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?

You don’t have to pull the transmisson out. Maybe the transmission pan, but not the entire transmission. Worth doing if you are planning on keeping the car for a while.
