Is this not available with the Premium Plus package on a RX350?

i would like to get a transmission cooler so the tranny doesn't die on me after 5 years~

tranmission will probably die after 50,000 miles or so. Just kidding, hope not but my last one did.

Ok...

i am NOT sure.. but maybe only AWD models can be had with Towing Prep package

I just bought a used, excuse me, previously owned RX330 AWD and I see in the documents that it has the towing prep package. What does that mean -- do I have a transmission fluid cooler or a larger alternator?

Thanks.

i think both and radiator

According to Kelley Blue Book's Web page on the RX350, you can't put the towing prep package (TO) on a model with the Premium Plus package (PT). That's not correct.

Lexus.com is showing TO with PT on AWD models in the Midwest region, and on FWD models in the Southeast region. They're not showing it in California for some reason.

Towing Prep on the 330 and 350 is a trans fluid cooler, bigger alternator, and radiator.

does anybody know where i could find the specs on the bigger alternator?

I would also like to find out the specs on the larger alternator and the larger radiator.

I just purchased an '04 RX 330 AWD and it has the towing package (and premium plus and NAV and ML), but no trailer hitch, which is fine with me.

As far as I can tell now, the "towing prep" package (which is shown on my car's original window sticker as an extra cost option) includes a trans fluid cooler, bigger alternator, and radiator and a wiring harness at the rear left of the car which I guess is to connect the brake lights of the towed trailer. I don't intend to tow anything, so I don't care much about the wiring, but the transmission fluid cooler seems like a nice thing to have anyway for the sake of the transmission.

In normal use, what does having a larger radiator mean, and what does the larger alternator do that the normal one does not? My guess is that these are things I would not notice and may not need.

Of course, I don't "need" rain sensing wipers, either, but I got 'em and am interested to see how this works in the rain.

PS: I thought getting an RX330 would be a step up for me from my old RAV4. I was wrong. It's an elevator ride to the top. I'm very happy with this car (after a few days).

my window sticker stated $4XX for the towing prep package and it came with the hitch

i want to know how many amps the alt is so i can plan my subwoofer amp accordingly

Dusting off this thread: someone has that "Towing Prep Package" on a RX350?

Any chance of anyone knowing the P/N of the coolers?

easy place to get that from; just either google it or u could just try calling local lexus dealer parts departments and they should be able to get that info for you.

There are other hoses, lines, and brackets needed as well. I wouldn't know how feasible this is to add to your vehicle either, but if you do, please post pics.
