that the foreman or whomever should be driving the vehicle with the customer, not just pulling it into the shop and putting up on the rack or taking it for a spin around the corner.

Acura here in Mexico will go with the customer until they can notice the problem, something that I would expect.
