I just learned that my 02 awd rx300 which had a tranny service by lexus at 30k miles and then by a local mechanic at 60k may not have been a full service. My local guy, providing a bid for the 90k service said std tranny service is $120 but after looking it up, said the awd is more labor as two cross bars must be removed to drop the pan and the filter is $30. So, a full flush is $200. If I wanted a basic service in which the fluid is pumped out but the pan is not dropped and filter not changed, it would be $100 ish. Given the history w/ these cars, i will do the $200 service but thought I'd share in case others wanted to know the difference. Unfortunately, I do not know what was done on the first two changes, so it is possible i have the original filter but w/ 2 fresh fluid changes. It is my understanding the filter is part of the problem on these cars as it can get clogged up, restricting fluid flow. Best case, lexus put a new filter in at 30k and fluid changed at 60k but its possible i have the original filter w/ 85k miles right now. Still better to have changed the fluid but certainly better to include a new filter though I don't know how big of a deal this is.
