Is a Transmission Flush needed at 84000 miles. on 2000 Toyota Avalon

Toyota dealer says in addition to the Transmission Flush, he says I need Power Steering Flush. Total for both services is about $320.00.
I have no problems with any of the above systems.

That price is not bad. I would also ask about a brake flush.
Yes it is necesary. It is called Preventive Maintenance. In fact i would done that mutch earlier.Like your engine needs oilchange all others systems that use oil or fluid the fluid needs to be replaced .Including your brake system.
Make sure whoever does the service uses BG chemicals to flush.
Yes ! I use BG products myself for almost 10 years. They great products and the company stands behind to they products even with warranty to your engine - tranmission- cooling system- brake system and power steering and they pay for repairs in case of malfunction while you using they products.
Thanks for the advice. Will do.
i agree with both guys, preventive maintenance is the answer before there is any issues. i would follow thw dealer recomendations.
