My Lexus ES 350 has about 120000 miles on it. I took it in to a private mechanic to get the 120K service. He gave a quote and then recommended that I have him change/flush the transmission fluid. I thought the tranny was sealed. He said that it is “sealed” and the fluid is “lifetime” but lifetime…

Lexus ES350 Transmission Fluid: change it or not at 120K?

Change it now, and change it every 25-30k miles regardless of what any owners manual says. Use ONLY Toyota fluid in it.
