I changed the filter myself. the older one you couln't tell if it was changed the week before or had been in the car from new but definitely clogged. used toyota ATF as suugested. no problems sine and i have covered 3500m

I had a similar problem. the gearbox certainly does have a filter as does every automatic so far as i'm aware. i replaced mine along with the correct toyota fluid and have had no problem for the past 4k

interestingly it was Lexus bristol that told me Dectron 3 was OK. Nevertheless i've ordered a new pick up filter and T-iv which will hopefully tutn up tomorrow

i think the answer to that is no. they used a dextron? 3

I have a 2002 rx300 which has covered 130k. As of last month its started producing a whining noise in neutral and as as it drove through the first 2 gears. The problem was most noticeable when the engine was cold. Lexus of Brighton spent sometime, at no cost, trying to diagnosed the fault without success. I asked the opinion of a autogearbox specialist close, to where I live, who immediately suggested that the gearbox filter was blocked. I gave them the car to change the filter and transmission fluid. I doubt this included a flush as the fluid was already brown by the time i got home (1/2 mile). It did solve the problem for 200 miles! The same company are quoting £1600+vat to remove and rebuild the gearbox. I haven't yet dare ask what Lexus charge. Otherwise the car drives fine. Has anyone else encountered this problem? Would a complete flush and filter change work? I have to say it is rather disappointing. I have driven Rovers, Fords and Mercs to much higher mileages without encountering a major auto gearbox problem.

i have an rx300 2002 with 130k. after years of trouble free operation i now have a growling noise in low gears most noticeable when cold. A transmission fluid change, but not flush, cured the problem for a few hundred miles but now its back again. A local autogearbox specilaist ahas quoted £1600+vat to rebuild trasnmission. i don't know how this compared to the other car you mentioned but i have habitually run rovers, fords and mercs to much higher mileages without encountering such problem
