Greetings, My 1999 RX300 is about to pass 100,000 miles mark. I'm thinking of replacing its transmission and steering fluid for the first time and have a few questions.
1- Is this something I can undertake with a fluid/oil extractor pump or is it something best left to a pro shop?
2- What would be the right extractor for this application? A simple multi-use transfer pump, a fluid/oil extractor a fancy fluid extractor?
3- What is the best fluid to use for this purpose, Toyota Dexron III or one of the newer fluids?
Currently there is no problem with either. Steering seems a bit heavy.
Thank you in anticipation of great advice.

Please checkout the sticky threads and DIYs.

Transmission -> drain and fill. If you like more challenge, do repeated drain and fills every 50 miles of driving -> repeat at least 5 times.
Steering pump -> suction pump to pull out as much and fill. Repeat 3 times with 50 miles of driving [as many turns as possible].

For fluids, stick with what Lexus recommend.
