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 to him means 100K. I called Toyota (no Lexus dealer near by) and they said you have to pull the tranny to change the fluid and it's just not necessary. My mechanic says it IS necessary and he does NOT have to pull the transmission to change the fluid.
So what's the story?
