Was warned NOT to change my Transmission Fluid
#16
Carguy 07 is correct. BTWM the original and most heinous culprit of these tranny failures may be the old aluminum panetary gear carrier, which can distort, sending metal filings to plug up valve body, end of tranny. This was replaced by a steel carrier, ending that problem. Failure to change fluid per schedule is the next no no, and heat is a real enemy to any tranny. To my knowledge, this tranny has no "filter", but pulling the pan and looking for metal filings can sure get ones attention. The AWD diff on mine had the filler plug stripped by some incompetent, so I had the plug replaced by a competent human. No wait, that's not correct grammer. A competent human replaced the... no, wait...

The RX300 does have a transmission filter. On most models it's a steel "mesh" which won't filter out much of anything other than big chunks of metal (you may not consider that to be a "filter"). The mesh filter is no longer available and it had been replace by a fabric (of sorts) filter which will filter out small particles.

There is a throw away filter (often referred to as paper, but it's not paper) in the newer ones, post-2001, I think, but I plan on replacing the one in my wife's 2002 with a metal mesh one.
I think of it as being environmentally conscious. Plus, I'd rather clean it and see what comes out instead of making a replacement, anyway.

I read all comments from my fellow Club Lexus members. My 2002 RX300 still running well with my periodic transmission fluid changes every 30K miles. Now that I have put high mileage on my vehicle, I tend to agree that the Transmission/Filter needs replacement of my wife's car. Consult your RX300 manual that came with the car to select the proper type of ATF. Good lick to all members reading this Quote.

Burnt flud is the cause not the problem the problem is caused due to flow and the filter blocking up with shaved metal filings.
Changing the burnt fluid wont help as the new fluid will burn in days.

Changing Transmission Fluid on RX300 is easy. I did it more than once.
I have a 2002 RX 300 ~95,000mi and called around to gets some quotes on:
Transmission Fluid and Filter change
Front Diff fluid change
Transfer case fluid change
I just had the 90k service done at ~95k and also had the rear diff done at same time(was supposed to do front diff at the same time but that's another story).
Anyway my Lexus dealer specifically said Not to change the Auto Transmission Fluid and Filter because it was supposed to be done every 30k and if you've never done it before to not do it. He said several times now they've changed the fluid for the first time at higher mileages and then not long after the transmission fails. He thinks its because of the way the old and new fluids mix.
I called another mechanic who has a good reputation that I was thinking of trying out and he said the same thing, although worded less strongly. He just said yes it does definitely happen but wouldn't weigh in either way as to if he thought changing the Auto Trans fluid was a good idea or not in my situation. He agreed that its the old and new fluid mixing which can cause big problems.
So basically that leaves me on clueless island... Any thoughts???
